Item Description: A line-oriended interface to XML
Review Synopsis: The module's main usage is through the pyx, pyxv, pyxw and pyxhtml tools
XML::PYX, based on XML::Parser is the Perl implementation. It comes with 3 tools: pyx (non-validating) and pyxv (validating) output the Pyx version of the document and pyxw writes an XML version of a Pyx flow. See XML.com - Pyxie for a description of Pyxie
XML::TiePYX is easier to use on a Windows system
Pyx is really cool to extract information from an XML file, or to perform simple transformations on simple XML files. The module is mature (it is quite simple so there shouldn't be too many bugs in it). I never actually use the module, only pyx, which I pipe to a perl -n or perl -p script.
Print all the elements used in an XML document, with the number of occurences.
pyx file.xml | perl -n -e '$nb{$1}++ if( m/\A\((.*)\n/); \ END { map { print "$_ used $nb{$_} time(s)\n";} sort keys %nb;}'
Warn in case of duplicate ID:
pyx file.xml | perl -n -e '($id)=( m/^Aid (.*)\n/) or next; print "duplicate id: $id\n" if($id{$id}); $id{$id}=1;'
Change a tag name (class to color):
pyx wine.xml | perl -p -e 's/^([()])class/$1color/' | pyxw
