WebService output > Tab-separated text?

Hi all,

I'm receiving output from a webservice formatted as follows:

The number of records can be very large. I need to transform this to a tab-
separated text file within an ASP script. At the moment I go about this as
follows (all code below is JScript):

---CODE---
strXML=String(rsXML(0));
oXMLDOM.loadXML(strXML);
oDatanodes=oXMLDOM.getElementsByTagName("Bridgis_DataTable");
strOut+=WriteRows(oDatanodes);
---END---

Where WriteRows is:

---CODE---
function WriteRows(oDataNodes) {
strOut="";
for(i=0;i<oDatanodes.length;i++) {
nRecords++;
aCh=new Array();
oDatanode=oDatanodes.item(i);
nChildren=oDatanode.childNodes.length;
for(j=0;j<nChildren;j++) {
oChild=oDatanode.childNodes.item(j);
aCh.push(oChild.text);
}
strOut+=aCh.join("\t")+"\n";
}
return strOut;
}
---END---

This is a very expensive operation which is not acceptable because the XML
recordsets i get are very large (can be up to 1,000,000 records), so I am
looking to implement a more efficient way to do this. I'm thinking about
XSLT but don't know how I would integrate this into my ASP script. Any
ideas?

Thanks,
Martijn

Hi,

XSLT seems a bad idea in this case, I doubt if it would more efficient. The fastest way to do it is probably by ignoring the fact that it is XML and handling it as plain text.
