XML to CSV with XSLT - Grouping nodes

Question

So I\'ve got an XML file I\'ve generated from a php curl response that is then transformed to CSV such that each mods element below is one line. I\'ve got some CSV using the sty

Answer 1

One way to do this is firstly change your XSLT to only select the elements which do not have a preceding-sibling with the same child name (i.e select elements that are the 'first' in each group)

Then, you can define a variable to get the following sibling if (and only if) it has the same name, so you can then check if the current element is indeed in a group of more than 1.

**

(I am not sure if you actually wanted the ** in the final results, or whether they are just there to highlight the group! I am keeping them in my example, but obviously it will be easy enough to remove the relevant lines of code).

To group together the following-siblings with the same name, you could call a recursive template for the first following-sibling

Then, within this template you would recursively call it where the immediate following sibling has the same name

   ;
   
   

Try the following XSLT

   
   

   
      
         
         ,    
         **
         
         
         **
      
      

   

   
      ;
      
      
   

Now, if you could use XSLT 2.0, things become much, much easier, as you could use the xsl:for-each-group construct which, among other things, comes with an operation to 'group-adjacent'. And you could also do away with the recursive template by using the improved xsl:value-of which would have a 'separator' property to use when multiple elements are select.

For XSLT 2.0, the following should also work

    
    

    
        
            ,    
            **
            
            **
