`<xsl:template match="xhtml:style">
<xsl:variable name="text" select="text()"/>
</xsl:template>`
This is my template having local variable whose value would be the internal styles of html and i want these internal style data to be a global variable value so that i could access this value in other templates for further processing.
I want to use internal styles data for further processing so i think of using this approach.
How could i insert value to global variable from local variable of a template.???

This is a FAQ -- you can't.
XSLT is a functional programming language and among other things this means that a the value of a variable, once defined, cannot be modified.
You can achieved what you want in a much simpler way -- define the wanted global variable simply as (a child of `xsl:stylesheet'):
<xsl:variable name="vYourGlobalVar" select="(//xhtml:style)[1]/text()"/>

I have environmental variable called ENV, which holds the DEV,QA OR PROD region as value. When the server.xml loaded it includes the corresponding db configuration using this variable. For ex: db-config-${env.GAH_ENV}.xml
I would like to pass the same value to the batch job xml as a job parameter or properties to any of the class. How Can I do that.
below code snippet not working
<property name="environment" value="${env.GAH_ENV}"/>
The short answer is that using a batch property may not be a good solution and you might consider something else like MicroProfile's #ConfigProperty.
The reason is there's not a built-in way to access environmental variables through JSL substitution. There is also not a convenient way for one artifact to set a property value to be used by a second artifact running later within the job execution.
In the special case that you are starting the job from within the same JVM it will execute, of course, you could pass the env var value as a job parameter.
But in the general case, if you can change the Java code and you don't really need a batch property I would use a MicroProfile Config property instead, injected via #Inject #ConfigProperty.
By doing so you lose the batch-specific substitution precedence, including the override available via job parameters passed with the submit/start. You also give up the ability to use this property in other JSL substitutions (to "compose" its value into other batch properties via other substitutions).
But you at least get a property with its own various levels of precedence/override (e.g. server config, env var, microprofile-config.properties), which is more flexible than just always reading the env var via System.getenv( ).
This is certainly an area to consider for the next version of the (now-Jakarta) Batch spec.
A program variable is an abstraction of a computer memory cell or collection
of cells. Programmers often think of variable names as names for memory locations, but there is much more to a variable than just a name.
In this case, what is an anonymous variable?
What does the below statement mean?
Variables without names are called anonymous variables.
Can you provide language specific examples for the same?
In C++, reference variable to const can be initialized by constant.
In this point, temporary variable is created in memory to grab the constant.
const int &ref = 3;
like this. so we can call this temporary variable to "anonymous variable".
Variables are where you store you values. 'Variable Name' is the usually the easiest (and more human-like) way to locate your value.For example, if I am a variable, you can get my value by calling my name, and the combination of my value and my name is called 'variable'.
However, not all variables need a name.Sometimes you just use them once and don't need them anymore; and in that case, a name is unnecessary.
The example given by #BAE HA RAM is a telling one,in which case you don't need a name for the value but ref to it by a pointer(But still got a name for that pointer)..
There are also many other anonymous things, anonymous type, anonymous function and so on. Most of them are created to avoid too many meaningless names for the things that you only need to run once.
I'd like to know which language you are using, so more specific example can be given...
I am writing a procedure in scheme and I am trying to manipulate the values of variables. I use the define function to give a value to a variable but I can't change the value. I would have used the let function but the variable change is only effective in the body of the let function. Are there other ways to manipulate variabes and be able to view the changes from anywhere in the procedure?
Thanks
you can use set! set-car! set-cdr! after the variable has been defined
Could xsl:variable be defined twice with same name in same scope.
For code similar to the following:
<xsl:template match="\">
<table>
<tr><td>
<xsl:variable name="status" select="normal"/>
</td></tr>
<tr><td>
<xsl:variable name="status" select="failed"/>
</td></tr>
</table>
</xsl:template>
Maybe it depends on browse's type. What is the standard?
First, two variables never have the same scope. Even if they are both global, the scope of the variable excludes its own select expression, so the scope of the two variables is different.
Second, in your example the scope of the two variables isn't even overlapping. Each variable is confined to its own containing td element.
For two global variables, the rule is that you can have two variables with the same name provided they have different import precedence, in which case all references are treated as references to the one with higher precedence.
If one variable is local and the other is global, then the local variable wins if it is in scope.
If you have two local variables with overlapping scope, this is an error in XSLT 1.0, but is permitted in XSLT 2.0; within the overlap area, the variable with smaller scope wins.
It is an error if two or more top-level variables (outside any template) have the same name.
Similarly it is an error if two or more variables within the same template have the same name.
But it is allowable for a variable within a template to shadow a variable of the same name at the top level.
There is no clash between variables unless their scopes (the parts of the stylesheet where the variables are visible) overlap. The scope of a variable inside a template includes its following sibling elements and their descendants. The scope of a top-level variable is everywhere in the stylesheet after that variable.
I have found the key.
MSXML 3.0 supports only XDR schemas, it does not support XSD schemas. MSXML 4.0, MSXML 5.0, and MSXML 6.0 support XSD schemas.
In my xslt file I want to apply templates to the xml but only if an id of that piece of content within the xml matches an id calculated in vb.
Hopefully some code will make this clearer:
<xsl:variable name="ContentparId" select="/Page/descendant::Content/#parId"/>
<xsl:variable name="parIdfromfref" select="mnPageId"/>
<xsl:template match="Page">
<xsl:if test="$ContentparId = $parIdfromfref">
<xsl:apply-templates select="/Page" mode="addModule">
ContentparId is the attribute parId of Content in the xml. I want to compare this with mnPageId which is defined in vb (a foreign reference is passed through and the pageId that matches that foreign reference is returned)
I know the rest of the code does what I want it to do because if I manually change mnPageId for a correct pageId then I get the xml that I want back.
So, is it possible to use a variable that has been declared in vb in xslt? If so, how?
Well an XSLT stylesheet can have global parameters in the form of
<xsl:param name="mnPageId"/>
that can be set from outside the stylesheet before an XSLT transformation is run programmatically. So that is a possible approach, define mnPageId as a global stylesheet parameter that your VB code running the transformation then sets as needed. You can read up the section on MSDN http://msdn.microsoft.com/en-us/library/dfktf882.aspx on how to set parameters with .NET code when running a transformation.
