XML Parse Change a Value and Write Back

anshumangoyal has asked for the wisdom of the Perl Monks concerning the following question:

I have an XML File. I want to change some values of some parameters which I want to change while parsing the file using XML::Simple Module. Problem is parsing and changing the parameter values is OK, but when I want to write back the file, the whole content changes. I tried all options mentioned in CPAN module for this but none of this is working. I simply want to parse the XML file, change the parameters and write it back in another file. I also dont want to loose any comments etc. Is there any easy way to do that?

The whole Output XML goes into a mess. I just want the output to look how my input is. Isn't there any other choice?	[reply]

Don't use XML::Simple. There's ,no easy solution, I think, because there's probably no XML module around that guarantees that the produced attributes are in the same order as they are parsed. But XML::Simple guarantees almost absolutely nothing, not even that the output will have a similar structure as the input. It may even move data from content to attribute or vice versa. the only guarantee you get on the output of XML::Simple is that XML::Simple will be able to read it back in.	[reply]

Why not read the post that I linked to? Two other methods were mentioned: 1) XML::Twig 2) search and replace using a regular expression.	[reply]

I just want the output to look how my input is. What goes wrong with your subsequent processing if the syntactic layout of your XML changes even though the semantic layout is retained? With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
