Search node in IXMLDOMDocument
-
Hi, I need a 'find method' which returns a node in a IXMLDOMDocument. Is there any easy way to achieve this? Any tutorials/links about this? Thanks in advance, Jens
You could try here Code Project[^] Or use the CP site search and look for "XML Document Wrapper" for instance. Ant. I'm hard, yet soft.

It had a 'find' function in it, but it's pretty strangely coded that part. When he finds it, he adds it to the root node. Not exactly what i wanted to do with it. It should return a CXMLNode* or NULL if not found.

It was quite a while ago that I looked at that class, I just remembered that there was a
Findimplementation. If it generally finds a node then you ought to be able to change the function to return CXMLNode*.CXMLNode* CXMLNode::Find(CXMLNode* rootNode, LPCTSTR nodeName, LPCTSTR nodeText, LPCTSTR attribName, LPCTSTR attribValue)
Where it adds the node to the root replace
CXMLNode *pNode = new CXMLNode(Nodes[i]);
rootNode->Nodes.Add(pNode);with
return Nodes[i];
And right at the end of the function
Nodes[i]->Find(rootNode,nodeName,nodeText,attribName,attribValue);
}
return NULL;
}For your purposes you will probably not need to pass rootNode to the function and therefore all refrences to it can be removed. Ant. I'm hard, yet soft.

Hi. Is it easy to integrate XPath functions into regular XML files? selectNodes() is not a member function of IXMLDocument for example
JensB wrote: Is it easy to integrate XPath functions into regular XML files? I don't know what you mean. If you are using any parser that supports XPath queries ( MSXML does ) then it is integrated for you. You construct the XPath statement through whatever means is required to solve the current problem. You provide the statement as a text string to the parser engine (with MSXML it is the IXMLDOMDocument::SelectNodes() and SelectSingleNodes() methods) and it returns a node list of all nodes matching the XPath statement. JensB wrote: selectNodes() is not a member function of IXMLDocument for example It is a member of IXMLDOMDocument. It inherits that method as well as selectSingleNode() from the IXMLDOMNode interface. That allows you to execute relative XPath statements. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/xmlsdk/html/xmmthselectnodes.asp[^]
