Assigning a string to a variable depending on condition in xslt
XSLT talks of "binding" a variable to a value. The difference between "bind" and "assign" is that a variable is bound to a value as soon as it is declared and remains bound to the same value for as long as it is in scope. Of course, the value that you bind it to can be determined by a conditional expression evaluated at run time. -

Initially, you check for leftA and if it's null then assign leftB as it value for left variable. But the very next statement assigns leftA value without any condition.
Conditional assignment in XSLT?
I've written some XSLT where I want to assign values to some variables. Depending on whether or not a condition is met, I want the variable to be populated with a computed value and I want it to have a default value otherwise.
Setting and Using Variables and Parameters
Parameters. The xsl:param instruction is just like xsl:variable with one important difference: its value is only treated as a default value and can be overridden at runtime. All the stylesheet examples up to this point would work the same way if you substituted xsl:param elements for their xsl:variable elements, but you would have the option of overriding the values when calling their templates.
<xsl:variable>
The <xsl:variable> element declares a global or local variable in a stylesheet and gives it a value. Because XSLT permits no side-effects, once the value of the variable has been established, it remains the same until the variable goes out of scope. Syntax. xml
XSLT: How to Use `if` and `else` Statements
XSLT SWITCH statements are used to conditionally execute a block of code based on the value of a variable. The syntax of an XSLT SWITCH statement is as follows: 3. XSLT Conditional Processing Instructions. XSLT conditional processing instructions allow you to conditionally process parts of an XSL transformation. This can be useful for things like:
XSLT <xsl:variable>
Definition and Usage. The <xsl:variable> element is used to declare a local or global variable. Note: The variable is global if it's declared as a top-level element, and local if it's declared within a template. Note: Once you have set a variable's value, you cannot change or modify that value! Tip: You can add a value to a variable by the content of the <xsl:variable> element OR by the select ...

XSLT/XPath Reference: XSLT elements, EXSLT functions, XPath functions, XPath axes. The <xsl:variable> element declares a global or local variable in a stylesheet and gives it a value. Because XSLT permits no side-effects, once the value of the variable has been established, it remains the same until the variable goes out of scope.
xsl:variable ⚡️ XSLT 3.1 with examples
The value of the variable may be defined either by an expression within the optional select attribute, or by the contents of the xsl:variable element. In the latter case the result is a temporary tree. A temporary tree can be used like a source document, for example it can be accessed using path expressions and processed using template rules.
<xsl:variable> / <xsl:param>
The XPath parser calls the parser's lookupVariable method in an initial attempt to find the variable/parameter instance. If that fails, it goes on to call the symbol table's lookupName() method. If that also fails this means that either: a variable or parameter with the given name does not exist.
Working with Variables
Chapter 8. Working with Variables. XSLT provides the functionality to create special values that can be declared and used by expressions in other elements in the stylesheet. These values are attached, or bound, to named objects called variables. A variable in XSLT can be either global (available throughout the stylesheet) or local (available ...
Predicates & Conditionals in XPath & XSLT
Predicates result in an expression value that is converted to a boolean. If the value is a number, then the position is checked against that number.
Chapter 8. Working with Variables
8.1 Declaring and Binding Variables. Variables are declared in an XSLT stylesheet with either the <xsl:variable> element or the <xsl:param> element. Binding a value to a variable is the process of assigning the variable to a value. Therefore, when a value is assigned to a variable, it is said to be bound to that variable.

XSLT Variable
Definition of XSLT Variable. XSLT variable is defined as special tags used to declare a local or global variable that we make use of to store any values. The declared variables are referenced within an Xpath expression. Once it is set we cannot overwrite or update the variables. The scope of the element is done by the element that contains it.

Re: Conditional variable assignment
If the developer tries to reference the value of n outside of this <xsl:choose>, it will be undefined because of the scoping rules for XSLT variables. Rather than thinking of conditionally assigning a variable, in XSLT you need to think instead of assigning a variable a conditional value. An example will make things clear.
