In case the p prefix is already mapped in your XML, then you'll need to modify the script to use another prefix. A one-off script which serves the narrow purpose of extracting module names from an apache maven file.

If the parsing is not done like this, the last tag in the XML file is never reached. This can be problematic if you intend to output another XML file at the end of the while loop. If this is side job, it is waistfull to look for the proper tool, then learn it Awk can do it in minutes.

My programs have to work on all above mentioned and more kinds of data. Hell, I do not want to test 30 tools to parse different formats I need if I can awk the problem in minutes. I need a single solution for all of them. As an example: my SmartHome program runs our homes. While doing it, it reads plethora of data in too many different formats I can not control. I never use dedicated, proper tools since I do not want to spend more than minutes on reading the data I need.

It took 4 lines of awk to solve the problem perfectly. So, adapt idea to each need before using it! Second part simply looks it there is wanted string in a line RS and if so, prints out needed fields FS. The above took me about 30 seconds to copy and adapt from the last command I used this way 4 times longer. And that is it! Done in 90 chars.

But, I always need to get the data neatly into variables in my script. I first test the constructs like so:. In some cases I use printf instead of print. When I see everything looks well, I simply finish assigning values to variables. I know many think "eval" is "evil", no need to comment : Trick works perfectly on all four of my networks for years.
