Getting value of an attribute using getNodesByXPath

[dcramer]

Hi there,
This is probably simple, but I'm obviously missing something. I want to grab the value of the id of the nearest ancestor that has an id. I'm using getNodesByXPath and think I'm getting the id I want:

[code]var rng = ActiveDocument.Range;
var nd = rng.ContainerNode;
var id = nd.getNodesByXPath('ancestor-or-self::*[@id][1]/@id');[/code]

id.length is 1 and id.item(0).nodeName is 'id', so that looks good, but id.item(0).data is undefined.

What should I be doing?

Thanks,
David

David, try this:

[code]//XMetaL Script Language JScript:
var rng = ActiveDocument.Range;
var nd = rng.ContainerNode;
var id = nd.getNodesByXPath('ancestor-or-self::*[@id][1]/@id');
if(id.length > 0) {
Application.Alert(“Node Name: ” + id.item(0).nodeName);
Application.Alert(“Node Value: ” + id.item(0).nodeValue);
}[/code]

Ok, I see, in the example for getNodesByXpath “.data” is used because it's getting the value of a text node:

[code] tableOfContents += currTitleNumber + “. ” + title.childNodes.item(0).data + “n”;
[/code]

Thanks,
David
