Using Xpath Extractor how to fetch the particular value

[Arumugam Vallimuthu]

Hi,

I am new to Jmeter. I am facing some issues while fetching the data 
while using Xpath Extractor.

<td colspan="2" align="left">
   <a href="/pdownload.do?target=100444-76&method=hs">HTTP</a>&nbsp; 

 </td>


I want to fetch the specific data:

*/pdownload.do?target=100444-76&method=hs*

For getting this url I have used the following Xpath query : *//a[text() 
= 'HTTP']/@href

*and I used Tidy and Reference Name is : Patchdownload

Actually the same kind of link is displayed in the application 2 times. 
That link was

<a href="/pdownload.do?target=100444-76&method=h">HTTP</a>&nbsp; 

But our script is taking the first value. How can I specifically say to 
jmeter  to fetch the 2 nd displaying value?

Thanks in Advance.

Regards
Aru
