Grouping help

I have a large well-formed XML table, created from a database made up of thousands of rows. Each row has 18 cell elements. I need to transform those cells into XML for a parts list. I'm going to try and provide abbreviated samples of the input and output. I have what code I need to structure my output, I'm just stuck on properly identifying the grouping.

I need group groups of the rows together based on value in one of the cells (<cell colNum="10">). There could be ten rows with that same value in cell[10) with a value of "1". Then five rows after that where cell[10] has a value of "2". Then there could be ten rows where cell[10] has the value of "3". I need to gather all the 1's together to build a parts list item. Then all the 2's, then the 3's and so on.

I've written this, but my output isn't what I'm wanting or expecting.
