xml - Format and combine output of xpath in bash -

i'm trying parse xml input using bash utility xpath:

<?xml version="1.0" encoding="utf-8"?> <feed version="0.3" xmlns="http://purl.org/atom/ns#">     <entry>         <title>title 1</title>         <author>author 1</author>     </entry>     <entry>         <title>title 2</title>         <author>author 2</author>     </entry> </feed> 

i need output in format:

1. title: title 1    author: author 1 2. title: title 2    author: author 2 

i've fiddled around lot trying achieve in simple way (using single xpath command, or @ 3-4 commands), efforts have been in vain. please me out this?

bash version

#!/bin/bash count=1 input=input.xml  while [ -n "$title" -o $count = 1 ]     title=`cat $input | xpath //entry[$count]/title 2>/dev/null | sed s/\<title\>//g| sed s/\<\\\\/title\>//g`     author=`cat $input | xpath //entry[$count]/author 2>/dev/null | sed s/\<author\>//g| sed s/\<\\\\/author\>//g`     if [ "$title" -a "$author" ];         echo $count $title $author     fi     count=$((count+1)) done 

perl version (untested) ...

#!/usr/bin/perl use xml::xpath;  $file = 'input.xml'; $xp = xml::xpath->new(filename => $file); $count = 1; foreach $entry ($xp->find('//entry')->get_nodelist){     print $count;     print 'title:' . $entry->find('title')->string_value;     print 'author: ' . $entry->find('author');     $count++; }
