    • The XMLDocument2 API is a JavaScript object wrapper for parsing and extracting XML data from an XML string.

    Use this JavaScript class to create an object from an XML string, usually a return value from a web-service invocation, or the XML payload of ECC Queue. Using the XMLDocument2 object in a JavaScript business rule lets you query values from the XML elements and attributes directly.

    An XML string has a tree structure, and the parts of the structure are called nodes. An XMLDocument2 object deals with two node types, element, and document element. An element node is a node with a name and possibly attributes and child nodes. A document-element node is the root node of the XML tree. It is the only node without a parent node.

    주:
    This API works for scoped or global applications.

    Scoped XMLDocument2 - getFirstNode(String xPath)

    Gets the first node in the specified xPath.

    This method only supports a subset of predicate xPath expressions. For example, assume the following document:
    <store> 
    <resources company="ABC Inc"> 
        <resources type="servers" /> 
    </resources> 
    <resources company="XYZ Inc"> 
        <resource type="bookstore"> 
            <book> 
                <title>Windows</title> 
                <price>10</price> 
            </book> 
            <book year="2009"> 
                <title>Harry Potter</title> 
                <price>50</price> 
            </book> 
            <book year="1999"> 
                <title>Learning XML</title> 
                <price>120</price> 
            </book> 
            <book year="2019"> 
                <title>Learning Java</title> 
                <price>99</price> 
            </book> 
        </resource> 
    </resources> 
</store>
    This method supports the following xPath expressions with predicates:
    "/store/resources/resource[@type='bookstore']/book[@year='1999']", 
"/store/resources/resource[@type='bookstore']/book[@year]", 
"/store/resources/resource[@type='bookstore']/book[price > 100]"
    However, it does not support the following xPath expressions with predicates:
    "/store/resources/resource[@type='bookstore']/book[2]", 
"/store/resources/resource[@type='bookstore']/book[last()]", 
"/store/resources/resource[@type='bookstore']/book[position()>2]"

    To work around this, use xPath without predicates, such as "/store/resources/resource[@type='bookstore']/book") and then filter the nodes in the script using the getFirstNode() and getNextNode() methods.

    표 9. Parameters
    Name Type Description
    xPath String The xPath to obtain the node from.
    표 10. Returns
    Type Description
    XMLNode The first node. 
    var xmlString = "<test>" +
  "  <one>" +
  "    <two att=\"xxx\">abcd1234</two>" +
  "    <three boo=\"yah\" att=\"yyy\">1234abcd</three>" +
  "    <two>another</two>" +
  "  </one>" +
  "  <number>1234</number>" +
  "</test>";
var xmlDoc = new XMLDocument2();
xmlDoc.parseXML(xmlString);
var foo = xmlDoc.getFirstNode('/test/one/two');
gs.info(foo.getTextContent());
    Output:
    abcd1234

    Scoped XMLDocument2 - getNextNode(Object current)

    Gets the node after the specified node.

    표 11. Parameters
    Name Type Description
    current Object The current node.
    표 12. Returns
    Type Description
    XMLNode The next node.

    Output:

another

    Scoped XMLDocument2 - getNode(String xPath)

    Gets the node specified in the xPath.

    주:
    This method is intended for use with small documents since it parses the entire document to match the xPath expression. If the document is too large, an out of memory error may occur. For large documents, use the getFirstNode(String xPath) and getNextNode(Object current) methods, which are designed to stream through the document without parsing the entire document.
    표 13. Parameters
    Name Type Description
    xPath String xPath of the node to obtain.
    표 14. Returns
    Type Description
    XMLNode Current XML node.

 * Checks if given node indeed of given tag.
 * Params:
 *  tag - String, name of tag to check
 *  node - XMLNode, node in which to check for the tag
 * Returns:

    Scoped XMLDocument2 - setEnableCDATAReporting(Boolean enable)

    Sets whether nodes are treated as CDATA or regular text after parsing. CDATA reporting is deactivated by default.

    This method must be called with Scoped XMLDocument2 - parseXML(String xmlDoc).

    See also: Scoped XMLNode - isCDATANode().

    표 21. Parameters
    Name Type Description
    enable Boolean Flag that indicates whether to handle CDATA nodes as CDATA or regular text nodes.
    Valid values:
    • true: Enable CDATA reporting.
    • false: Handle CDATA nodes as regular text nodes after parsing and concatenate it with the adjacent text.

    Default: False
    표 22. Returns
    Type Description
    None

    The following example shows how CDATA is parsed in an element with CDATA reporting activated. The result of content.getFirstChild() is an element that holds the text value another. This element internally contains the information identifying it as a CDATA type. The result of content.getLastChild() is an element that holds the text value element. This element internally contains the information as a text type.

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

    Output:

    another
element
    주:
    Without CDATA reporting activated in the example, the entire child concatenates the CDATA as text with the rest of the text (element) in each line as follows:
    anotherelement
anotherelement

    Scoped XMLDocument2 - setNamespaceAware(Boolean aware)

    When set to true, the XMLDocument2 object processes the document with XML namespaces.

    If you don't set this, an XML document with namespaces won't be enumerated correctly, and an XPath search would fail. 

    표 23. Parameters
    Name Type Description
    aware Boolean When true, the XMLDocument2 object processes the document with XML namespaces.
    표 24. Returns
    Type Description
    void
