The value of the variable may be an object of any type that can be returned by an expression. If the element has a select attribute, the value of the attribute must be an expression and the value of the variable is the object that results from evaluating the expression. In this case, the content of the element must be empty. If the element does not have a select attribute and has non-empty content such as one or more child nodes, the content specifies the value.
The content is a template that is instantiated to give the value of the variable. The value is a result tree fragment equivalent to a node-set containing just a single root node having as children the sequence of nodes produced by instantiating the template. An error occurs if a member of the sequence of nodes created by instantiating the template is an attribute node or a namespace node, because a root node cannot have an attribute node or a namespace node as a child.
If the content is empty and does not have a select attribute, the value of the variable is an empty string. This will output the value of the first item element, because the variable "n" will be bound to a result tree fragment, not a number. Instead, do either this:. Skip to main content.

Allow 2. Reject 3. For Allow error code will be always 0 and all other case it should be the error code we are getting from incoming request. That is why i was trying to write the logic within for loop which is not quite working. Here is an example implementing your 3 rules for populating the NS1:Access element. As I mentioned in a comment to your question, these rules are not collectively exhaustive - so you will need to add to them in order to cover all possible scenarios:.

Not to mention that xsl:for-each is not a loop. Not sure how we can do without loop. Active Oldest Votes. Is there a reason why you cannot do simply: XSLT 1. Added in response to your added requirement: Here is an example implementing your 3 rules for populating the NS1:Access element. JoelBodenmann I believe it has already been explained a number of times.
In a nutshell, the presumption is that namespaces are there for a reason. If you ignore the namespace, you run the danger of a false positive match with another node having the same local name in a different namespace.
Plus it's ugly. But i have that incoming XML is dynamic one meaning the "Access" tag value can be either 1. As per the given Input. Please let me know the issue.I recently answered a question on a popular programmers forum about how to store and access an array of user-defined variables in a stylesheet and then loop though those variables.
I realized that many developers are not familar with the available techniques for doing this and decided to add an entry in my blog about this topic. User-defined variable arrays within stylesheets are not part of the XSLT specification. The usual way to handle this problem in XSLT 1. These user-defined top-level elements are typically used to store error messages, lookup data, etc.
You can then access these user-defined elements from within your stylesheet by treating the stylesheet as an additional source document and loading it using the document function with an empty string as the first argument. An empty string is interpreted to mean the current stylesheet. If you are using XSLT 2. Another way to store and access this data in a XSLT 2. You may be wondering about this image. It is from the screen of my laptop.
However, XSLT has taken its own remarkable trajectory, as people began to realize that the problem of transforming XML transcended just publishing books and covered transforms from any format to any other. A problem that XSLT adoption has faced comes due to the difficulties in getting older implementations upgraded.
Java ships with Xalan. Xalan has not been improved since it was first incorporated into Java back in and it still uses the very first version of XSLT, standardized in The Linux based libxslt processor is similar; while it is a good implementation for the Linux platform, it has not been upgraded since it was written in the early s.
Why You Should Be Using XSLT 3.0
These versions are backwards compatible, which means that XSLT 1. Moreover, swapping out XSLT versions is typically as simple as dropping a more contemporary engine, such as the Saxon processor, into a folder in your Java project and changing a line in a configuration file. Most Java developers could do it in under ten minutes, and there are both open source and commercial versions of these for free up to a fairly modest licensing fee.Tutorial 3 - XSL ForEach
There really are very few reasons why you should not upgrade. The question, of course, is what benefits do you get for that upgrade? There are a number of them, but it's worth going through the key ones to understand why upgrading preferably to XSLT 3. In XSLT 3. Now, suppose that you wanted to map this to a different data structure, such as an array of objects.
The templates to do so would look something like this:. This can then be converted back to JSON with the xml-to-json function, resulting in the following output:. For instance, the following generates the full name of an employee from the first and last name, using XSLT 1.
Not only does the latter require fewer keystrokes reducing the verbosity of the language but it is also easier to follow, especially with the concat operators " " replacing the concat function. This also solves a big problem with XSLT 1 when you had a select expression which needed both single and double quotes within attributes. A related capability within XSLT 3.

I do not want to loop it beacuse I need to place it in correct TD row. If you pass a node-set to containsit is converted to a string. This means that only string value of the first node is taken.

Extension objects are maintained by the XsltArgumentList class. A qualified name and namespace URI are associated with the extension object at that time. The data types returned from extension objects are one of the four basic XPath data types of numberstringBooleanand node set.
Any method that is defined with the params keyword, which allows an unspecified number of parameters to be passed, is not currently supported by the XslCompiledTransform class. XSLT style sheets that utilize any method defined with the params keyword will not work correctly. For details, see params. Pass the XsltArgumentList object to the Transform method.
