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 - Pyxie for a description of Pyxie

Personal notes

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

    You missed something... It also comes with another tool: pyxhtml So converting HTML to XHTML is as easy as: pyxhtml myfile.html | pyxw > myfile.xhtml Matt.
