JAVASCRIPT selectNodes() returns 0 if XML contains '&' char

Arindam Tewary

Hi , I want to parse XML values in javascript. The problem is if XML values does not have either of '&' char, thing working nicely.

<DataSet>
<Row>
<NDOCUMENTID>499</NDOCUMENTID>
<TDESCRIPTION>my god</TDESCRIPTION>
<TDISPLAYNAME>my god</TDISPLAYNAME>
<TTITLE>my god</TTITLE>
<NPARENT_DOC_ID>0</NPARENT_DOC_ID>
<NPARENT_FOLDER_ID>496</NPARENT_FOLDER_ID>
</Row>
<Row>
<NDOCUMENTID>501</NDOCUMENTID>
<TDESCRIPTION>Level 2Folder</TDESCRIPTION>
<TDISPLAYNAME>Level 2Folder</TDISPLAYNAME>
<TTITLE>Level 2Folder</TTITLE>
<NPARENT_DOC_ID>0</NPARENT_DOC_ID>
<NPARENT_FOLDER_ID>500</NPARENT_FOLDER_ID>
</Row>
</DataSet>

but if '&' is present then 'selectNodes' function does not select any row.

<DataSet>
<Row>
<NDOCUMENTID>499</NDOCUMENTID>
<TDESCRIPTION>my **&**amp; god</TDESCRIPTION>
<TDISPLAYNAME>my god</TDISPLAYNAME>
<TTITLE>my god</TTITLE>
<NPARENT_DOC_ID>0</NPARENT_DOC_ID>
<NPARENT_FOLDER_ID>496</NPARENT_FOLDER_ID>
</Row>
<Row>
<NDOCUMENTID>501</NDOCUMENTID>
<TDESCRIPTION>Level 2Folder</TDESCRIPTION>
<TDISPLAYNAME>Level 2Folder</TDISPLAYNAME>
<TTITLE>Level 2Folder</TTITLE>
<NPARENT_DOC_ID>0</NPARENT_DOC_ID>
<NPARENT_FOLDER_ID>500</NPARENT_FOLDER_ID>
</Row>
</DataSet>

Any help is appreciated. Thanks in advance. follong is my javascript code which I am using for parsing XML.

        var objSelection;
        var sFolderName, sFolderID;
        var objFolderNodes;
        var nSelectedValue = 0;
        var objXML = new ActiveXObject("MSXML2.DomDocument");

        objXML.loadXML(sXML);
