SAX GET XML ELEMENT VALUE


SAX GET XML ELEMENT VALUE ( document ; value )

Parameter	Type	Description
document	DocRef	Reference of open document
value	Text, BLOB	Element value

Description

The SAX GET XML ELEMENT VALUE command allows you to get the value of an XML element that exists in the XML document referenced in the document parameter. This command must be called with the XML DATA SAX event. For more information about SAX events, refer to the description of the SAX Get XML node command.

Pass a Text or BLOB type variable in the value parameter. If you pass a BLOB, the command will automatically attempt to decode it into base64.

Example

Let's look at the following piece of XML code:

<RootElement>
   <Child Att1="111" Att2="222" Att3="333">MyText</Child>
</RootElement>

The following instruction will return “MyText” in vValue:

SAX GET XML ELEMENT VALUE(DocRef;vValue)

System variables and sets

If the command was executed correctly, the system variable OK is set to 1. Otherwise, it is set to 0 and an error is generated.
