XPath Property
Provides a way to point to a specific element in the document.
Syntax
public var xPath: String {
get {...}
set {...} }
Default Value
""
Remarks
XPath implements a subset of the XML XPath specification, allowing you to point to specific elements in the XML response.
The path is a series of one or more element accessors separated by '/'. The path can be absolute (starting with '/') or relative to the current XPath location.
The following are possible values for an element accessor:
'name' | A particular element name. |
[i] | The i-th subelement of the current element, starting at index 1. |
.. | the parent of the current element. |
Example (Setting XPath)
Document root QBObjectControl.XPath = "/" Specific Element QBObjectControl.XPath = "/root/SubElement1/SubElement2/" i-th Child QBObjectControl.XPath = "/root/[i]"
You may use the HasXPath method to determine if an xpath exists before setting the XPath property.
If an error occurs when setting this property an error will not be thrown. This property has a related method which will throw an error:
public func setXPath(xPath: String) throws
