Hello,
I searched throught perldoc XML::Xpath and here what it has to say:
--------------------------------------------
findvalue($path, [$context]) Returns either a "XML::XPath::Literal", a "XML::XPath::Boolean" or a
"XML::XPath::Number" object. If the path returns a NodeSet, $node-
set->to_literal is called automatically for you (and thus a
"XML::XPath::Literal" is returned). Note that for each of the objects
stringification is overloaded, so you can just print the value found,
or manipulate it in the ways you would a normal perl value (e.g. using
regular expressions).
----------------------------------------------
But I am not able to get the numeric value as return value in following
code snippet. 123 $loopcount = $mail->findvalue('loopcount')->value();
124 if($loopcount == 0) {$loopcount = 1};I get this error when I removed the quotes around findvalue call.
------------------------------------------- Argument "" isn't numeric in numeric eq (==) at ./gencap.pl line 124. --------------------------------------------
How do I go about this?
Thanks and Regards, Manish

Hi List, How do i convert a string variable returned by some XPath API into a number so that I can compare it or loop using this number.
I am reading one number from XML and I want to use it for looping.
In general, conversion from a string to a number is transparent in Perl. "4" is the same as 4.
