You use an Assign Variable action to assign a local, page, flow, or application variable a value. This action can also be used to create a local variable.
For example, if your action chain sends a request to a GET endpoint, you can use the Assign Variable action to map the response to a page variable that's bound to a page component. Or, suppose you want to capture the ID of an item selected in a list. You could use a Selection event to start an action chain that assigns the selected item’s ID to a variable.
To use an Assign Variable action to create a local variable:
To use an Assign Variable action for a value assignment:
If you're using an SDP to provide a table or list's data, and you'd like to filter out rows, you can use the Assign Variable action to create and assign the filter criteria to the SDP's filterCriterion property. For further details about using an SDP to filter a table or list's rows, see Filter Data by Filter Criteria .
To use the Assign Variable action's Filter Builder to create the filter criterion for an SDP:
You can use the Filter Builder's Code tab to view and edit the filter's code. After defining a condition on the Builder tab, you will see that the Code tab contains an attribute , op and value property.
Here's an example of a filter with two conditions combined by an AND operator:

You use the xsl:variable statement to create a variable. Either of the following will work <xsl:variable name="cdtitle"><xsl:value-of select="title"/></xsl:variable> <xsl:variable name="cdtitle" select="title"/> They statement in this case would have to be within the loop.
Tip: You can add a value to a variable by the content of the <xsl:variable> element OR by the select attribute! Syntax <xsl:variable name="name" select="expression"> <!-- Content:template --> </xsl:variable> Attributes Example 1 If the select attribute is present, the <xsl:variable> element cannot contain any content.
<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 <xsl:variable name=NAME select=EXPRESSION > TEMPLATE </xsl:variable>
The xsl:variable instruction creates a variable. Its name attribute identifies the variable's name, and the value can be specified either as the xsl:variable element's contents (like the "10pt" in the example) or as the value of an optional select attribute in the xsl:variable element's start-tag.

<xsl:for-each select="/foo/bar"> <xsl:variable name="some-bar" select="."/> <xsl:value-of select="$some-bar"/> </xsl:for-each> Parameters are assigned a value either from the process that invoked the stylesheet (top-level parameter), or from a <xsl:with-param> or from a default value (in which case it behaves as if it was a variable).
To get the value or to output the above statement we can do it as follows: <xsl:value-of select="$animal"/> Mostly we often prefer to use <xsl: variable> in top-level to avoid recalculation while implementation.
xsl:variable Used to declare a variable and give it a value. If it appears at the top level (immediately within xsl:stylesheet) it declares a global variable, otherwise it declares a local variable that is visible only within the stylesheet element containing the xsl:variable declaration.
The xsl:variable instruction creates a variable. Its name attribute identifies the variable's name, and the value can be specified either as the xsl:variable element's contents (like the "10pt" in the example) either as that value of an optional select attribute in who xsl:variable element's start-tag.

Is for aforementioned tracking will work <xsl:variable name="cdtitle"><xsl:value-of select="title"/></xsl:variable> <xsl:variable name="cdtitle" select="title"/> They statement in this case would will to be in the cling.
4 IMHO your code is fine. The "problem" with XSLT variables is that they are NOT variables but more resemble constants: once set they cannot be changed anymore. Also, their scope is restricted to anything that follows their definition until the closing tag. In particular they are NOT visible in any ancestor tag.
Here are some examples of expressions that can be used in the select attribute: Expression. Value. TITLE. The character content of the first child TITLE element if there is one. @NAME. The value of the NAME attribute of the current element if there is one. .
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. Declaring a variable and binding a value to a variable happen simultaneously. It is not possible to declare a variable without also assigning a value to it.
The value can be assigned by either the content of the xsl:variable element or by the select attribute, but not by both. Each variable declaration requires a separate xsl:variable element. Global variables are declared in the top level of the style sheet (as children of the xsl:stylesheet or xsl:transform elements).
Answers. XSLT is not an imperative programming language where you can change the value of a variable. If you want to pass a value from one template to another then you can use a parameter e.g. The fact that you need to modify an <xsl:variable> shows that you are not thinking 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. -

2 Answers Sorted by: 15 Variables are immutable in XSLT, and cannot be changed once set. The variable declarations in the xsl:choose are simply new declarations that at local in scope to the current block. (They are said to "shadow" the initial variable). What you need to do is this...
