Tool for processing a text file with regular expressions and substitution replacement?

Question

*nix-like systems

I often meet a task at work: there is an xml file in which

<position x="100" y="100" />

and I need to work out all such or similar matches, for example, increase the x coordinate by 2.5 times. I want to find a universal solution for a whole class of such problems. Process some of the lines in the file according to a certain rule and generate a new file.

Answer 7

Word processors (perl, php, etc.). Yes, of course, programming text processing scripts is not exactly a “tool”, but it is unlikely that something can make such tasks easier and more automated. In addition to regular expressions, xml can be processed by a full-fledged xpath-aware handler (such as DOMDocument).
