How to use variables in document.evalua te()

[shellon]

Hi all:
I met a problem when using document.evalua te() to get text content
using XPath,
my code is as follows:

nodes = document.evalua te("/html/body/div/ul[1]/li[5]", document,
null,XPathResul t. UNORDERED_NODE_ SNAPSHOT_TYPE , null);

in the XPath expression "/html/body/div/ul[1]/li[5]", I need to
traverse from li[1] to li[5],
so I should use a variable here , like this:

for (index =1; index<6; i++)
{
nodes = document.evalua te("/html/body/div/ul[1]/li[index]", ....);
// the variable index here is invalid!
}
my question is: How to use the variable in XPath expression?
appreciate your help!

Hi

You may be confusing this with something like PHP which does allow you
to reference a variable within a string literal.

In JavaScript it should be

nodes = document.evalua te("/html/body/div/ul[1]/li[" + index+ "]",
.....);
