- 1 compares sorted and unsorted xsl:for-each element
- 2 for-each select="addressbook/address" and sort
- 3 for-each select=//address[generate-id(.)=generate-id(key(zipcodes, zip)[1])]
- 4 for-each select=preceding-sibling::address[zip=./zip]
- 5 Nested for-each loop with sorting
- 6 Output xml elements in for-each loop
- 7 The xsl:for-each element allows all nodes in a node-set to be processed according to the XSLT instructions nested inside the xsl:for-each element.
- 8 Use for-each loop to output list items
- 9 xsl:for-each instruction contains a template, which is applied to each node selected with select attribute.
