I'm new to dealing with XML, so I thought I'd solicit some recommendations as to which modules are best suited for certain tasks. I have a couple of different tasks for a couple of different scripts, so feel free to suggest a different module for each need if you think that one module doesn't cover all of these nicely. What in your opinion is the best module (XML::Parser? XML::Twig? XML::XPath? XML::LibXML? XML::Simple? Other?) to use for each of these tasks? If you care to submit a code snippet along with your suggestion to demonstrate, I'd be most grateful as it'll probably help cut down my learning curve. =)

  1. Parse an XML file and retrieve all the comments.
  2. Parse an XML file and get a list of all values enclosed in a particular tag.
  3. Parse and XML file and get a list of all tags it contains.
  4. Parse an XML file, find and change a particular value inside a particular tag, the write the XML file back to disk. E.g. change "<greeting>Hi</greeting><greeting>Hello</greeting>" to "<greeting>Hi</greeting><greeting>Goodbye</greeting>".
  5. Retrieve content from an XML file based on a given XPath.

Thanks!
