Re: [xsl] Two possible group-ending-with nodes

Martin, I see your solution in the previous post and it is cleaner using the
note variable. Thank you very much!

This definitely makes sense. I think it is a group-adjacent problem. Here is
my modified input with the correct output:

 

<?xml version="1.0" encoding="UTF-8"?>

<root>

    <p class="CBBodyIndented">Out 1</p>

    <p class="CBNote">In header</p>

    <p class="CBNoteBody">In content 1</p>

    <p class="CBBodyIndented" style="margin-left:96px;">In content 2</p>

    <p class="CBBodyIndented">Out 2</p>

    <p class="CBBody">Out 3</p>

    <p class="CBBodyIndented" style="margin-left:96px;">Out 4</p>

</root>

 

<?xml version="1.0" encoding="UTF-8"?>

<root>

   <p class="CBBodyIndented">Out 1</p>

   <div class="note">

      <div class="note-header">

         <p class="CBNote">In header</p>

      </div>

      <div class="note-content">

         <p class="CBNoteBody">In content 1</p>

         <p class="CBBodyIndented" style="margin-left:96px;">In content
2</p>

      </div>

   </div>

   <p class="CBBodyIndented">Out 2</p>

   <p class="CBBody">Out 3</p>

   <p class="CBBodyIndented" style="margin-left:96px;">Out 4</p>

</root>

 

Below is my stylesheet. I am using the same for-each-group group-adjacent
loop twice because I need some content inside the <div class-"note-content">
and the rest of it outside. Any suggestions for a better approach will be
appreciated. Thank you!

It ends the first inner group at the first element because it matches the
first condition, p[@class='CBNoteBody']; it ends the second inner group at
the second element because it matches the second condition
p[@class='CBBodyIndented'][@style='margin-left:96px;'], and it ends the
third inner group at the third element because everything after the last
matching element goes in a final group regardless.
