EDIFACTReader Class

Properties   Methods   Events   Config Settings   Errors  

The EDIFACTReader class is optimized for EDIFACT documents, providing a simple way to parse EDIFACT documents.

Syntax

ipworksedi.Edifactreader

Remarks

The class allows you to parse an incoming EDI document. This class works in two states, loading an entire document at once, or streaming portions of the document. These states are controlled by the BuildDOM property. By default BuildDOM is set to bdEntireDocument which parses the entire document at once, allowing you to use the XPath property to navigate the document.

To save memory for larger documents, you can choose to parse only sections of the document, instead of the entire document. When BuildDOM is set to per interchange (bdInterchange ) or per transaction (bdTransaction), the respective section of the document will be available for use with XPath from within the corresponding Start and End events. Finally, you may choose to set BuildDOM to bdNone, which means no DOM will be built and all data will be available only through events, but also will use very little memory. Below are example steps to parse an entire document:

1. First, use LoadSchema to load a schema file into the class. (Only necessary when preserving document structure).
2. Open an EDI document or stream by setting input via SetInputStream, InputFile or InputData and calling Parse.
3. If BuildDOM is set to bdEntireDocument, the events of the class will fire as the document is parsed, and XPath may be set to access any part of the document.

   If bdInterchange or bdTransaction are specified, Parse is called the entire document will be parsed, with only the specified section being saved in memory at any given time. This means if you wish to set XPath to navigate within the section of the document, you will need to do so within the events of the class to prevent further processing of the document while you access the section. When parsing is completely, only the most recently parsed section will be available for use with XPath

   If bdNone is specified, then all document information must be obtained through the events fired during parsing.

During parsing, the class performs basic validation of the incoming document. If validation fails, a warning is generated (fired as an event).

The XPath navigation is done through the XPath property. For example: EDIReader.XPath = "/IX[1]/FG[1]/TX[2]/N1Loop1[1]/N1[1]"; This example path means the following: Select the first N1 segment within the first iteration of the N1Loop1, within second transaction in the first functional group and interchange.

You can also make use of XPath conditional statements to locate the first element which matches a name=value. For example, you could use the following XPath to locate the path of the first element within any N1Loop1 that has a name=N101 and value=BT: EDIReader.XPath = "IX[1]/FG[1]/TX[1]/N1Loop1[N101='BT']";

Note that the conditional statements will search the children, but not the grand children of the element on which the conditional statement is applied. For instance in the above example the children of N1Loop1 will be searched, but the grandchildren will not.

Additionally if the schema loaded is a ArcESB JSON schema the element Id (from the schema) can be used in the conditional statement. For instance instead of N101 the following is also acceptable: EDIReader.XPath = "IX[1]/FG[1]/TX[1]/N1Loop1[98='BT']";

To display the structure of the parsed document use DisplaySchemaInfo. This is helpful when deciding how to navigate the document.

Config Settings

The following is a list of config settings for the class with short descriptions. Click on the links for further details.

BuildDOM Property (EDIFACTReader Class)

When True, an internal object model of the EDI document is created.

Syntax

public int getBuildDOM();


public void setBuildDOM(int buildDOM);


Enumerated values:
  public final static int bdEntireDocument = 0;
  public final static int bdInterchange = 1;
  public final static int bdTransaction = 2;
  public final static int bdNone = 3;

Default Value

0

Remarks

Set BuildDOM to bdEntireDocument (0) when you need to browse the current document through XPath.

Use bdInterchange (1) when parsing large documents to tell the class to only hold an internal object model of the current Interchange being parsed. When this value is used, and a new Interchange is encountered during parsing, the old interchange is cleared from memory. If the input contains a single Interchange, this is equivalent to using bdEntireDocument.

Use bdTransaction (2) when parsing large documents to tell the class to only hold an internal object model of the current transaction being parsed. When this value is used, and a new transaction is encountered during parsing, the old transaction is cleared from memory.

A value of bdNone (3) will tell the class to not save any internal state of the document being parsed, and thus XPath will be unavailable.

EDIStandardVersion Property (EDIFACTReader Class)

The version of the EDI specification.

Syntax

public String getEDIStandardVersion();

Default Value

""

Remarks

This property will be populated after parsing begins and the correct version string for is located via the schema, such as 004010 for X12.

This property is read-only and not available at design time.

ExtraData Property (EDIFACTReader Class)

Extra data that has not been parsed by the class.

Syntax

public String getExtraData();

Compiles an existing XSD schema into an optimized binary representation.

Syntax

public void compileSchema(String xsdSchema, String binSchema);

Remarks

This method parses XsdSchema and generates an optimized binary representation that is saved into the path referenced by BinSchema. Binary schemas are smaller and require less resources when loading later using LoadSchema

If the schema file does not exists or cannot be parsed as an EDI schema, the component throws an exception.

Config Method (Edifactreader Class)

Sets or retrieves a configuration setting.

Syntax

public String config(String configurationString);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

DisplaySchemaInfo Method (Edifactreader Class)

Returns a string showing the structure of the schema defining the document.

Syntax

public String displaySchemaInfo();

Remarks

After calling LoadSchema this may be called to obtain information about the structure of the schema defining the document. If the desired XPath is not known this helps determine the structure so that the correct XPath can be built.

Note: A valid schema must be loaded via LoadSchema.

For instance: Console.WriteLine(component.DisplaySchemaInfo()); Will output text like:

DisplayXMLInfo Method (Edifactreader Class)

Returns a string showing the structure of the parsed document as XML.

Syntax

public String displayXMLInfo();

Remarks

After the EDI document has been parsed this method may be called to obtain information about the document structure. The parsed data is represented as XML when queried. This shows all parsed data and may be useful for testing and debugging purposes. For instance: Console.WriteLine(component.DisplayXMLInfo()); Will output text like:

<IX tag="ISA" ISA01="00" ISA02="          " ISA03="00" ISA04="          " ISA05="ZZ" ISA06="ACME           " ISA07="ZZ" ISA08="WAYNE_TECH     " ISA09="160707" ISA10="1544" ISA11="U" ISA12="00401" ISA13="000000006" ISA14="0" ISA15="T" ISA16=">">

Flush Method (Edifactreader Class)

Flushes the parser and checks its end state.

Syntax

public void flush();

Remarks

When Flush is called, the parser flushes all its buffers, firing events as necessary, and then checks its end state.

Any extra un-parsed data will be populated in the ExtraData property after this method is called.

GenerateAck Method (Edifactreader Class)

Generates an EDI acknowledgement.

Syntax

public String generateAck();

Remarks

This functionality is not yet implemented and is reserved for future use.

HasXPath Method (Edifactreader Class)

Determines whether a specific element exists in the document.

Syntax

public boolean hasXPath(String XPath);

Remarks

This method determines whether a particular XPath exists within the document. This may be used to check if a path exists before setting it via XPath.

This method returns True if the xpath exists, False if not.

See XPath for details on the XPath syntax.

LoadSchema Method (Edifactreader Class)

Loads a schema file describing a Transaction Set.

Syntax

public void loadSchema(String fileName);

Remarks

This method parses the File and loads it into an internal schema list. The class will attempt to automatically detect the SchemaFormat.

If the schema file does not exist or cannot be parsed as an EDI schema, the class throws an exception.

LoadSchemaStream Method (Edifactreader Class)

Loads a schema stream describing a Transaction Set.

Syntax

public void loadSchemaStream(java.io.InputStream schemaStream);

Remarks

Parses Stream and loads it into an internal schema list. The SchemaFormat property must be set before calling this method.

The following SchemaFormat values are supported when calling this method:

• schemaBinary
• schemaBizTalk
• schemaSEF

Parse Method (Edifactreader Class)

Parse the specified input data.

Syntax

public void parse();

Remarks

This method parsed the input data specified by SetOutputStream, InputFile or InputData.

During parsing the following events may fire:

• StartInterchange
• StartFunctionalGroup
• StartTransaction
• Segment
• StartLoop
• EndLoop
• EndTransaction
• EndFunctionalGroup
• EndInterchange

After Parse returns the document may be traversed by setting the XPath property. The XPath navigation is done through the XPath property. For example: EDIReader.XPath = "/IX[1]/FG[1]/TX[2]/N1Loop1[1]/N1[1]"; This example path means the following: Select the first N1 segment within the first iteration of the N1Loop1, within second transaction in the first functional group and interchange.

You can also make use of XPath conditional statements to locate the first element which matches a name=value. For example, you could use the following XPath to locate the path of the first element within any N1Loop1 that has a name=N101 and value=BT: EDIReader.XPath = "IX[1]/FG[1]/TX[1]/N1Loop1[N101='BT']";

Note that the conditional statements will search the children, but not the grand children of the element on which the conditional statement is applied. For instance in the above example the children of N1Loop1 will be searched, but the grandchildren will not.

Additionally if the schema loaded is a ArcESB JSON schema the element Id (from the schema) can be used in the conditional statement. For instance instead of N101 the following is also acceptable: EDIReader.XPath = "IX[1]/FG[1]/TX[1]/N1Loop1[98='BT']";

Input Properties

The class will determine the source of the input based on which properties are set.

The order in which the input properties are checked is as follows:

• SetInputStream
• InputFile
• InputData

InputData Notes

When setting data to parse via InputData fragments or complete documents may be specified. To parse data in chunks set InputData and call Parse for each fragment.

When the parser is finally reset via the Reset method, all buffered text is flushed out through the ExtraData property.

Since the class can be used to parse EDI data fragments, the internal buffer will not be cleared until Reset is called. If you plan to use this method to parse multiple complete EDI documents be sure to call Reset between calls.

Reset Method (Edifactreader Class)

Resets the parser.

Syntax

public void reset();

Remarks

When called, the parser flushes all its buffers, firing events as necessary, and then initializes itself to its default state.

Reset must also be used as signal to the parser that the current stream of text has terminated.

SetInputStream Method (Edifactreader Class)

Sets the stream from which the class will read the data to parse.

Syntax

public void setInputStream(java.io.InputStream inputStream);

Remarks

This method sets the stream from which the class will read the data to parse.

Input Properties

The class will determine the source of the input based on which properties are set.

The order in which the input properties are checked is as follows:

• SetInputStream
• InputFile
• InputData

TryXPath Method (Edifactreader Class)

Navigates to the specified XPath if it exists.

Syntax

public boolean tryXPath(String xpath);

Remarks

This method will attempt to navigate to the specified XPath parameter if it exists within the document.

If the XPath exists the XPath property will be updated and this method returns True.

If the XPath does not exist the XPath property is not updated and this method returns False.

EndFunctionalGroup Event (Edifactreader Class)

Fires whenever a control segment is read that marks the end of an interchange.

Syntax

public class DefaultEdifactreaderEventListener implements EdifactreaderEventListener {
  ...
  public void endFunctionalGroup(EdifactreaderEndFunctionalGroupEvent e) {}
  ...
}

public class EdifactreaderEndFunctionalGroupEvent {
  public String tag;
  public String controlNumber;
  public int count;
  public String fullSegment;
}

Remarks

The EndFunctionalGroup event will fire when a control segment marking the end of a functional group is read. The Tag parameter contains the tag of the segment, such as GE. ControlNumber contains the control number associated with the segment, and links this event with the corresponding StartFunctionalGroup event. Count contains the value of the count element included in the closing segment, which identifies the number of transactions in a functional group.

EndInterchange Event (Edifactreader Class)

Fires whenever a control segment is read that marks the end of an interchange.

Syntax

public class DefaultEdifactreaderEventListener implements EdifactreaderEventListener {
  ...
  public void endInterchange(EdifactreaderEndInterchangeEvent e) {}
  ...
}

public class EdifactreaderEndInterchangeEvent {
  public String tag;
  public String controlNumber;
  public String fullSegment;
}

Remarks

The EndInterchange event will fire when a control segment marking the end of an interchange is read. The Tag parameter contains the tag of the segment, such as IEA. ControlNumber contains the control number associated with the segment, and links this event with the corresponding StartInterchange event.

EndLoop Event (Edifactreader Class)

Fires when the end of a loop is detected in a transaction set.

Syntax

public class DefaultEdifactreaderEventListener implements EdifactreaderEventListener {
  ...
  public void endLoop(EdifactreaderEndLoopEvent e) {}
  ...
}

public class EdifactreaderEndLoopEvent {
}

Remarks

The EndLoop event will fire after the last segment in a loop is read. Each EndLoop event is paired with one StartLoop event.

EndTransaction Event (Edifactreader Class)

Fires whenever a control segment is read that marks the end of a transaction.

Syntax

public class DefaultEdifactreaderEventListener implements EdifactreaderEventListener {
  ...
  public void endTransaction(EdifactreaderEndTransactionEvent e) {}
  ...
}

public class EdifactreaderEndTransactionEvent {
  public String tag;
  public String controlNumber;
  public int count;
  public String fullSegment;
}

Remarks

The EndTransaction event will fire when a control segment marking the end of a transaction is read. The Tag parameter contains the tag of the segment, such as SE. ControlNumber contains the control number associated with the segment, and links this event with the corresponding StartTransaction event. Count contains the value of the count element included in the closing segment, which identifies the number of segments in a transaction set.

Error Event (Edifactreader Class)

Fired when information is available about errors during data delivery.

Syntax

public class DefaultEdifactreaderEventListener implements EdifactreaderEventListener {
  ...
  public void error(EdifactreaderErrorEvent e) {}
  ...
}

public class EdifactreaderErrorEvent {
  public int errorCode;
  public String description;
}

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class throws an exception.

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

ResolveSchema Event (Edifactreader Class)

Fires whenever a new transaction set is encountered and no schema is found for it.

Syntax

public class DefaultEdifactreaderEventListener implements EdifactreaderEventListener {
  ...
  public void resolveSchema(EdifactreaderResolveSchemaEvent e) {}
  ...
}

public class EdifactreaderResolveSchemaEvent {
  public String transactionCode;
  public String standardVersion;
}

Remarks

The ResolveSchema event will fire when a the class encounters the header segment of a new transaction set, but it finds no schema corresponding to it already loaded.

TransactionCode contains the code of the transaction, such as "810" or "APERAK".

StandardVersion contains the version of the transaction, such as "004010" or "D95A".

When processing this event, the caller can use LoadSchema() to load a new schema into the class that can be used to parse the transaction.

After the event fires, if the class still doesn't have a matching schema, then it will attempt schema-less parsing of the transaction set.

Segment Event (Edifactreader Class)

Fires whenever a data segment in a transaction set is read.

Syntax

public class DefaultEdifactreaderEventListener implements EdifactreaderEventListener {
  ...
  public void segment(EdifactreaderSegmentEvent e) {}
  ...
}

public class EdifactreaderSegmentEvent {
  public String tag;
  public String name;
  public String loopName;
  public String fullSegment;
}

Remarks

The Segment event will fire when a data segment is read. The Tag parameter contains the tag of the segment. Name contains the name of the segment as defined in the associated transaction set schema. LoopName contains the name of the loop or group this segment is present in (such as N1Loop1).

StartFunctionalGroup Event (Edifactreader Class)

Fires whenever a control segment is read that marks the start of a functional group.

Syntax

public class DefaultEdifactreaderEventListener implements EdifactreaderEventListener {
  ...
  public void startFunctionalGroup(EdifactreaderStartFunctionalGroupEvent e) {}
  ...
}

public class EdifactreaderStartFunctionalGroupEvent {
  public String tag;
  public String controlNumber;
  public String fullSegment;
}

Remarks

The StartFunctionalGroup event will fire when a control segment marking the start of a functional group structure is read. The Tag parameter contains the tag of the segment, such as GS. ControlNumber contains the control number associated with the segment.

StartInterchange Event (Edifactreader Class)

Fires whenever a control segment is read that marks the start of an interchange.

Syntax

public class DefaultEdifactreaderEventListener implements EdifactreaderEventListener {
  ...
  public void startInterchange(EdifactreaderStartInterchangeEvent e) {}
  ...
}

public class EdifactreaderStartInterchangeEvent {
  public String tag;
  public String controlNumber;
  public String fullSegment;
}

Remarks

The StartInterchange event will fire when a control segment marking the start of an interchange structure is read. The Tag parameter contains the tag of the segment, such as ISA. ControlNumber contains the control number associated with the segment.

StartLoop Event (Edifactreader Class)

Fires when the starting of a loop is detected in a transaction set.

Syntax

public class DefaultEdifactreaderEventListener implements EdifactreaderEventListener {
  ...
  public void startLoop(EdifactreaderStartLoopEvent e) {}
  ...
}

public class EdifactreaderStartLoopEvent {
  public String name;
}

Remarks

The StartLoop event will fire when the tag of a loop trigger segment is read. The Name parameter contains the schema-provided name of the loop, such as "N1Loop1".

StartTransaction Event (Edifactreader Class)

Fires whenever a control segment is read that marks the start of a transaction.

Syntax

public class DefaultEdifactreaderEventListener implements EdifactreaderEventListener {
  ...
  public void startTransaction(EdifactreaderStartTransactionEvent e) {}
  ...
}

public class EdifactreaderStartTransactionEvent {
  public String tag;
  public String controlNumber;
  public String code;
  public String fullSegment;
}

Remarks

The StartTransaction event will fire when a control segment marking the start of a transaction is read. The Tag parameter contains the tag of the segment, such as ST. ControlNumber contains the control number associated with the segment. Code contains the transaction code (such as 810).

Warning Event (Edifactreader Class)

Fires whenever a validation warning is encountered.

Syntax

public class DefaultEdifactreaderEventListener implements EdifactreaderEventListener {
  ...
  public void warning(EdifactreaderWarningEvent e) {}
  ...
}

public class EdifactreaderWarningEvent {
  public int warnCode;
  public String message;
  public int segmentNumber;
  public String segmentTag;
  public String technicalErrorCode;
  public String segmentErrorCode;
  public String elementErrorCode;
  public int elementPosition;
}

Remarks

The Warning event will fire during parsing of a segment of an EDI document. The WarnCode parameter contains the type of warning encountered. Message is a textual description of the problem. SegmentNumber is the index of the segment where the problem was found.

SegmentTag holds the tag name of the segment. SegmentErrorCode holds the error code that may be used in the IK304 field of a 999. ElementErrorCode holds the error code that may be used in the IK403 field of a 999. ElementPosition is the position of the element where the error occurred.

It's very important to note that segment validation happens right in the middle of the parsing process. Because of this, the Warning event will usually fire long before the validated segment becomes the current segment for the parser state. This means you cannot access the parser properties to examine the current segment in relation with the Warning event when the event fires.

Possible WarnCode values are:

TechnicalErrorCode holds a technical error code that helps identify structural issues with the document. For instance when parsing an X12 document this will hold values that may be used for TA1 error codes. When parsing X12 documents the following codes are applicable:

EDIElement Type

An Element within an EDI Segment.

Remarks

An EDI Segment contains one or more Elements. Elements can either be simple (they just contain a value) or they may be composite (containing more than one Component).

A simple element will simply contain a Value. For a composite element you must iterate over the components it contains by setting the ComponentIndex field, and then using the ComponentValue field to get the value at the corresponding index.
