GetNode method: Incoming Business Interlink class

Syntax

GetNode({nodename | nodenumber})

Description

The GetNode method returns a BiDocs reference to a child XML node (element or comment). Use the GetNode method upon a BiDocs reference to an XML element to access the child nodes for that element.

Parameters

Parameter	Description
nodenumber | nodename	Specify the node that you want to reference. You can specify either a node number (the first node is 1, the second 2, and so on) or a node name (that is, the XML tag.)

Returns

BiDocs. The returned XML element within a BiDocs object.

Example

Here is a set of XML request code.

<?xml version="1.0"?> 
   <postreq> 
      <email>[e-mail]</email> <projtitle> 
         <projsubtitle>first_subtitle</projsubtitle> 
         <projsubtitle>second_subtitle</projsubtitle> <projsubtitle>third_subtitle</projsubtitle> 
      </projtitle> 
   </postreq>

Here is the PeopleCode that gets the postreqDoc element and the projtitle element.

Local BIDocs &rootInDoc, &postreqDoc, &projtitleDoc; 
Local string &name, &blob; 
&blob = %Request.GetContentBody(); 
&rootInDoc = GetBiDoc(&blob); 
&postreqDoc = &rootInDoc.GetNode("postreq"); 
&projtitleDoc = &postreqDoc.GetNode("projtitle");

Here is the PeopleCode that gets the postreqDoc element, the projtitle element, and the third projsubtitle element.

Local BIDocs &rootInDoc, &postreqDoc, &projtitleDoc, &projsubtitleDoc; 
Local string &name, &blob; 
&blob = %Request.GetContentBody(); 
&rootInDoc = GetBiDoc(&blob); 
&postreqDoc = &rootInDoc.GetNode(1); 
&projtitleDoc = &postreqDoc.GetNode(2); 
&projsubtitleDoc = &projtitleDoc.GetNode(3);

To parse a list of elements like <projsubtitle>, where elements have the same name, you must call GetNode using an index number rather than the element name.
