XSLT 1.0: Fundamental concepts

Designed to transform document structure

Node renaming, moving, re-ordering, etc

Limitation: transforming document content is cumbersome

Based on two processing models

Source driven (push) : template pattern
Target driven (pull) : node selection

Borrow some functional language aspects

Variables are immutable
Template can be seen as function
No high-order function

Few types: Numeric, boolean, string, node and nodeset
