Are there any utilities similar to xpath for parsing XML files that would be natively available on a RedHat server?

Similar questions have been answered elsewhere, but none of the tools listed are on the server.

update: xmllint is installed, and man xmllint indicates that it can parse xml files, but it is not clear that this gives me the ability to extract a string from a specific node.

xsltproc (command line interface to libxslt) is always available on RHEL.
usage: xsltproc xsl_stylesheet xml_file.

If, given this XML

$ cat a.xml

You want to be able to do

$ ./xpath //a/b a.xml

then you could just cut & paste this:

$ cat xpath
use strict;
use warnings;
use XML::LibXML;

my $parser = XML::LibXML->new();
my $document = $parser->parse_file($ARGV[1]);
my @nodes = $document->findnodes($ARGV[0]);
for my $node (@nodes) {
  print $node->textContent, "\n";

You should be able to install the XML::LibXML module using perl -MCPAN -e 'install XML::LibXML'

Or just yum install 'perl(XML::LibXML)'. – Ignacio Vazquez-Abrams Apr 5 '11 at 14:28

XMLStarlet is in EPEL.

Try xmllint and the --xpath option:


$ xmllint --xpath '//hello/text()'

Too bad that the "--xpath" option is only available on RedHat 7, which was not around when this question was posted. – chutz Jan 3 '15 at 14:50
