XPathScript =========== ===== DESCRIPTION This is the XML::XPathScript stylesheet framework, part of the AxKit project at http://axkit.org/. XPathScript is a stylesheet language similar in many ways to XSLT (in concept, not in appearance), for transforming XML from one format to another - possibly HTML, but XPathScript also shines for non-XML-like output. Like XSLT, XPathScript offers a dialect to mix verbatim portions of documents and code. Also like XSLT, it leverages the powerful ``templates/apply-templates'' and ``cascading stylesheets'' design patterns, that greatly simplify the design of stylesheets for programmers. The availability of the XPath query language inside stylesheets promotes the use of a purely document-dependent, side-effect-free coding style. But unlike XSLT which uses its own dedicated control language with an XML-compliant syntax, XPathScript uses Perl which is terse and highly extendable. The result of the merge is an extremely powerful tool for rendering complex XML documents into other formats. Stylesheets written in XPathScript are very easy to create, extend and reuse, even if they manage hundreds of different XML tags. As a testimony to these qualities, XML::XPathScript comes bundled with a fairly comprehensive stylesheet for converting Docbook XML into LaTeX (in the examples/ directory). ===== INSTALLATION To install this module type the following: perl ./Build.PL ./Build ./Build test ./Build install or, if you are old-school, perl Makefile.PL make make test make install During installation, Build.PL will check if it should use XML::LibXML or XML::XPath as the default xml parser. If you want to force XPathScript to use one or the other, do perl Build.PL -parser=XML::LibXML or perl Build.PL -parser=XML::XPath If AxKit or TomKit are present, their respective XPathScript processors will be automatically added to the installation. To force their installation without the presence of AxKit/TomKit, do perl Build.PL -axkit -tomkit ===== COMMAND-LINE USE This module provides an xpathscript(1) shell command that comes with its own manpage. ===== SUPPORT FOR AXKIT XPS comes with its AxKit language module. Not to clash with the Apache::AxKit::Language::XPathScript.pm bundled with AxKit, it is named Apache::AxKit::Language::YPathScript.pm. To use this module under AxKit, add the following to your httpd.conf (the first two lines are probably already present): PerlModule AxKit AddHandler AxKit .xml AxAddStyleMap application/x-ypathscript Apache::AxKit::Language::YPathScript And to your .htaccess something like: <AxStyleName "#default"> AxAddProcessor application/x-ypathscript your_stylesheet.xps </AxStyleName> ===== SUPPORT FOR TOMKIT XPS also includes a TomKit processor, which will be installed if TomKit itself is detected. To use the processor, add something like the following to your .htaccess: PerlSetVar AxAddProcessorMap "text/xps=>Apache2::TomKit::Processor::XPathScript" <Files *\.xml> PerlFixupHandler Apache2::TomKit PerlSetVar AxAddProcessorDef "text/xps=>stylesheet.xps" </Files>
