XSLT Interview Question:

What is XSLT data model?

Submitted by: Administrator

XSLT shares the same data model of XPATH with some additions. XSLT accepts a XSLT stylesheet as an input and output is another XML, text or another document. The model is based on text nodes. These text nodes are embedded within element nodes. The model is a hierarchical structure like a tree. The tree has a variety of nodes like- text nodes, attribute nodes, element nodes, comment nodes, and processing instruction nodes. For every node type there is a way of determining a string-value for a node of that type.
