kyle has asked for the wisdom of the Perl Monks concerning the following question:
The question came to me one afternoon, "how long would it take you to write a Perl script that would remove a specific character from within XML tags?"
I replied,
A quick and dirty (i.e., error prone) would take minutes.
To use a real XML parser and guarantee that I don’t corrupt the file in the process might take a couple hours because I’m actually not that familiar with XML.
I wouldn’t be surprised if you could ask the question politely at perlmonks.org and get it written for free in about a half hour.
This was a need-it-now situation, so we went with the quick and dirty:
use strict; use warnings; while (<>) { s{(<[^?<>]*\.[^<>]*>)}{ (my $tagname = $1 ) =~ tr/.//d; $tagname; }eg; print; }
The input to deal with looks like this:
<?xml version="1.0"?> <TOP> <SUB> <THIS>STUFF</THIS> <SOME.TYPE>T</SOME.TYPE> <SOME.OTHER.TYPE>BLAH</SOME.OTHER.TYPE> </SUB> </TOP>
The problem is the dots in the tag names. They need to be stripped out. The output should look like this:
<?xml version="1.0"?> <TOP> <SUB> <THIS>STUFF</THIS> <SOMETYPE>T</SOMETYPE> <SOMEOTHERTYPE>BLAH</SOMEOTHERTYPE> </SUB> </TOP>
Note that my first implementation actually took the dot out of "<?xml version="1.0"?>". Luckily I had the good sense to look at a 'diff' before I stopped debugging.
So, monks, I seek your wisdom. What is the right way to do this so that I don't someday accidentally annihilate some important input? Any guidance you can offer would be appreciated.
