Following XSL converts the xml data into a format where first tag of the element is converted into heading and all elements having the same value for first tag will appear in a table below that heading. The Xml elements must be sorted by first tag.
To understand the transformation, consider the following Xml:
<mydata> <contact> <name>Mark</name> <telephone>34546343</telephone> <description>Work</description> </contact> <contact> <name>Mark</name> <telephone>98884748</telephone> <description>Home</description> </contact>= <contact> <name>Mark</name> <telephone>23456123</telephone> <description>Mobile</description> </contact> <contact> <name>William</name> <telephone>23098764</telephone> <description>Mobile</description> </contact> <contact> <name>William</name> <telephone>45645356</telephone> <description>Work</description> </contact> </mydata>
The XSL generates the following output:
Contact: Mark
Telephone Description 34546343 Work 98884748 Home 23456123 Mobile Contact: William
Telephone Description 23098764 Mobile 45645356 Work
