Grouping elements on the same level

[dirtyv]

I'm having an issue with my transform and was hoping for some ideas, I'm dealing with a really flat input document where all important nodes are siblings of one another. It kind of looks like this:\[code\]<title1> Rule 51 </title1><p> text here </p><p> text here </p><note> Source </note><p> text here </p><title1> Rule 52 </title1><p> text here </p><p> text here </p><note> Source </note><p> text here </p>\[/code\]My goal is for this input to look like this:\[code\] <section> <title1> Rule 51 </title1> <p> text here </p> <p> text here </p> <note> Source </note> <p> text here </p> </section> <section> <title1> Rule 52 </title1> <p> text here </p> <p> text here </p> <p> text here </p> <p> text here </p> <note> Source </note> <p> text here </p> </section>\[/code\]As you can see above my main goal is grouping each title1 and all of it's following siblings until it hits another title1 into a section element. Any ideas??Thanks in advance.
