What is XSLT and what is it used for?

XSLT stands for Extensible Stylesheet Transformation Language. It is a style transformation markup language written in XML format. It can convert XML data documents into another XML document L or other types of formats (can recognized by the browser). Such as: XHTML document, HTML document, etc.

XSLT is part of the XSL specification. language).

XSLT is used to define transformation rules to be applied on the target XML document.

How XSLT works

During the transformation process, XSLT uses XPath (a navigation language in XML documents that is part of the XSL specification) to find matching template parts (can be multiple) in the target document. Once a match is found, XSLT converts the matching portion of the target document into a result document (a formatted document in XML, HTML, or text format). The resulting document is then used by the XSLT formatter to generate the actual output and display it to the end user.

Advantages of XSLT

1. Separate because it can apply user-defined transformations to XML documents; and the output can be HTML, XML, or any other structured document regardless of platform.

2. Traversing XML documents is more convenient than the traditional method, and the performance of processing XML documents is better. Because XSLT templates are based on XPath schema, XSLT uses XPath to locate elements/attributes in XML documents.

3. XSLT is based on templates. Therefore, it is more conducive to document changes than low-level DOM and SAX.

4. Make the application UI script clean and tidy and easy to maintain.

5. XSLT can be used as a validation language because it uses tree pattern matching method.
