Perl XPath : How to get the value of the attribute?

[Abhinav]

Hi,

I have the following XML :

<checkIn bug="1111111">
<regression>
</regression>
</checkIn>

How do i get the value "1111111" for bug ?

I am able to get everything under <checkIn> using

my $bug = $xPath->find("/checkIn[\@bug]");

TIA

my $bug = $xPath->find("/checkIn[\@bug]");

I don't use Perl, but the XPath should be
/checkIn/@bug

Thanks. That Worked !

I guess the extra / allows me to fetch only the node containing the
attribute ?

Any docs (apart from the CPAN XPath docs) which detail these concepts more
clearly ?

TIA

Google is your friend :

And the official W3C reccomendation :

No, it selects the attribute node itself,
/checkIn
selects the <checkIn> root element,
/checkIn/@*
selects all its attribute nodes, and
/checkIn/@bug
selects the attribute with name bug

There is the XPath 1.0 specification:
http://www.w3.org/TR/xpath
And there are tutorials, see
http://www.w3schools.com/xpath/default.asp
for instance.
