Delete prefix's XPath-selection association (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') ...
See also
- The IsSelectionPrefix method is useful in conjunction with DeleteSelectionPrefix.
- The SelectionNamespace method specifies the namespace URI associated with a prefix, when the prefix is used in an XPath expression.
