The XMLNode API provides methods to query values from XML nodes. XMLNodes are extracted from XMLDocument2 objects, which contain XML strings.

There are no constructors for creating a stand alone instance of an XMLNode object. Instead, use the createElement() method of XMLDocument2, which adds a node to an existing document.

Scoped XMLNode - getAttribute(String attribute)

Gets the value of the attribute.

Table 1. Parameters
Name Type Description
attribute String Name of the attribute.
Table 2. Returns
Type Description
String The attribute's value.

Example

var xmlString = "<test>" +
                "  <one>" +
                "    <two att=\"xxx\">abcd1234</two>" +
                "    <three boo=\"yah\" att=\"yyy\">1234abcd</three>" +
                "    <two>another</two>" +
                "  </one>" +
                "  <number>1234</number>" +
                "</test>";

Scoped XMLNode - isCDATANode()

Indicates whether the CDATA node is preserved as a separate node.

Use the Scoped XMLDocument2 - setEnableCDATAReporting(Boolean enable) method to ensure that CDATA nodes are preserved and not handled as text.

Table 19. Parameters
Name Type Description
None
Table 20. Returns
Type Description
Boolean Flag that indicates whether a queried node is CDATA or plain text.
Valid values:
  • true: The node queried is CDATA.
  • false: The node queried is plain text.

Example

The following example shows how to parse an XML string with CDATA reporting enabled using Scoped XMLDocument2 - setEnableCDATAReporting(Boolean enable). The code uses isCDATANode() to show that the first node queried in the XML string is a CDATA node.

var xmlString = "<test>" +
  "  <one>" +
  "    <two att=\"xxx\">abcd1234</two>" +
  "    <three boo=\"yah\" att=\"yyy\">1234abcd</three>"+
  "    <four><![CDATA[another]]>element</four>" +
  "  </one>" +
  "  <number>1234</number>" +
  "</test>";
var xmlDoc = new XMLDocument2();
xmlDoc.setEnableCDATAReporting(true); // Enables CDATA reporting
xmlDoc.parseXML(xmlString);
var content = xmlDoc.getFirstNode('/test/one/four');
gs.info(content.getFirstChild().isCDATANode());

Output:

true

Scoped XMLNode - toString()

Returns the string value of the current node.

Table 21. Parameters
