Jscript variable in XPath expression

[j_kowalska]

Hi, I'm new to XPath

Could anybody tell me how to use Jscript variable in XPath expression?

In the folowwing code I get an error ' object required':
....
var selectedCustomer =
XDocument.DOM.selectSingleNode("/my:mojePola/my:Customer").text

var selectedNode =
doc.selectSingleNode("/dfs:myFields/dfs:dataFields/dfs:Kontakty[@Nazwisko
= selectedCustomer]")
....
when I replace selectedCustomer (in the second line) with a string,
e.g.
....
var selectedNode =
doc.selectSingleNode("/dfs:myFields/dfs:dataFields/dfs:Kontakty[@Nazwisko
='somestring' ]")
....
everything is OK.

Any hints appreciated,

Your problem might be in another area than where you think it is, but to use
the variable in the expression try this:

var selectedNode =
doc.selectSingleNode("/dfs:myFields/dfs:dataFields/dfs:Kontakty[@Nazwisko
= '" + selectedCustomer + "']")

If this doesn't solve the error, your problem is probably in one of the
XPAth expressions you have used. The XML nodes are not being found, so you'll
need to debug your XPath expression to find the correct one to the XML nodes
you want to find.
