Getting the XML node containing a search text...

[biswanath_c]

Hi

I am trying to write a perl script that'd give me the list of nodes in an XML doc that contain a search string. What's the best way to achieve this goal? I'd prefer getting the XPaths of the nodes that contain the search string.

Can you be more specific regarding what you want to search? Are you trying to match only element names? Element text? Attribute names? Attribute values? All of the above?

You should post a tiny sample of your XML and the search string.

XML::Twig has xpath capabilities.

given a string, I would want to search for all nodes in a an XML document that 'contain' the search string 'in' its value (not exact match). So, i want to search for nodes whose 'value' contain a given search string and would like to get the xpath of all such matching nodes.

Using XML::LibXML this works for me

use strict;
use XML::LibXML;

#Parse XML
my $template = 'xmlsample.xml';
my $parser = XML::LibXML->new();
my $doc = $parser->parse_file($template);

#Search all text nodes
for my $node ($doc->findnodes( '//text()' ))
#Print xpaths if criteria matched
  {my $search = $node->nodeValue;
      if ($search =~ m/InsertSearchCriteriaHere/)
        {print $node->nodePath();}
  }
