>                 Key: XERCESC-1788
>                 URL: https://issues.apache.org/jira/browse/XERCESC-1788
>             Project: Xerces-C++
>          Issue Type: Bug
>          Components: DOM
>    Affects Versions: 2.7.0
>         Environment: Windows XP, VC++ 6
>            Reporter: Sanish Kanjany
>            Priority: Major

> I have been using xerces-c2.2 for a long and now moved to xerces-c2.7. I was 
> using deprecated DOM_Parser(with 2.2) and now using XercesDOMParser(with 2.7) 
> itself. I had to write some wrappers for DOMNode, DOMDocument, DOMNodeList 
> etc to avoid changes in my existing code as DOM_Node, DOM_Document, 
> DOM_NodeList etc. I could see the parsing time is significantly reduced with 
> xerces-2.7.  But some APIs to the parser is getting slow down. 
> For example,  in the function given below, to  get all element children of a 
> node, is very slow when the reference node has a large number of child nodes. 
> The function spends more time inside the for loop. The same function is very 
> fast with old version of xerces-c(2.2).
> bool CMyDomParser::GetAllChildNodes(DOM_Node node, std::vector<DOM_Node>& 
> nodes)
> {
>       nodes.clear();
>       if(node == NULL)
>               return false;
>       DOM_NodeList nodelist = node.getChildNodes();
>       if(nodelist == NULL)
>               return true;
>       bool retval = false;
>       int iLisSize=nodelist.getLength();
>       for(int i=0; i < iLisSize; i++)
>       {
>               DOM_Node oTempNode=nodelist.item(i);
>               if(oTempNode.getNodeType() != DOM_Node::ELEMENT_NODE)
>                       continue;
>               retval = true;
>               nodes.push_back(oTempNode);
>       }
>       return true;
> }
>  What will be the base reason ? 
> Anyadvancement needed in my code?  
> Is there any change in implementation of DOMNodelist ::item(int) ?
> Thanks,
> Sanish
