How to put a page break when a value changes

Question

Hi there, I am very new to BI Publisher. I realize this is a really SIMPLE question, but I can't seem to find a CLEAR answer.
I have a set of data that I have a repeating group for in my RTF template and it works great. But I want to have a page break each time one of the values changes and I cannot figure out how.
here is the xml

I want the g_item_no (repeating group) to have a page break each time LOCATION changes.

Answer 1

You can declare two variables, to hold the previous and current LOCATION values and break the page when it differs.
Or just before your end-for-each, have this code.
<?if:position()!=1 and position()!=last() and LOCATION!=following::LOCATION[1]?><xsl:attribute name="break-before">page</xsl:attribute><?end if?>
Ensure that its placed in a form field.
This will have a page break when LOCATION changes.
