help wanted for comparing two xml files

[dipti1]

Hi,

I need to compare two xml files. I need to compare only the tags and not the values. If it was only to compare two files, I could use File::compare.

However, for my purpose of comparing only the tags, I somehow will have to extract the words between the < and > and compare each of them with their counterparts ( in the other xml file).

The problem is that the strings in the xml files do not necessarily have spaces in between tags or words. I am having difficulty solving this problem of comparing two xml files. Part of xml file looks like:

<name>Priya</name>
<address> California </address>

I should not compare the values like Priya or California. I just have to compare the structure of the two xml files.

If any one could help me or give some idea, that would be great.

Thanks a lot in advance,
Priyanka

If you treating these as more than just files, but as xml files, then you should use modules that treat them as xml files.

http://search.cpan.org/search?query=XML::Simple

The above is the simplest module that you could use, but you'll have to create the data comparison routines yourself.

If you were testing for isomorphism, then you could use some of other cpan module for the data comparison as well:

http://search.cpan.org/search?query=Data::Compare

However, given that you've applied special requirements, you'll most likely have to do the comparison yourself.

There's also an XML:iff on CPAN, although I've not tried it...
