pc:assign-string

note

This article is about the pc:assign-string Blend directive.

pc:assign-string

Evaluates an expression, converts the resulting value to a string using XSLT 1.0 conversion rules, and stores the resulting string in (= assigns the resulting string to) a named variable. The variable is global: from any later script section you can refer to its value by writing $variable.

If a variable by the same name is already instantiated, its value is silently overwritten. This is the difference with pc:assign-string-default.

You have the option to assign multiple strings in a single pc:assign-string directive.

Syntax

<pc:assign-string
  [  *variable* = "*expr*" ... ] />

For each variable, variable identifies the variable by name and expr is the value you provide for the variable. Expr may be submitted either as a literal or as an XPath expression presented as an attribute value template, ie., surrounded by curly braces (  ).

Example

<pc:assign-string
     username="ADMIN"
     workingdir="{directories:Get()}"
     servername="{path:GetFileName(directories:Get())}" />
