Suggested October 2023 How Does The Xslt Position Work With Examples?

Definition of XSLT position

XSLT position is a useful piece of function that returns the exact position from the current context node within the node list. Position() function is a recommended operation to return the node position that is being processed.

Syntax:

The Syntax of the XSLT position is given as

If the position=1, the first element in the XML file returns a position of 1. Similarly, it varies for the number.

How does the XSLT position work?

The Position() function works by applying few conditions to the Xpath by choosing a specific node.

Position() = n, N is the number to find the position of the node within the nodeset.

Using modulo function to determine the position. We need to use products bounding so that the result will be in a n product of a row. So modulo could be used like:

To do the generic position on the functionality daily news class Position() is used in the selected node-set so that a fresh position counter is revealed. For instance, to set the position <6 and mod2=1 for the daily news, hope this works.

Next to find the last node in a set we can use position along with the keyword last ().

With the apply template and with few attributes as input the input may process like

This process each element internally with the position attribute in the apply-template format.

Examples

This section gives a code implementation to illustrate the Position() function with a different example. Let’s get started,

Example #1

XML

XSL

Explanation

When the above XSLT file applied to XML it maps the element ‘coin’ whose content holds the position in the order from 1 to 4 as there are 4 coin elements. And the Output is shown in the HTML format.

Output:

Example #2

XML

XSL

Explanation

Output:

Example #3

XML

XSL

Explanation

The index number of the node is retrieved in the above stylesheet which returns the odd number as an index.

Output:

Example #4

XML

XSL

Explanation

Having an XML file above with the game elements we need to display the position of an element in a sort function in ascending order. Therefore the output is numbered with 5,4 and so on by retrieving the text content along with the function.

Output:

Example #5

XML

XSL

Explanation

The above example returns a value with an XSL:for-each as they provide access to novelist element by the position() to return a value greater than 2. The XSLT template uses the Position() function to manipulate the number of Essays being processed, concerning other nodes in the list.

Output:

Example #6

XML

XSLT

Explanation:

In the above code snippet, we have examined the last () function in the position to find the exact location of the list by using the for-each statement. By then the frame numbers are returned in the result as a result of the last value also we have achieved using various conditional statements to return a value.

Output:

Conclusion

Coming to an end, we have seen a way to use the Position() function to retrieve the position number from the code which is given in an easy way to understand and well structured. And also done with lots of examples to show how the function works. Therefore, we have explored the full power of the function to understand the concept and to work in various applications.
