Declaration

Source position: laz2_xmlcfg.pas line 93

protected function TXMLConfig.InternalFindNode(

  const APath: string;

  PathLen: Integer;

  CreateNodes: Boolean = False

):TDOMNode;

Arguments

APath

  

Path specifier for the DOM node.

PathLen

  

Length of the path specifier.

CreateNodes

  

Indicates if missing DOM nodes in Document are created.

Function result

DOM node located for the specified path.

Description

InternalFindNode is a TDOMNode function used to locate the node stored at the path specified in Document. InternalFindNode ensures that the node cache for the class is updated to include the TDOMNode at APath when it is accessed in the method. It also ensures that all element nodes for the specifier in APath are included in the cache as well. The FindChildNode method is used to locate TDOMNodes in the hierarchy. When CreateNodes is True, any missing DOM nodes in the hierarchy are created.

InternalFindNode is used in the implementation of the GetValue, SetValue, GetListItemCount, DeletePath, and FindNode methods.
