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.

Get image path from RSS feed and save to sql database.

Asked by Qsorb in ColdFusion Application Server, Cold Fusion Markup Language

RSS feeds such as Yahoo.com that contain images, I'd like to save the img src image path from the feed to a database.

I'm already saving the feeditems TITLE, DATE and CONTENT into separate columns and I can identify if there's an image in the CONTENT but understanding how to get the url path is beyond me.

Each feed has about 20 different stories and 20 different images.

There are many more feeds other than Yahoo so we can't just use it as a model. The solution should include a method to get the full src parameters and the image path for any RSS story that contains an image.

An example yahoo image path is:

http://d.yimg.com/a/p/ap/20090830/capt.c6dc2bf1604347cc94d5258779fd5c65.china_myanmar_xhg106.jpg

The image information and path is contained in feeditems.content. But how do I get that path out and save it?
