XML Tutorials - Herong's Tutorial Notes

∟XSLT Elements as Programming Statements

This chapter provides tutorial notes and example codes on XSLT programming statements. Topics include introduction of XSLT elements: 'value-of', 'variable', 'for-each', 'if', and 'choose'; example XSLT templates with programming techniques of declaring variables, evaluating expressions, running loops, generating conditional outputs.

"value-of" - Evaluating XPath String Expressions

Examples of Using "value-of" Elements

"{expression}" - Shorthand of "value-of" Elements

"variable" - Declaring Variables

"for-each" - Looping through a Node Set

Examples of Using "for-each" Elements

"if" - The Conditional Element

"choose" - The If...Else Element

Conclusion:

• A "value-of" element can be used to evaluate an XPath expression to produce a string value.
• "{expression}" is a shorthand version of the "value-of" element.
• A "variable" element can be used to declare a variable to store a value to be used later.
• A "for-each" element can be used to repeat a block of contents over a node set returned by an XPath expression.
• An "if" element can be used to put a block of contents under a condition.
• A "choose" element can be used to put different blocks of contents under different conditions.
