I need to nest xsl:for-each elements (or do something similar) to compare values to see if the inner element should be printed or not. It would look something like this:   <   <    <  <   <  <   <  <   < Now, in the I need to compare a value in the /loan/person element that I'm currently in to a value in every iteration through the /loan/money (for-each) so that an income element is generated where there is a match. Is this possible??? thanks. sjj    More>>

Here is an complete answer for you, include the XMLs XSLT and analysis.



Q. Should I use nested loop in this problem?

A: Interesting one, see the XML source and required result XML.

XML sourece



  
    John Doe
    111111111
  
  
    Mary May
    222222222
  
  
    111111111
    33400
  
  
    111111111
    1000
  
  
    222222222
    25000
  
  
    333333333
    40000

Required XML result

XSLT soureces for comparison 


  
      match="/people/income" 
    use="ssn" />


Important points here:


  • Loops here are nested. The outer loop is on , the inner loop is on the key

  • If inner loop is on , then it would be very inefficient.

  • The and key() function are playing the same role as index in database.

Yes it is possible. How you do this depends on the structure of your document.


What are the values you are comparing? What is the structure of your document?
