Capturing name in source page using xpath in python

Question

I have the following url source page:

<input type="hidden" name="QQQ" value="AAA" />
<input type="hidden" name="WWW" value="BBB" />
<input type="hidden" name="EEE" value="CCC" />
<input type="hidden" name="WANTED" value="DDD" />

I want to extract WANTED where the value is DDD from that. What I tried is:

token=tree.xpath('//input[@type="hidden"]/input[@value="DDD"]/@name')

but it gives me QQQ

you want the name attribut of what ? the first input node? the last input node ? It's unclear how you find "WANTED" — flafoux, May 12 '15 at 11:37

then you should replace `DDD` with `1`. – Joel M. Lamsen May 12 '15 at 11:49
try removing the quotes for it to represent a number. something like `[@value=1]` – Joel M. Lamsen May 12 '15 at 11:51

@MortezaLSC This is rather pointless, if you do not show the _actual_ input document. Please edit your question and show the document you are really working on. Oh, and also show a _complete_ Python script instead of a single line. – Mathias Müller May 12 '15 at 11:55
