Have you tried it?

NAME
XML::Quote - XML quote/dequote functions SYNOPSIS
use strict; use XML::Quote qw(:all); my $str=q{666 > 444 & "apple" < 'earth'}; print xml_quote($str)," "; # 666 &gt; 444 &amp; &quot;apple&quot; &lt; &apos;earth&apos; my $str2=q{666 &gt; 444 &amp; &quot;apple&quot; &lt; &apos;earth&apos;}; print xml_dequote($str2)," "; # 666 > 444 & "apple" < 'earth' my $str3=q{666 > 444 & "apple" < 'earth'}; print xml_quote_min($str3)," "; # 666 > 444 &amp; &quot;apple&quot; &lt; 'earth' DESCRIPTION
This module provides functions to quote/dequote strings in "xml"-way. All functions are written in XS and are very fast; they correctly process utf8, tied, overloaded variables and all the rest of perl "magic". FUNCTIONS
$quoted = xml_quote($str); This function replaces all occurences of symbols '&', '"', ''', '>', '<' to '&amp;', '&quot;', '&apos;', '&gt;', '&lt;' respectively. Returns quoted string or undef if $str is undef. $dequoted = xml_dequote($str); This function replaces all occurences of '&amp;', '&quot;', '&apos;', '&gt;', '&lt;' to '&', '"', ''', '>', '<' respectively. All other entities (for example &nbsp;) will not be touched. Returns dequoted string or undef if $str is undef. $quoted = xml_quote_min($str); This function replaces all occurences of symbols '&', '"', '<' to '&amp;', '&quot;', '&lt;' respectively. Symbols ''' and '>' are not replaced. Returns quoted string or undef if $str is undef. EXPORT
xml_quote(), xml_dequote() are exported as default. PERFORMANCE
You can use t/benchmark.pl to test the perfomance. Here is the result on my P4 box. Benchmark: timing 1000000 iterations of perl quote, xs quote... perl quote: 108 wallclock secs (88.08 usr + 0.01 sys = 88.09 CPU) @ 11351.64/s (n=1000000) xs quote: 20 wallclock secs (16.78 usr + 0.00 sys = 16.78 CPU) @ 59591.20/s (n=1000000) Benchmark: timing 1000000 iterations of perl dequote, xs dequote... perl dequote: 106 wallclock secs (85.22 usr + 0.09 sys = 85.31 CPU) @ 11721.54/s (n=1000000) xs dequote: 19 wallclock secs (15.92 usr + 0.02 sys = 15.94 CPU) @ 62743.13/s (n=1000000) AUTHOR
