The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Commandline xpath query

Asked by mreuring in Mac OS X, Perl Programming Language, Bourne-Again Shell (bash)

Tags: perl, bash, OSX, xpath, applescript

I'm writing an AppleScript action for iTunes that needs to query some information from an XML file, which isn't available natively :(. Currently I'm using 'xmllib' from http://www.satimage.fr/software/en/downloads/downloads_companion_osaxen.html to run xpath queries in applescript. But I wan't to write this script without any 3rd-party dependencies, if at all possible and for this part of the process that I'm automating, XMLLib is the only 3rd party dependency.

So, now I was wondering if I could use any of the built-in (pre-compiled) tools that will run from commandline to query an xml-file using xpath. Considdering an xpath that returns a string, '//Series[1]/id[1]/text()', this would be quite acceptable to me and would negate the need for installing the above-mentioned scripting plugin. For instance I was wondering if Perl or PHP could be abused to do this for me, I've seen similar tricks somewhen/where but I have hardly any experience with PHP and 0 with Perl, nor is Bash-scripting among my strengths :)

Requirements would be for this commandline tool to be available on OSX.4 running on a PowerPC, since my media-server is an old G4 that doesn't run any later version :)

FYI, the AppleScript action, when 'finished', will be opensourced.
