DOM GET XML ELEMENT VALUE 


 

DOM GET XML ELEMENT VALUE ( elementRef ; elementValue {; cDATA} ) 
Parameter Type   Description
elementRef  String in XML element reference
elementValue  Variable in Value of the element
cDATA  Variable in Contents of the CDATA section

The DOM GET XML ELEMENT VALUE command returns, in the elementValue parameter, the value of the XML element designated by elementRef. 4D will attempt to convert the value obtained into the same type as that of the variable passed as parameter.

The optional cDATA parameter is used to retrieve the contents of the CDATA section(s) of the elementRef XML element. Like with the elementValue parameter, 4D will attempt to convert the value obtained into the same type as that of the variable passed as parameter.

Note: If the element designated by elementRef is a BLOB processed by the DOM SET XML ELEMENT VALUE command, it has been automatically encoded in base64. Therefore the command will automatically attempt to decode it in base64.

Example  

This method returns the value of the $xml_Element_Ref element:

 C_TEXT($xml_Element_Ref)
 C_REAL($value)
 
 DOM GET XML ELEMENT VALUE($xml_Element_Ref;$value)

If the command has been correctly executed, the system variable OK is set to 1. If an error occurs, it is set to 0.
