 <h3>What Is Xalan?</h3>

 <p>Xalan is an XSLT processor for transforming XML documents
 into HTML, text, or other XML document types.
 It uses for input an XML document and an XSLT stylesheet.
 The engine also supports the entry of top-level stylesheet parameters.
 Documentation exists on how to extend the library with
 your own custom XPath functions.
 </p>
 <p>Xalan-C++ version 1.11 is a robust implementation of the
 W3C Recommendations for
 <a href="http://www.w3.org/TR/xslt">XSL Transformations (XSLT)</a>
 and the
 <a href="http://www.w3.org/TR/xpath">XML Path Language (XPath)</a>.
 It works with the
 <a href="http://xerces.apache.org/xerces-c">Xerces-C++ version 3.1.1</a>
 release of XML parsers.
 The focus for this Xalan release is on bug fixes and
 compatibility with newer development platforms.
 </p>
 <p>The Xalan-C/C++ project creates and distributes a
 standard XSLT library and a simple Xalan command-line
 utility for transforming XML documents.
 </p>
 <p>This project is written in a reduced set of the C++ programming language.
 This makes the library directly usable on numerous platforms.
 A set of 'C' language APIs is also available so that
 XSLT and XPath functionality is easily deployed to 'C' language applications.
 </p>
 <p>
 <a href="samples.html">Sample programs</a> are available
 for you to test and experiment with as you learn the Xalan library.
 </p>
 <p>Some of the <a href="http://www.exslt.org">EXSLT extension functions</a>
 for XPath are available.
 We need to write and validate more of the EXSLT functions.
 Apache also provides some of their own
 <a href="extensionslib.html">XPath extensions</a> for use.
 Documentation and examples are available for you to write
 your own custom <a href="extensions.html">XPath extensions</a>.
 </p>
 <p>There is a library of <a href="extensionslib.html">XPath extensions</a>
 that are provided by the Apache Xalan community.

 <h3>XML Parser Library</h3>

 <p>Xalan-C/C++ uses the The Apache Software Foundation Xerces-C project that implements parsers for XML 1.0 and XML 1.1.
 The following standards as specified by the
 <a href="http://www.w3.org/TR">World Wide Web Consortium (W3C)</a> are implemented by the
 <a href="http://xerces.apache.org/xerces-c">Xerces-C</a> XML parser library.

 <p>The Xerces-C/C++ also supports the <a href="http://sax.sourceforge.net/">SAX 1.0 and SAX 2.0</a> projects.
 SAX is primarily Java based. The Xerces-C/C++ project has implemented a SAX C++ API that looks much like the SAX Java API.
 </p>
 <p>Web Services and Web Security recommendations have been developed by the
 <a href="http://www.w3.org">World Wide Web Consortium (W3C)</a> and
 <a href="http://www.oasis-open.org">OASIS-OPEN</a> Advancing open standards for the information society.
 The Xerces-C/C++ has support for custom entity resolvers which are inherited and
 supported by the Xalan-C/C++ library.
 </p>


 <a name="securityIssues">‌</a>
 <p align="right" size="2">
 <a href="#content">(top)</a>
 </p>
 <h3>Security Issues</h3>

 <p>The Xalan-C/C++ library has hooks so that custom entity resolvers can be deployed.
 The entity resolvers are actually interfaces into the Xerces-C/C++ XML Parser Library.
 Use of trusted entity resolvers greatly increases the security of XML based applications.
 </p>
 <p>The Web Services Architecture uses specifications and recommendations
 that are documented by the following organizations.
 </p>
 <ul>
 <li>World Wide Web Consortium (W3C)<br />
   [<a href="http://www.w3.org">http://www.w3.org]</a>]</li>
 <li>Advancing open standards for the information society (OASIS-OPEN)<br />
   [<a href="http://www.oasis-open.org">http://www.oasis-open.org</a>]</li>
 <li>The Sourceforge SAX Project (SAX1, SAX2)<br />
   [<a href="http://sax.sourceforge.net">http://sax.sourceforge.net</a>]</li>
 <li>Internet Engineering Task Force (IETF)<br />
   [<a href="http://www.ietf.org">http://www.ietf.org</a>]</li>
 </ul>
 <p>There are some <a href="secureweb.html">architecture security</a> issues
 that should be addressed by any XML parser or XSLT transformation application.
 Other than validating and cleaning the content of XML elements,
 the access to untrusted external entities is a big problem for security management.
 </p>
 <p>The "Xalan" comman-line transformation program does not deploy
 an OASIS catalog or perform other security measures.
 URLs are resolved using the system directory of the local machine
 and DNS to resolve host locations.
 The "Xalan" program should be used only with
 trusted XSLT stylesheets and XML documents on a trusted computer.
 </p>
 <p>A future release of the "Xalan" command-line transformation program
 may include support for an OASIS entity resolver catalog.
 </p>
 <p>Information on creating Secure Web Service Applications is useful for review.
 This <a href="secureweb.html">security overview document</a> goes beyond the scope of
 XSLT transformations and asks many pertinent security based questions.
 </p>


 <a name="getstarted">‌</a>
 <p align="right" size="2">
 <a href="#content">(top)</a>
 </p>
 <h3>Getting Started</h3>

 <p>The source code and documentation are delivered in separate packages.
 Binary packages comprise the compiled libraries, the Xalan command line utility, and the C/C++ header files.
 The documentation package contains the pre-built documentation.
 The source package contains the sources to build everything.
 </p>
 <p>The current Xalan-C/C++ Version 1.11 is compatible with the stable releases of
 <a href="http://xerces.apache.org/xerces-c">Xerces-C/C++</a> Version 3.0 and newer. The current stable release for Xerces-C/C++ is 3.1.1.
 </p>
 <p>The previous Xalan-C/C++ Version 1.10 works with Xerces-C/C++ Versions 2.7.0 and 2.8.0.
 </p>
 <p>If you are having problems using the product,
 send your comments to the <a href="mailto:c-users@xalan.apache.org">xalan-c-users</a> mail list.
 </p>
 <p>If you think a change needs to be made or have suggestions for future releases,
 send your comments to the <a href="mailto:dev@xalan.apache.org">xalan-dev</a> mail list.
 </p>
 <p>Binary releases are not yet available.
 We would like to distribute Xalan-C/C++ Version 1.11 binary releases
 using the same platforms specified for the compatible Xerces-C binary packages.
 </p>


 <a name="getWhatNeeded">‌</a>
 <p align="right" size="2">
 <a href="#content">(top)</a>
 </p>
 <h3>Getting What You Need</h3>

 <p>What you need depends whether you plan to
 build from the sources or download prebuilt packages.
 </p>
 <p>The development platform used to build the Xalan-C/C++ (XSLT) library
 should be the same as the platform used to build the Xerces-C/C++ (XML) parser library.
 </p>
 <p>Xalan-C/C++ (XSLT) library requires a working Xerces-C/C++ (XML) parser library.
 The supported versions of Xerces-C/C++ version 3.0 or newer. Version 3.1.1
 is recommended.
 </p>
 <p>If you are ambitious and willing to experiment,
 you can download the bleeding edge development from the
 Apache Software Foundation subversion repositories.
 Use your favorite subversion 'svn' utility for download.

	<h3>What Is Xalan?</h3>

	<p>Xalan is an XSLT processor for transforming XML documents
	into HTML, text, or other XML document types.
	It uses for input an XML document and an XSLT stylesheet.
	The engine also supports the entry of top-level stylesheet parameters.
	Documentation exists on how to extend the library with
	your own custom XPath functions.
	</p>
	<p>Xalan-C++ version 1.11 is a robust implementation of the
	W3C Recommendations for
	<a href="http://www.w3.org/TR/xslt">XSL Transformations (XSLT)</a>
	and the
	<a href="http://www.w3.org/TR/xpath">XML Path Language (XPath)</a>.
	It works with the
	<a href="http://xerces.apache.org/xerces-c">Xerces-C++ version 3.1.1</a>
	release of XML parsers.
	The focus for this Xalan release is on bug fixes and
	compatibility with newer development platforms.
	</p>
	<p>The Xalan-C/C++ project creates and distributes a
	standard XSLT library and a simple Xalan command-line
	utility for transforming XML documents.
	</p>
	<p>This project is written in a reduced set of the C++ programming language.
	This makes the library directly usable on numerous platforms.
	A set of 'C' language APIs is also available so that
	XSLT and XPath functionality is easily deployed to 'C' language applications.
	</p>
	<p>
	<a href="samples.html">Sample programs</a> are available
	for you to test and experiment with as you learn the Xalan library.
	</p>
	<p>Some of the <a href="http://www.exslt.org">EXSLT extension functions</a>
	for XPath are available.
	We need to write and validate more of the EXSLT functions.
	Apache also provides some of their own
	<a href="extensionslib.html">XPath extensions</a> for use.
	Documentation and examples are available for you to write
	your own custom <a href="extensions.html">XPath extensions</a>.
	</p>
	<p>There is a library of <a href="extensionslib.html">XPath extensions</a>
	that are provided by the Apache Xalan community.

	<a name="securityIssues">‌</a>
	<p align="right" size="2">
	<a href="#content">(top)</a>
	</p>
	<h3>Security Issues</h3>

	<p>The Xalan-C/C++ library has hooks so that custom entity resolvers can be deployed.
	The entity resolvers are actually interfaces into the Xerces-C/C++ XML Parser Library.
	Use of trusted entity resolvers greatly increases the security of XML based applications.
	</p>
	<p>The Web Services Architecture uses specifications and recommendations
	that are documented by the following organizations.
	</p>
	<ul>
	<li>World Wide Web Consortium (W3C)<br />
	[<a href="http://www.w3.org">http://www.w3.org]</a>]</li>
	<li>Advancing open standards for the information society (OASIS-OPEN)<br />
	[<a href="http://www.oasis-open.org">http://www.oasis-open.org</a>]</li>
	<li>The Sourceforge SAX Project (SAX1, SAX2)<br />
	[<a href="http://sax.sourceforge.net">http://sax.sourceforge.net</a>]</li>
	<li>Internet Engineering Task Force (IETF)<br />
	[<a href="http://www.ietf.org">http://www.ietf.org</a>]</li>
	</ul>
	<p>There are some <a href="secureweb.html">architecture security</a> issues
	that should be addressed by any XML parser or XSLT transformation application.
	Other than validating and cleaning the content of XML elements,
	the access to untrusted external entities is a big problem for security management.
	</p>
	<p>The "Xalan" comman-line transformation program does not deploy
	an OASIS catalog or perform other security measures.
	URLs are resolved using the system directory of the local machine
	and DNS to resolve host locations.
	The "Xalan" program should be used only with
	trusted XSLT stylesheets and XML documents on a trusted computer.
	</p>
	<p>A future release of the "Xalan" command-line transformation program
	may include support for an OASIS entity resolver catalog.
	</p>
	<p>Information on creating Secure Web Service Applications is useful for review.
	This <a href="secureweb.html">security overview document</a> goes beyond the scope of
	XSLT transformations and asks many pertinent security based questions.
	</p>

	<p align="right" size="2">
	<a href="#content">(top)</a>
	</p>
	<h3>Getting Started</h3>

	<p>The source code and documentation are delivered in separate packages.
	Binary packages comprise the compiled libraries, the Xalan command line utility, and the C/C++ header files.
	The documentation package contains the pre-built documentation.
	The source package contains the sources to build everything.
	</p>
	<p>The current Xalan-C/C++ Version 1.11 is compatible with the stable releases of
	<a href="http://xerces.apache.org/xerces-c">Xerces-C/C++</a> Version 3.0 and newer. The current stable release for Xerces-C/C++ is 3.1.1.
	</p>
	<p>The previous Xalan-C/C++ Version 1.10 works with Xerces-C/C++ Versions 2.7.0 and 2.8.0.
	</p>
	<p>If you are having problems using the product,
	send your comments to the <a href="mailto:c-users@xalan.apache.org">xalan-c-users</a> mail list.
	</p>
	<p>If you think a change needs to be made or have suggestions for future releases,
	send your comments to the <a href="mailto:dev@xalan.apache.org">xalan-dev</a> mail list.
	</p>
	<p>Binary releases are not yet available.
	We would like to distribute Xalan-C/C++ Version 1.11 binary releases
	using the same platforms specified for the compatible Xerces-C binary packages.
	</p>

	</p>
	<h3>Getting What You Need</h3>

	<p>What you need depends whether you plan to
	build from the sources or download prebuilt packages.
	</p>
	<p>The development platform used to build the Xalan-C/C++ (XSLT) library
	should be the same as the platform used to build the Xerces-C/C++ (XML) parser library.
	</p>
	<p>Xalan-C/C++ (XSLT) library requires a working Xerces-C/C++ (XML) parser library.
	The supported versions of Xerces-C/C++ version 3.0 or newer. Version 3.1.1
	is recommended.
	</p>
	<p>If you are ambitious and willing to experiment,
	you can download the bleeding edge development from the
	Apache Software Foundation subversion repositories.
	Use your favorite subversion 'svn' utility for download.
