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!

XSL Loop and incrementing variable

Asked by ste_89 in Extensible Stylesheet Language Transformation (XSLT), Extensible Markup Language (XML), Oracle 3rd Party Tools

Tags: , , ,

We are using Oracle XML Publisher to generate PDF formatted Purchase Order Reports. We have tried Oracle Support, but haven't got anywhere, hence trying here...

As part of this work, we have hit a problem.

Part of the XML contains the following data:


<PO_DATA>
    <LINE_ATTACHMENTS>
        <TEXT> Telephone Number=6955_1 </TEXT>
        <ID>765923</ID>
        <TEXT> Telephone Number=6955_2 </TEXT>
        <ID>765924</ID>
        <TEXT>Telephone Number=6955_3</TEXT>
        <ID>765925</ID>
    </LINE_ATTACHMENTS>
</PO_DATA>


What we want to do is to loop through the values in the <LINE_ATTACHMENTS> tag, and output the Text Value.

If we try the following snippet:


<?/PO_DATA/LINE_ATTACHMENTS/TEXT[3]?>


Then when we view the output, the XSL will always display the value of the 3rd iteration of the <TEXT> tag.

That's okay - but we don't want to hard code the [3] value. We want instead for the number there to be the row count that is currently being used.

We have tried this:


<?/PO_DATA/LINE_ATTACHMENTS/TEXT["row:position()]?>


But a long error message was returned.

Basically, we want to increment a variable for each loop through the data, and output the value of that incremented variable in the square brackets as detailed above.

Can this be done?

Thanks
