XSLT processor

from Wikipedia, the free encyclopedia

An XSLT processor is a software for converting documents by means of a XSLT - stylesheets . The result is a new document that can be processed further (e.g. as a DOM object ) or output to a file.

The XSLT processor reads the input document and the stylesheet and parses them. Starting with the root element of the document, the XSLT processor then checks which template (rule) of the stylesheet is used. The template found in this way determines what is written to the output. In many cases this is the content of the current node (XSLT term: the context node ) or an algorithmically calculated result based on it. In addition, the template determines which document parts are processed next: for example the children of the context node, other parts of the input document or external documents. In addition to the rules explicitly formulated in the stylesheet, predefined rules (such as copy every text or edit every child element ) are used if no suitable template is found.

The output of the XSLT processor is initially an object model of the output document. This object can be further processed directly via a programming interface (API). Most XSLT processors can also output to one or more files ( serialization ).

XSLT processors initially differ in the supported XSLT and XPath versions (1.0 and / or 2.0). For XSLT 2.0, the XSLT standard also defines the distinction between a basic XSLT processor (full support of the XSLT 2.0 standard) and a schema-sensitive XSLT processor ("schema aware": additional consideration of information from XML schemas in the Processing). The standard-compliant, stable and, thanks to Java, platform-independent Saxon processor is widespread . Many modern web browsers such as Internet Explorer , Mozilla Firefox and Opera have built-in XSLT 1.0 processors so that they can directly display XML documents in XSLT formatting.
