| <s2 title="Introduction"> |
| <p>&xslt4c; (named after a rare musical instrument) implements the <resource-ref idref="XSLT"/> and the |
| <resource-ref idref="XPath"/>. XSLT is the first part of the XSL stylesheet language for XML. It includes the XSL |
| Transformation vocabulary and XPath, a language for addressing parts of XML documents. For links to background materials, |
| discussion groups, frequently asked questions, and tutorials on XSLT, see <link anchor="uptospeed">Getting up |
| to speed with XSLT</link>.</p> |
| <note>XSL also includes a vocabulary for formatting documents, which is not part of &xslt4c;. |
| For more information, see <jump href="http://www.w3.org/TR/xsl/">W3C XSL Working Draft</jump> and the <jump |
| href="http://xml.apache.org/fop">Apache XML FOP (Formatting Objects Project)</jump>.</note> |
| <p>You use the XSLT language to compose XSL stylesheets. An XSL stylesheet contains instructions for |
| transforming XML documents from one document type to another document type (XML, HTML, or other). In structural |
| terms, an XSL stylesheet specifies the transformation of one tree of nodes (the XML input) into another tree of nodes |
| (the output or transformation result).</p> |
| <note>The XSL stylesheet may generate and refer to cascading style sheets (<jump |
| href="http://www.w3.org/Style/CSS/">CSS</jump>) as part of its output.</note> |
| <p>In the following example, the foo.xsl stylesheet is used to transform foo.xml into foo.out:</p> |
| <p>foo.xml:</p> |
| <source><?xml version="1.0"?> |
| <doc>Hello</doc></source> |
| <p>foo.xsl:</p> |
| <source><?xml version="1.0"?> |
| <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> |
| <xsl:template match="doc"> |
| <out><xsl:value-of select="."/></out> |
| </xsl:template> |
| </xsl:stylesheet></source> |
| <p>foo.out:</p> |
| <source><out>Hello</out></source> |

| <li>&xslt4c; incorporates the <resource-ref idref="XPath"/>.<br/><br/></li> |
| <li>&xslt4c; uses <jump href="http://xml.apache.org/xerces-c/index.html">&xml4c;</jump> to parse XML documents and XSL |
| stylesheets.<br/><br/> |
| The input may appear in the form of a file or URL, a stream, or a <resource-ref idref="DOM"/>. |
| &xslt4c; performs the transformations specified in the XSL stylesheet and produces a file, a stream, or a DOM as you |
| specify when you set up the transformation.<br/><br/></li> |
| <li>Along with a complete API for performing transformations in your C++ applications, &xslt4c; provides a <link |
| idref="commandline">command line</link> utility for convenient file-to-file transformations.<br/><br/></li> |

| <gloss> |
| <label>XSLT Namespace</label> |
| <item>The <jump href="http://www.w3.org/TR/REC-xml-names/">XML namespace</jump> for XSLT. An XML namespace is a |
| collection of element and attribute names, identified by a Unique Resource Identifier (URI), which often takes the form of |
| a URL, but is really just a unique string, not a pointer to a web page. The XSLT namespace URI is |
| http://www.w3.org/1999/XSL/Transform. In each XSLT stylesheet, you must declare this namespace in the stylesheet element |
| tag and bind it to a local prefix. Like the XSLT specification, we always use xsl as the XSLT namespace prefix in our |
| descriptions and examples, although you are free to bind any prefix to this namespace.<br/><br/></item> |
| |
| <label>XSL Instruction</label> |
| <item>Any tag associated with the XSLT namespace.<br/><br/></item> |
| |
| <label>Template</label> |
| <item>An element, usually with child elements, that specifies a "rule" or set of |
| instructions to perform when a particular kind of node is encountered in the source tree.<br/><br/></item> |
| |
| <label>XSL Template Instruction</label> |
| <item>Any tag that occurs inside an xsl:template element and is associated with the XSLT namespace.<br/><br/></item> |
| |
| <label>Source Tree</label> |
| <item>The XML tree input to the XSL process.<br/><br/></item> |
| |
| <label>Result Tree</label> |
| <item>The tree that is output by the XSL process.<br/><br/></item> |
| |
| <label>Stylesheet Tree</label> |
| <item>The stylesheet tree produced from the XSL file.<br/><br/></item> |
| |
| <label>Match Pattern</label> |
| <item>The part of a template that defines the kind(s) of nodes to which the template applies.<br/><br/></item> |
