RemoveElement Method

Removes the elment as the specified XPath.

Object Oriented Interface

public function doRemoveElement();

Procedural Interface

ipworks_xml_do_removeelement($res);

Remarks

This method removes the element specified by XPath.

When called the class will remove the element and its children from the internal representation of the XML (the DOM). This may be used at any time after Parse returns, or from within the EndElement event as a document is parsed in order to remove sections of a document that will not be needed later. By removing unnecessary elements from the DOM memory consumption is reduced and overall performance is improved.

RemoveElement Example:

Given the XML

<food>
	<fruits>
		<apple>
			<color>red</color>
		</apple>
		<banana>
			<color>yellow</color>
		</banana>
	</fruits>
</food>

This code removes the apple element and its children.

xml.XPath = "/food/fruits/apple";
xml.RemoveElement(); 

The XML stored in the DOM is now:

<food>
	<fruits>
		<banana>
			<color>yellow</color>
		</banana>
	</fruits>
</food>
