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!

Parsing Simple XML with Javascript

Asked by niko86 in JavaScript, Extensible Markup Language (XML), Asynchronous Javascript and XML (AJAX)

Tags: , ,

I recently began to learn Ajax, now im stuck with a little Application.
It sends a Post Request containing a path to a PHP Page, this Page returns a simple XML structure containing the Folders in the Directory specified by the path.

A sample of the XML can be found in the Code Section.

What i am trying to do is parsing the xml.
I want it to be displayed row by row, doesnt matter if a table is used for this or if there are just text lines seperated by "<br>"

This is what i got so far:Start Free Trial
