How to parse and modify an xml tag

Question

I have an xml message in which i need to parse and find a particular tag. On that tag data I need to check if all the mandatory data elements are present or not. If a data element is missing i need to add the missing data to the tag. Once enriched i need to resubmit for further processing. Can some one give a few guidelines as to how this can be done using linux scripting. Could the awk command be used to find the tag in the xml message.

awk is more so used for processing textual table data. Using something like Perl might make your life easier - it has many libraries to deal with XML. — Ryan, Feb 16 '12 at 22:05

Processing XML using text processing tools like awk will not scale. Multiple lline data, encoded data etc will make it difficult to handle even small data. Use XML processing library - perl has many. All other languages too.

I'd recommend XSLT. See also the Wikipedia article about XSLT, there are some samples. I think XSLT is great for the job you describe.
