XPath works in XML Spy, but not in javascript node.selectSingleNode

[iporter]

Hi, thanks in advance for any help. I have an xml file and use javascript/XPath to pull data to an HTML page. In XML Spy, using XPath evaluator, the below XPath returns the appropriate value. However, in the browser, I get 'object required'.


First, I select a single level1 node based on it's id attribute, using

var node = nodes.selectSingleNode("//root/level1[@id=1]");

This works fine. Next I try to select a single node's value from within that node, using

innerNodeVal = node.selectSingleNode("//level1/level2/level3/level4[@id=1]/wanted node").text;

Any thoughts? Putting just 1 slash or 0 slashes at the beginning of the XPath string doesn't solve it, but all work in XML Spy.

Thanks again,
Iain

When you evaluate the x-path in Spy, it is taken from the root-node.
However, in the script function, you take it from the context of node. (being: //root/level1[@id=1] )
So: take it from level1.
innerNodeVal = node.selectSingleNode("level2/level3/level4[@id=1]/wanted node").text;
