- " a<! [CDATA [<]]>b "
What is the difference between XSL and XSLT?
XSLT - Basic Principle
- A style sheets describes transformation rules
- A transformation rule: a pattern + a template
- Pattern: a configuration in the source tree
- Template: a structure to be instantiated in the result tree
- When a pattern is matched in the source tree, the corresponding pattern is generated in the result tree
How to use XSLT to transform XML?
XSLT Transformations with the XML Module - Mule 4
- Externalizing the XSL Style Sheet to a Separate File. In a more complex use case, the script you use might depend on some external condition. ...
- Using Context Properties. The XML module, like the XSL language, provides context properties that can pass parameters to the transformation.
- Output MIME Type. ...
How to compare two XML objects with XSLT?
XSLT is far more sophisticated than CSS. With XSLT you can add/remove elements and attributes to or from the output file. You can also rearrange and sort elements, perform tests and make decisions about which elements to hide and display, and a lot more.
What is XSLT used for?
The Extensible Stylesheet Language Transformation (XSLT) standard specifies a language definition for XML data transformations. XSLT is used to transform XML documents into XHTML documents, or into other XML documents.
What is XSLT and how does it work?
XSLT Processor takes the XSLT stylesheet and applies the transformation rules on the target XML document and then it generates a formatted document in the form of XML, HTML, or text format. This formatted document is then utilized by XSLT formatter to generate the actual output which is to be displayed to the end-user.
What is XPath what is it used for?
The XML Path Language (XPath) is used to uniquely identify or address parts of an XML document. An XPath expression can be used to search through an XML document, and extract information from any part of the document, such as an element or attribute (referred to as a node in XML) in it.
What is XSLT in Java?
XSL stands for EXtensible Stylesheet Language. It is a styling language for XML just like CSS is a styling language for HTML. XSLT stands for XSL Transformation. It is used to transform XML documents into other formats (like transforming XML into HTML).
What is XSLT with an example?
An XSLT stylesheet starts with the xsl:stylesheet element, which contains all the templates used to create the final output. The example above has two templates - one that matches the root node and one that matches Author nodes.

What is XPath example?
XPath uses path expressions to select nodes or node-sets in an XML document. These path expressions look very much like the expressions you see when you work with a traditional computer file system. XPath expressions can be used in JavaScript, Java, XML Schema, PHP, Python, C and C++, and lots of other languages.
What is XPath and types?
XPath stands for XML(eXtensible Markup Language) Path. Using XPath we can navigate to any element in an XML document. Since XML is a component of HTML, so XPath's can be used to find web elements on any web page. There are two types of XPath: 1.
What is XPath in JSON?
XPath uses it to iterate over element collections and for predicates. In JavaScript and JSON it is the native array operator. | [,] Union operator in XPath results in a combination of node sets.

The XML document is the input document used for transformation. ... On the menu bar, choose XML > Start XSLT Without Debugging.
Why XSLT is important for XML?
XSLT enables you to transform an XML document into another markup language. The most common use of XSLT is to transform information to HTML for display on the Web. But XSLT can also be used to convert information from XML into markup for wireless display, for transmission to PDAs and web-enabled cell phones.
Is XSLT a programming language?
From a programmer's point of view, XSLT is a programming language for processing XML data — that is, transforming XML documents. As such, it supports the following: A small set of flexible data types: Boolean, number, string, node-set, and external objects.
How does XSLT work?
XSLT Working: In the transformation process, XSLT uses XPath to define parts of the source document that should match one or more predefined templates. When a match is found, XSLT will transform the matching part of the source document into the result document.
What is XPath in XML?
XPath can be used to navigate through elements and attributes in an XML document. It allows XML authors to link to very specific locations within an XML document. XPath uses "path like" syntax to identify and navigate nodes in an XML document. XPath contains over 200 built-in functions.
What is XSL transformation?
XSL Transformations (XSLT) XSLT is an XML-based language that transforms an XML documents and generates output into a different format such as HTML, XHTML or PDF. XSLT is an extension of XSL, which is a stylesheet definition language for XML. XSLT is the most important part of XSL.
What is XSL-FO?
XSLT – For transforming XML document. XPATH – For navigating in XML document. XSL-FO – For formatting XML document. XSL has two attributes.
Why was XSL developed?
W3C developed XSL because an XML based stylesheet language was needed to transform XML documents. XSL act as an intermediary between the XML elements and Web browser. It tells the browser how to display the various elements. XSL used to performs following operations, like. Support for browsing, printing, and rendering.
What are predicates in XPath?
Predicates are also used to find a specific node or a node that contains a specific value. Predicates are always embedded in square brackets. XPath wildcards can be used to select unknown XML nodes and also the use of | operator in an XPath expression select several paths. ADD COMMENT.
What is XML in web?
XML is a markup language based on simple, platform-independent rules for processing and displaying textual information in a structured way.
How does XPath work?
XPath navigates down to elements in an XML document similar to the way you change directories in MS-DOS or a Linux shell. You can change directories on your computer and see other directories or files in these directories. Likewise, XML elements can be navigated to find other elements or data in them.
What is XPath in BPEL?
Using our analogy, XPath is like a SQL-select statement. It is used to select information from data—our invoice XML document in this case. For BPEL developers, it is useful to know that XPath is used in all assignments. For BPEL developers and everyone else, you should know that it is used in most all XSL statements.
What is a namespace in XML?
Namespaces are used to classify elements and attributes in an XML document and are defined in a namespace attribute in the document. The namespace attribute always starts with xmlns, short for xml namespace. It can also specify a prefix like xmlns:tns.
What does xpath return?
will return an integer (if possible) or a string. There are conversion functions, like string (xpath) and integer (xpath) that can force the result into a certain type, but they aren’t usually needed. If the data can fit into a string or integer, it will return that type; otherwise, it will return a node or node set.
What is XML representation?
XML is a representation of data with simple notations to use. The notations consist of elements and attributes. Elements start with a notation such as <invoice> and close with the notation </invoice>. Elements can contain attributes, such as <invoice pk=”23”> or other elements or data as shown here.
Can variables be defined in XSL?
Variables can be defined almost anywhere in an XSL document. If you place the definition before the initial template statement <xsl:template select="/" ... >, it acts like a global variable. If you use it right after a statement, for example <xsl:for-each>, it creates a useful local reference to a value for operating on data specified in the for-each loop.
Can XML elements be navigated?
Likewise, XML elements can be navigated to find other elements or data in them . So elements are like directories and files are like data in the elements. One exception to this analogy is that elements can also contain attributes. For now, think of attributes like metadata for the element.
What is XPath in XML?
XPath uses path expressions to navigate in XML documents . XPath contains a library of standard functions. XPath is a major element in XSLT and in XQuery. XPath is a W3C recommendation.
What is XPath expression?
XPath uses path expressions to select nodes or node-sets in an XML document. These path expressions look very much like the expressions you see when you work with a traditional computer file system. XPath expressions can be used in JavaScript, Java, XML Schema, PHP, Python, C and C++, and lots of other languages.
What is an XSLT stylesheet?
An explicitly declared XSLT stylesheet is comprised of a distinct wrapper element containing the stylesheet specification. This wrapper element must be an XSLT instruction named either stylesheet or transform, thus it must be qualified by the prefix associated with the XSLT namespace URI. This wrapper element is the document element in a standalone stylesheet, but may in other cases be embedded inside an XML document.
What prefix is used for XSLT?
Any prefix can be used for XSLT instructions, though convention often sees xsl: as the prefix value. Line 7 contains the only XSLT instruction in the instance. The xsl:value-of instruction uses an XPath expression in the select= attribute to calculate a string value from our source information.
Where are XSLT instructions detected?
XSLT instructions are only detected in the stylesheet tree and are not detected in the source tree . Instructions are specified using the namespace prefix associated with the XSLT namespace URI. The XSLT Recommendation describes the behavior of the XSLT processor for each of the instructions defined based on the instruction's element type (name).
Can you push a stylesheet?
We are not obliged to use only one approach when we write our stylesheets. It is very appropriate to push where the order is dictated by the source information and to pull when responding to a push where the order is known by the stylesheet. The most common use of this combination in a template is localized pull access to values that are relative to the focus being matched by nodes being pushed.
