Hello, there. I have a file that's a horrible, horrible mess. (Basically, it's an export from a firewall config.) The people who generated the file didn't think that putting a newline in the middle of a hostname would ever be a problem. It is.
Here's an example of the stuff in the file:

In file1 field $18 is removed.... column header is "Otherinfo", then each line in file1 is used to search file2 for a match. When a match is found the last four strings in file2 are copied to file1.
Maybe:
cut -f1-17 file1 and then match each line to file2

xml::quote
Quote(3pm) User Contributed Perl Documentation Quote(3pm) 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 > 444 & "apple" < 'earth' my $str2=q{666 > 444 & "apple" < 'earth'}; print xml_dequote($str2)," "; # 666 > 444 & "apple" < 'earth' my $str3=q{666 > 444 & "apple" < 'earth'}; print xml_quote_min($str3)," "; # 666 > 444 & "apple" < '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 '&', '"', ''', '>', '<' respectively. Returns quoted string or undef if $str is undef. $dequoted = xml_dequote($str); This function replaces all occurences of '&', '"', ''', '>', '<' to '&', '"', ''', '>', '<' respectively. All other entities (for example ) 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 '&', '"', '<' 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
