HL7Translator Class

Properties   Methods   Events   Config Settings   Errors  

The HL7Translator class is optimized for HL7 translation, providing a simple way to convert HL7 documents to and from XML or JSON.

Syntax

ipworksedi.hl7translator()

Remarks

The class provides a way to convert HL7 to XML or JSON and vice versa.

Getting Started

The class will convert a document from the format specified by InputFormat to the format specified by OutputFormat. In practice this allows for converting to XML or JSON from EDI and vice versa.

Before translating from EDI to XML or JSON it is recommended to load a schema using the LoadSchema method. This ensures additional information can be included in the XML or JSON document. If a schema is specified the XML or JSON will include types and descriptions as element attributes which are useful for interpreting the data.

EDI elements may optionally be renamed when creating XML. To define how an element is renamed add a renaming rule by calling AddRenamingRule.

After calling Translate the resulting output will contain the EDI, XML or JSON data as defined by OutputFormat. If the output data is XML the ExportXMLSchema method may be called to export a schema (.xsd) defining the structure of a valid XML document. XML documents which adhere to this document may be translated from XML to EDI.

Input and Output Properties

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

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

When a valid source is found the search stops. The order in which the output properties are checked is as follows:
  • OutputFile
  • OutputData: The output data is written to this property if no other destination is specified.

<N104 desc="Identification Code_67">544380</N104>
</N1>
The default value is False. This setting is only applicable when using ArcESB JSON schemas.

HL7Translator.addRenamingRule Method

This method adds a renaming rule to define how an EDI element is renamed when translating to XML.

Syntax

async hl7translator.addRenamingRule(rule : string): Promise<void>

Remarks

This method adds a renaming rule. The rule defining how EDI elements are renamed when translating to XML. Renaming rules are optional.

The renaming rule defines how EDI elements are renamed when translating to XML or JSON. The format is:

ediname:xmlanme
For instance: "UNH1:MsgRefNumber".

Note: Renaming rules are not required when converting from XML or JSON to EDI.

HL7Translator.config Method

Sets or retrieves a configuration setting.

Syntax

async hl7translator.config(configurationString : string): Promise<string>

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.

HL7Translator.displaySchemaInfo Method

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

Syntax

async hl7translator.displaySchemaInfo(): Promise<string>

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:

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).

HL7Translator.Warning Event

Fires whenever a validation warning is encountered.

Syntax

hl7translator.on('Warning', listener: (e: {readonly warnCode: number, readonly message: string, readonly segmentNumber: number, readonly segmentTag: string, readonly technicalErrorCode: string, readonly segmentErrorCode: string, readonly elementErrorCode: string, readonly elementPosition: number}) => void )

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:

0 The component is not required but is present.
1 Invalid segment count.
2 Invalid transaction count.
3 Invalid group count.
4 Invalid interchange control number.
5 Invalid group control number.
6 Invalid transaction control number.
10 A required data element is missing.
11 Invalid field length.
12 Invalid field value.
13 A required component is missing.
14 The data element is not defined but is present.
30 Required segment is missing.
31 Required loop is missing.
32 Occurrences exceeds the schema defined limit.
33 Occurrences is less than the schema defined minimum.
40 Paired rule validation failed, the pair of elements must be present.
41 At least one of element is required, see message for list of elements.
42 Exclusion validation failed, only one of the elements can be present.
43 Conditional rule validation failed.
44 List conditional rule validation failed.
45 First then none validation failed. The presence of an element requires that other specific elements must not be present.
46 Only one or none of the elements can be present.

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:

001The Interchange Control Numbers in the header ISA 13 and trailer IEA02 do not match.
014Invalid interchange date value (non-numeric characters or wrong length).
015Invalid interchange time value (non-numeric characters or wrong length).
022The ISA segment is missing elements (invalid control structure).
024Invalid interchange content (e.g., Invalid GS segment).

Config Settings (class ipworksedi.hl7translator)

The class accepts one or more of the following configuration settings. Configuration 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.

HL7Translator Config Settings

ComponentDelimiter:   The delimiter character to use to separate components.

When set, this changes the default delimiter to use to separate components within a data element. The default value depends on the EDI specification being used. This should be set after setting EDIStandard. Setting EDIStandard resets the default delimiter value.

CrossFieldValidationEnabled:   Enables cross-field validation rules.

If true, cross-field validation rules present in the document schema will be checked. The default value is false. Note, Bots Schema Files do not support syntax rules, therefore CrossFieldValidation rules will never execute for these schemas.

ElementDelimiter:   The delimiter character to use to separate data elements.

When set, this changes the default delimiter to use to separate data elements within a segment. The default value depends on the EDI specification being used.

Encoding:   The character encoding to be applied when reading and writing data.

If the data contains non-ASCII characters this setting should be specified so characters are properly preserved. This value should be set to a valid character set such as "UTF-8" or "ISO-8859-1".

IncludeEmptyElements:   Whether to include empty data elements in a composite element.

When translating to EDIFACT or X12 this setting specifies whether empty data elements of a composite element will be included. For instance when set to True (default) a segment may look like:

PYT+8+COLLECT:::+25'
When set to False empty data elements are not include and a segment may look like:
PYT+8+COLLECT+25'
IncludeFooters:   Whether to include footer information in the XML.

This setting specifies whether footer information is included in the translated XML. For EDIFACT this includes UNT, UNE, and UNZ. For X12 this include GE, SE, and IEA. The default value is True.

JSONElementPrefix:   An optional prefix for reserved names when translating to JSON.

This setting optionally specifies a prefix to prepend to the meta, type, desc, and value JSON elements when translating to JSON. This may be set to any ASCII character if desired. For instance:

//use the '@' character translator.Config("JSONElementPrefix=@"); Will result in JSON like:

{
	"@meta": {
		"@type": "Interchange",
		"ISA01": {
			"@desc": "Authorization Information Qualifier",
			"@value": "00"
		},

The default value is empty string and no prefix is used.

LastIXControlNumber:   The control number of the most recently parsed interchange.

This setting may be queried from within events. For instance from within the Warning event it may be desirable to know which interchange control number the warning applies to; in that case querying this setting from within Warning will return the expected value.

LastTransactionControlNumber:   The control number of the most recently parsed transaction.

This setting may be queried from within events. For instance from within the Warning event it may be desirable to know which transaction control number the warning applies to; in that case querying this setting from within Warning will return the expected value.

ReleaseChar:   The character to use to escape delimiters within values.

When set, this changes the default escape character. The default value depends on the EDI specification being used.

RenamingRulesData:   The renaming rules data.

This setting may be used to get or set renaming rules without using a file on disk. When calling SaveRenamingRules or LoadRenamingRules set the RuleFile parameter of the method to empty string to use the value in this setting instead of a file on disk. For instance: //Save Renaming Rules editranslator.SaveRenamingRules(""); string ruleData = editranslator.Config("RenamingRulesData");

//Load Renaming Rules editranslator.Config("RenamingRulesData=" + ruleData); editranslator.LoadRenamingRules("");

RepetitionChar:   The repetition character.

When set, this changes the default repetition character. The default value depends on the EDI specification being used.

SegmentDelimiter:   The delimiter character to use to separate segments.

When set, this changes the default delimiter to use to separate segments within an EDI document. The default value depends on the EDI specification being used.

StrictSchemaValidation:   Specifies the behavior during schema validation.

This setting specifies what happens when performing schema validation and a validation warning occurs. By default this value is set to 1 (Warn) and the Warning event will fire, but processing will not stop. See the WarnCode parameter list in the Warning event for details about possible validation warnings. Possible values for this setting are:

0 (Ignore) All validation warnings will be ignored. Warning will not fire with warnings.
1 (Warn - default) The Warning event will fire with all validation warnings.
2 (Error) All validation warnings are treated as errors and will cause an exception. Processing will stop immediately.

UseXMLComments:   Whether the human readable description is stored as an attribute or XML comments.

When translating to XML the human readable description of the element will be included in the output. This setting specifies whether the description is present as an attribute of the XML element, or preceding the XML element as a XML comment. For instance:

UseXMLComments is True or 1:

<!--Entity Identifier Code-->
<N101><!--Ship To-->ST</N101>

UseXMLComments is False or 0 (default):

<N101 desc="Entity Identifier Code">ST</N101>

The special value 2 tells the class to omit all comments. For instance:

UseXMLComments is 2:

<N101>ST</N101>
This setting is False (0) by default.

Base Config Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

CodePage:   The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
  • Last Valid Build: The last valid build number for which the license will work.
MaskSensitive:   Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is false.

This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

UseInternalSecurityAPI:   Tells the class whether or not to use the system security libraries or an internal implementation.

When set to false, the class will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this setting to true tells the class to use the internal implementation instead of using the system security libraries.

This setting is set to false by default on all platforms.
