xsl:for-each-group

The xsl:for-each-group element selects a sequence of nodes and/or atomic values and organizes them into subsets called groups. There are four possible ways of defining the grouping:

Saxon implements the xsl:for-each-group instruction in full. For examples of using the instruction, see the XSLT 2.0 specification.

In XSLT 3.0, the capabilities of the xsl:for-each-group instruction are extended by virtue of the fact that the pattern used in group-starting-with or group-ending-with can now match atomic values as well as nodes.
