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

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

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 :

http://www.w3schools.com/xpath/default.asp

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


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.

I refined my attempt a little further, and the following code does seem to work, however it has 2 major problems: 1. Very limited support for XPath features Basic paths are supported for elements, attributes, ".", and "..", plus also the "" predicate format is supported - however, only one predicate per path step is supported, and expr must be a relative path. 2. Poor performance

VB6, MSXML 3.2 installed: Q1. I am having a problem selecting nodes with XPATH expressions when an attribute values contain backslashes (\\) in as part of its value: For example the following statement fails to find a node (even though one exists in the XML) if the value of the LDAPServerURL attribute is \\LocalServer but works if the value is "LocalServer".

Hi, I am using XPath to retrieve the node data from an XML file. I used the following code to extract the attribute data from the file. I manually entered the attribute name in the code and I am able to extract the data properly. But when I tried to read the attribute name into a variable and use this variablename instead of actual data it is giving me errors.
