saxon:assign element in stylesheet.
The saxon:assign element has mandatory attribute name and optional attribute expr.
It also allows xsl:extension-element-prefixes etc.

Method Details
-
isInstruction
public boolean isInstruction()Determine whether this node is an instruction.- Overrides:
isInstruction
in classStyleElement
- Returns:
- true - it is an instruction
-
isAssignable
public boolean isAssignable()Description copied from class:XSLGeneralVariable
Test whether it is permitted to assign to the variable using the saxon:assign extension element. This will only be true if the extra attribute saxon:assignable="yes" is present.- Overrides:
isAssignable
in classXSLGeneralVariable
-
allowsAsAttribute
protected boolean allowsAsAttribute()- Overrides:
allowsAsAttribute
in classXSLGeneralVariable
-
validate
Description copied from class:StyleElement
Check that the stylesheet element is valid. This is called once for each element, after the entire tree has been built. As well as validation, it can perform first-time initialisation. The default implementation does nothing; it is normally overriden in subclasses.- Overrides:
validate
in classXSLGeneralVariable
- Throws:
XPathException
-
compile
Description copied from class:StyleElement
Compile the instruction on the stylesheet tree into an executable instruction for use at run-time.- Specified by:
compile
in classStyleElement
- Returns:
- either a ComputedExpression, or null. The value null is returned when compiling an instruction that returns a no-op, or when compiling a top-level object such as an xsl:template that compiles into something other than an instruction.
- Throws:
XPathException
