Using Xpath string functions in a XPath Extractor

Hi,

I need some help in extracting a string from a HTML response and  I'm using
an XPath Extractor for it.

Example:

The HTML response has the following sample content:

<html>
...
...
<input type="hidden" name="questionVersionId" value="10"
id="questionVersionId"/>
...
<input type="hidden" name="5D70C96B-BA07-4FB4-AAB7-65788B4E4FE3_md5"
value="AD0234829205B9033196BA818F7A872B"
id="5D70C96B-BA07-4FB4-AAB7-65788B4E4FE3_md5"  />
...
</html

and i need to extract only the name attribute from the input field that
ends-with "_md5" (5D70C96B-BA07-4FB4-AAB7-65788B4E4FE3_md5) and  value
attribute  that has 32 characters (AD0234829205B9033196BA818F7A872B)

To extract the name attribute i used the XPath expression:
*ends-with(//input[@type='hidden']/@name, "_md5")*

and to extract the value attribute i used the XPath expression:
*//input[@type='hidden']/string-length(@value)=32*

Both of these expressions are not returning the required results.

I'm sorry as this question is not much related to JMeter, but i have posted
this question after i got exhausted of googling.

Thanks in advance.

Regards
Prasanna

I figured it out!!

//input[@type="hidden" and contains(@name,"md5")]/@name
//input[@type="hidden" and contains(@name,"md5")]/@value

Thanks,
Prasanna
