Question

Example:

 <div class='known' name='unknown'>

How can I return name attribute value (‘unknown’) based on known class attribure value, with XPath 1.0?

While looking for an answer I found that XPath 2.0 has instrument for this:

 //div[@class='known']/@name/string()

But can’t find XPath 1.0 analogy

Answer 1

Use:

string(//div[@class='known']/@name)

This produces the string value of the name attribute of the first in document order div element such that the string value of its class attribute is "unknown".

If //div[@class='known'] selects more than one div element and you want the value of the name attribute for the k-th selected div, use:

string((//div[@class='known'])[$k]/@name)

where $k has to be substituted with the wanted integer, or otherwise the variable $k must be in the evaluation context for the XPath expression.
