Name (without prefix) of selected node (XmlDoc and XmlNode classes)

LocalName returns the "local name" (the name ignoring any prefix and colon) of the node that is the head of an XPath result.

Syntax

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

Syntax terms

%unicode A Unicode string variable for the returned name.
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).

Usage notes

  • The local name is defined to be:
    • The local part of the element-type or attribute name, if the node is an Element or Attribute, respectively. This does not include any namespace prefix or following colon.
    • The processing instruction's target, if the node is a PI. (A PI node does not have a namespace prefix.)
    • Other node types will return the null string.
  • This function may only be used if the XmlDoc's Namespace property is On.
  • As of "Sirius Mods" Version 7.3, LocalName's argument and result may include only non-null EBCDIC characters that translate to Unicode. As of "Sirius Mods" Version 7.6, these strings are Unicode or are converted to Unicode.

    For more information about the effects of this version 7.6 change, see "Strings and Unicode with the XmlDoc API". For an example of a specific effect that involves the Value method, see this example.

Examples

  1. In the following example, the part of the first name after the colon, and the entire second name (which does not have a prefix) are printed:

    begin %d oject xmlDoc %d = new %n1 object xmlNode %n1 = %d:addElement('foo:bar', , 'ftp:here') Print %n1:LocalName< %n1 = %n1:AddElement('junk') Print %n1:LocalName end

    The example result follows:

    bar junk

Request-Cancellation Errors

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