XmlNode Class Methods

Add methods create a new node of the specific type, append this new node to the child list, and return this newly created node, while Insert methods add the node to the specified position.

In this section, we discuss the XmlNode methods. The methods are discussed in alphabetical order.

Syntax

AddAttribute(Name, Value);

Description

Use the AddAttribute method to add an attribute to an XmlNode. A reference to the newly created attribute is returned.

If you specify an attribute name that already exists, the new value you use replaces the existing value, and a reference to the attribute is returned.

Attributes added by the AddAttribute method appear in an arbitrary order in the generated XML.

Parameters

Field or Control	Definition
`Name`	Specify the name of the Attribute that you want to create, as a string.
`Value`	Specify the value of the Attribute that you want to create, as a string.

Returns

None.

Example

Here is a set of XML response code.

<?xml version="1.0"?> 
<myroot> 
   <postreqresponse> 
      <candidate> 
         <user> 
            <location scenery="great" density="low" blank="eh?"/> 
            
         </user> 
      </candidate> 
   </postreqresponse> 
</myroot>

Here's the PeopleCode that builds it.

Local XmlDoc &inXMLDoc;
Local XmlNode &postReqNode;
Local XmlNode &candidatesNode;
Local XmlNode &userNode;
Local XmlNode &locationNode;
Local XmlNode &sceneryAtt;
Local XmlNode &densityAtt;
Local XmlNode &blankAtt;
Local boolean &ret;

&inXMLDoc = CreateXmlDoc("<?xml version='1.0'?><myroot/>");

&postReqNode = &inXMLDoc.DocumentElement.AddElement("postreqresponse");
&candidatesNode = &postReqNode.AddElement("candidates");
&userNode = &candidatesNode.AddElement("user");
&locationNode = &userNode.AddElement("location");

&locationNode.AddAttribute("scenery", "great");
&locationNode.AddAttribute("density", "low");
&locationNode.AddAttribute("blank", "eh?");

Syntax

AddAttributeNS(NamespaceURI, AttributeName, Value)

where NamespaceURI can have one of the following forms:

URL.URLname

&childNode.AddAttributeNS("http://www.peoplesoft.com", "scenery", "great");

Syntax

AddCDataSection(Data)

Description

Use the AddCDataSection to add a CDATA section to an XmlNode.

CDATA sections may occur anywhere character data may occur; they are used to escape blocks of text containing characters which would otherwise be recognized as markup.

To insert a CDATA section at a particular place in the list of nodes, use the InsertCDataSection method instead.

A reference to the newly created CDATA section is returned.

Note: You cannot use this method with a SoapDoc object.

Syntax

InsertNode(&NewNode, {&RefNode | Position})

Description

Use the InsertNode method to insert a new node. The node is inserted either before the node specified by &RefNode, or at the location specified by Position.

&NewNode refers to an already instantiated XmlNode object. You must create the node before you can insert it.

&RefNode refers to an already instantiated XmlNode object.

Parameters

Field or Control	Definition
`&NewNode`	Specify the name of an already instantiated XmlNode that you want to insert.
`&RefNode` \| `Position`	Specify either the name of an existing node or the location where you want the node to be inserted.

Returns

A reference to the newly inserted node.

Example

The following PeopleCode program inserts a node using a position:

Local XmlDoc &inXMLDoc, &firstDoc;
Local XmlNode &childNode;

&firstDoc = CreateXmlDoc("<?xml version='1.0'?><myroot><third><child/></third></myroot>");
&inXMLDoc = CreateXmlDoc("<?xml version='1.0'?><root><first/><second/></root>");
&childNode = &firstDoc.DocumentElement.FindNode("third");

&inXMLDoc.DocumentElement.InsertNode(&childNode, 2);

The following PeopleCode program inserts a node using a reference node:

Local XmlDoc &inXMLDoc, &firstDoc;
Local XmlNode &childNode, &secondNode;

&firstDoc = CreateXmlDoc("<?xml version='1.0'?><myroot><third><child/></third></myroot>");
&inXMLDoc = CreateXmlDoc("<?xml version='1.0'?><root><first/><second/></root>");
&childNode = &firstDoc.DocumentElement.FindNode("third");
&secondNode = &inXMLDoc.DocumentElement.FindNode("second");

&inXMLDoc.DocumentElement.InsertNode(&childNode, &secondNode);

The following is the XML document before the insert:

<?xml version="1.0"?>
<root>
  <first/>
  <second/>
</root>

The following is the XML document after the insert:

<?xml version="1.0"?>
<root>
  <first/>
  <third>
    <child/>
  </third>
  <second/>
</root>

Syntax

InsertProcessInstruction(Target, Data, Position)

Description

Use the InsertProcessInstruction method to insert a processing instruction to an XmlNode at the location specified by Position.

Note: Youcannot use this method with a SoapDoc object.

Parameters

Field or Control	Definition
`Target`	Specify the application to which the instruction is directed, as a string.
`Data`	Specify the data to be used with the instruction.
`Position`	Specify where you want to insert the process instruction, as a number.

Returns

A reference to the newly created processing instruction.

Example

For example:

Local XmlDoc &inXMLDoc;
Local XmlNode &procInst;

&inXMLDoc = CreateXmlDoc("<?xml version='1.0'?><root/>");
&procInst = &inXMLDoc.DocumentElement.AddProcessInstruction("first", "firstvalue");
&procInst = &inXMLDoc.DocumentElement.AddProcessInstruction("second", "secondvalue");

&procInst = &inXMLDoc.DocumentElement.InsertProcessInstruction("third", "thirdvalue", 2);

This is the XML document before the insert:

<?xml version="1.0"?>
<root>
  <?first firstvalue?>
  <?second secondvalue?>
</root>

This is the XML document after the inser:

<?xml version="1.0"?>
<root>
  <?first firstvalue?>
  <?third thirdvalue?>
  <?second secondvalue?>
</root>

Syntax

InsertText(Data, Position)

Description

Use the InsertText method to insert a text node. The node is inserted at the location indicated by Position.

Note: A text node is not the same as a text declaration. The text declaration is added automatically with the CreateXmlDoc function. A text node just contains text within an XmlDoc.

Parameters

Field or Control	Definition
`Data`	Specify the data to be used for the text node, as a string.
`Position`	Specify where you want to insert the text ndoe, as a number.

Returns

A reference to the newly created text node.

Example

For example:

Local XmlDoc &inXMLDoc;
Local XmlNode &textNode;

&inXMLDoc = CreateXmlDoc("<?xml version='1.0'?><root/>");
&textNode = &inXMLDoc.DocumentElement.AddText("first text");
&textNode = &inXMLDoc.DocumentElement.AddText("second text");

&textNode = &inXMLDoc.DocumentElement.InsertText("third text", 2);

This is the XML document before the insert:

<?xml version="1.0"?>
<root>
first textsecond text</root>

This is the XML document after the insert:

<?xml version="1.0"?>
<root>
first textthird textsecond text</root>

Syntax

RemoveAllChildNode()

Description

Use the RemoveAllChildNode method to remove all child nodes for an XmlNode.

Parameters

None.

Returns

None.

Example

For example:

Local XmlDoc &inXMLDoc;
Local XmlNode &elementNode;

&inXMLDoc = CreateXmlDoc("<?xml version='1.0'?><root/>");
&elementNode = &inXMLDoc.DocumentElement.AddElement("first");
&elementNode = &inXMLDoc.DocumentElement.AddElement("second");
&elementNode = &inXMLDoc.DocumentElement.AddElement("third");

&inXMLDoc.DocumentElement.RemoveAllChildNode();

This is the XML document before the removal:

<?xml version="1.0"?>
<root>
  <first/>
  <second/>
  <third/>
</root>

This is the XML document after the removal:

<?xml version="1.0"?>
<root/>

Syntax

RemoveChildNode({Position | Node})

Description

Use the RemoveChildNode method to remove the child node in an XmlNode specified by Node, or located at Position.

Parameters

Field or Control	Definition
`Position` \| `Node`	Specify the child node that you want to delete, either using its position number or its name.

Returns

A reference to the removed XmlNode.

Example

The following PeopleCode program uses a position:

Local XmlDoc &inXMLDoc;
Local XmlNode &elementNode, &removedNode;

&inXMLDoc = CreateXmlDoc("<?xml version='1.0'?><root/>");
&elementNode = &inXMLDoc.DocumentElement.AddElement("first");
&elementNode = &inXMLDoc.DocumentElement.AddElement("second");
&elementNode = &inXMLDoc.DocumentElement.AddElement("third");

&removedNode = &inXMLDoc.DocumentElement.RemoveChildNode(2);

The following PeopleCode program uses a reference node:

Local XmlDoc &inXMLDoc;
Local XmlNode &elementNode, &removedNode;

&inXMLDoc = CreateXmlDoc("<?xml version='1.0'?><root/>");
&elementNode = &inXMLDoc.DocumentElement.AddElement("first");
&elementNode = &inXMLDoc.DocumentElement.AddElement("second");
&elementNode = &inXMLDoc.DocumentElement.AddElement("third");

&elementNode = &inXMLDoc.DocumentElement.FindNode("/second");
&removedNode = &inXMLDoc.DocumentElement.RemoveChildNode(&elementNode);

This is the XML document before the removal:

<?xml version="1.0"?>
<root>
  <first/>
  <second/>
  <third/>
</root>

This is XML document after the removal:

<?xml version="1.0"?>
