– Introduction – Principle
- Plain text is called text
element. It is element that differs from all other since it doesn't have tag.
- test.xml has following
elements: <people>, List of students, <student>, <name>,
Jack, <age>, 23
- <people> element is
called root element since it is the first one.
- Since <student> element
is placed inside <people> element it is said that:
- <student> is child of
- <people> is parent
- Value of text element is
it's string with.
- Value of all other
element's is string with values of all of it's text subelements.
- XSLT goes through nodes of
test.xml begining from the root element <people>.
- When XSLT gets to a node
which matches some of the defined templates it executes that template.
- If no such template can be
found SLT executes default template which is defined as follows:
you apply template to an element, process its child elements
- when you apply template to a text node, return its value
- This info was taken from http://www.dpawson.co.uk/xsl/sect2/defaultrule.html
- Since no template is defined
for <people> default one is used which starts taking children.
- First child is text element.
There is also no template defined for it so default one is taken which simply
returns the text.
- For the next element,
<student>, we have defined template which simply returns string
- Children on <student>
are skiped since we haven't defined any operations on them in our template.
