in reply to Using the XML::Parser Module

Another option is XML::GDOME, which, apart from a slightly outdated install process, seems to work well. And has XPath support out of the box. Again another case of the thin perl wrapper around the speedy C implementation. Doco is complete, but it doesnt hold anyones hand - if you know XML reasonably well, you should be fine - if your not familiar with the XML concepts, finding what you need can be difficult.

#!/usr/bin/perl -w use strict; use XML::GDOME; my $fname = '/path/to/your.xml'; my $doc = XML::GDOME->createDocFromURI($fname,GDOME_LOAD_SUBSTITUTE_EN +TITIES); # or whatever gdome options float your boat my @nodes = $doc->findnodes('/xpath/to/required/element'); foreach my $node (@nodes) { if (needToUpdateAttribute($node)) { my $attributeName = getRequiredAttrName(...); my $newValue = getNewAttrValue(...); $node->setAttribute($attributeName, $newValue); } }
