"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

Takeaways:

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.
