DeleteSelectionPrefix (XmlDoc subroutine)

Delete prefix's XPath-selection association (XmlDoc class)

DeleteSelectionPrefix is a member of the XmlDoc class.

This subroutine removes any XPath selection association for the node name prefix identified by its string argument. DeleteSelectionPrefix is new as of version 7.0 of the Sirius Mods.

Syntax

doc:DeleteSelectionPrefix( prefix)

Syntax terms

doc

An XmlDoc object expression.

prefix

A string prefix (the part of the name before the colon) for a node. This is a Unicode string argument; prior to Sirius Mods version 7.6, this is an EBCDIC string.

Usage notes

This method has no cancellation conditions other than the usual requirement that the method object not be Null.

Example

In the following example fragment, a prefix is temporarily used in an XPath expression, then deleted:

     ...
    %doc:SelectionNamespace('tempP') = 'urn:localxxx'
    %node = %inpNode:SelectSingleNode('tempP:infoChild')
    %doc:DeleteSelectionPrefix('tempP')
     ...
