Default URI in scope at selected node (XmlDoc and XmlNode classes)

The DefaultURI function returns the Uniform Resource Identifier (URI) associated with the default namespace declaration that is in scope at a node that is the head of an XPath result.

Syntax

%unicode = nr:DefaultURI[( [xpath])] Throws XPathError

Syntax terms

%unicode A string variable for the returned URI.
nr An XmlDoc or XmlNode, used as the context node for the xpath expression. If an XmlDoc, the Root node is the context node.
xpath A Unicode string that is an XPath expression that results in a nodelist. The head of the nodelist is the node to process. An optional argument, its default is a period (.), that is, the node referenced by the method object (nr).

Prior to "Sirius Mods" Version 7.6, this is an EBCDIC string.

Usage Notes

Examples

  1. In the following example, two elements are added along with their namespace URIs, but only the second added element, which has no prefix, has a default namespace URI:

    begin %d object xmlDoc auto new %n object xmlNode %n2 object xmlNode %n = %d:addElement('p:top', , 'urn:top') %n2 = %n:addElement('inner', , 'urn:default') %n:print print 'URI of p:top default namespace =' and %n:defaultURI print 'URI of inner default namespace =' and %n2:defaultURI end

    The following lines are printed:

    <p:top xmlns:p="urn:top"> <inner xmlns="urn:default"/> </p:top> URI of p:top default namespace = URI of inner default namespace = urn:default

Request-Cancellation Errors

  • XmlDoc Namespace property not On.
  • XPath is invalid.
  • Result of (XPath) is empty.
  • Insufficient free space exists in CCATEMP.
