Re: Push + variable argument

MY.cgi
 my $xslt = XML::LibXSLT->new();
 my $stylesheet = $xslt->parse_stylesheet_file('abc.xsl'); 
 push @xsltParams, ('arg', $str);
 push @xsltParams, ('val', '1');
 my $result = $stylesheet->transform_file('abc.xml', @xsltParams);
 print $stylesheet->output_string($result);

This is how I access in XSL file.

MY.xsl
 <xsl:value-of select="$arg"/>
[download]

Can you please tell more about XPath and how can I access parameters in XSL file passed from cgi file?

I think you're mixing up syntax. From the documentation (modified): `my $results = $stylesheet->transform_file('abc.xml', arg => "$str");` [download] Or more general: `transform_file(filename, %params);` The usage of the Xpath syntax is also explained in the documentation: `$stylesheet->transform($doc, param => "'string'");` Note the `"'` and `'"` ! And where does $str come from and what does it contain? Please put `use strict;` and `use warnings;` in your script.	[reply] [d/l] [select]

Thank you very much all especially dHarry.Now it is working. $str comes from another cgi script and contains values separated by spaces. `$str=$in{'values_separated_by_spaces'};` [download] I am getting values in $str and they are passed to XSL script using XPath mechanism as you told. I want to separate these space values in XSL script so to display individual ones.Can you tell how to do this?	[reply] [d/l]

Do the separating in Perl (for example with the split statement) and pass the individual arguments/parameters to the XSLT. So something like: In the xslt: `<xsl:param name="param_1"/> <xsl:param name="param_2"/>` [download] In the Perl script: `my ($par1, $par2) = split (/ /,$str); my $results = $stylesheet->transform($source, XML::LibXSLT::xpath_to_string(param_1 => $par1), XML::LibXSLT::xpath_to_string(param_2 => $par2) );` [download] NB The utility function xpath_to_string takes care of the quoting. This is probably the better/easier way of doing things. See the documentation for details. See playing with XSLT for a bigger example.	[reply] [d/l] [select]

`<xsl:value-of select="substring-before($arg,' ')"/>` [download] I got this way of separating the values.Now looking for displaying them individually in COMBO box using "<xsl:for each>"	[reply] [d/l]
