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!

XSLT poduces repetitive nodes on an XML file

Asked by mzm_uk07 in Extensible Stylesheet Language Transformation (XSLT), Extensible Markup Language (XML)

Tags: ,

Hi,

I have an XML file that I transform using XSLT. Basically I'm trying to update users database.

I have a unique id variable that I use to search the DB before adding the new user, only when the id DOES NOT exist the new user should be created..

The problem is I either get all or none!

The new user is added again and again regardless  of the id or not added at all when I tried modifying the code!

Now, I know it must be something very simple that is wrong but I can't see it:(

The problem is in this bit that I'm not sure how to go about it:

 <xsl:for-each select="Users/userProfile">
      <xsl:choose>
        <xsl:when test="id/text()=$id">
 <!-- 2- if yes=>error message=>user exists-->
          <xsl:message terminate="yes">Error: User exists</xsl:message>
        </xsl:when>
      </xsl:choose>
    </xsl:for-each>

 <!--3-If not => create new elements: user profile, username, id, level-->

<xsl:element name="userProfile">
<xsl:element name="id"><xsl:value-of select="$id"/></xsl:element>
<xsl:element name="username"><xsl:value-of select="$username"/> </xsl:element>
<xsl:element name="level"><xsl:value-of select="$level"/></xsl:element>
</xsl:element>

See the code below please..

Thanks a lot!
