How XSLT Works — Lenz Consulting Group, Inc. By Evan Lenz This is Chapter 3 from XSLT 1.0 Pocket Reference.
I chose this excerpt for its standalone value in quickly describing XSLT’s processing model. Take a few moments to master the concepts explained here, and you’ll save yourself a lot of grief in the future. XSLT How To's. Xsl:namespace in XSLT 2.0. RE: [xsl] insert a tab/space characters. Concatenation - XSLT concat string, remove last comma. The Extensible Stylesheet Language Family (XSL) XSLT Chapter 8: Advanced Pattern Matching. XSLT. XSLT (Extensible Stylesheet Language Transformations) is a language for transforming XML documents into other XML documents, or other objects such as HTML for web pages, plain text or into XSL Formatting Objects which can then be converted to PDF, PostScript and PNG. The original document is not changed; rather, a new document is created based on the content of an existing one. Typically, input documents are XML files, but anything from which the processor can build an XQuery and XPath Data Model can be used, for example relational database tables, or geographical information systems. XSLT is a Turing-complete language, meaning it can specify any computation that can be performed by a computer.

Processor implementations Performance Installing an XSLT processor. This section describes how to install the free processors.
The commercial processors are assumed to provide instructions and support. You should check the details with each product that is described here, as the steps may change over time. The installation of xsltproc is platform dependent since it is a compiled C program. You will need a C compiler and associated Make tools unless you are using Windows. Macintosh users can download binaries from Installing xsltproc on Windows You can download precompiled versions for Windows from Igor Zlatkovic's website: That page also describes how to install the files and use xsltproc on Windows.
Once you have unpacked them, your environment's PATH variable must include the locations of the command files like xsltproc.exe and the set of library files named with the .dll suffix. You will know it is working if you can execute the following command in a Command shell to list the version information: xsltproc -version Installing xsltproc on Cygwin Note. XSLT basics.

I have seen the XSLT language evolving from version 1.0 to 2.0, therefore I find it quite interesting to compare the two language versions. How old are these two languages, and a little bit of history? XSL Transformations (XSLT) Version 2.0. This section provides a checklist of progress against the published XSLT 2.0 Requirements document (see [XSLT 2.0 Requirements]).
Requirement 1. XQuery 1.0 and XPath 2.0 Functions and Operators (Second Edition) See [Working With Timezones] for a disquisition on working with date and time values with and without timezones. 10.1 Duration, Date and Time Types The operators described in this section are defined on the following date and time types:
XQuery 1.0 and XPath 2.0 Data Model (XDM) (Second Edition) This section describes the constraints on instances of the data model.
This document describes how to construct an instance of the data model from an infoset ([Infoset]) or a Post Schema Validation Infoset (PSVI), the augmented infoset produced by an XML Schema validation episode. An instance of the data model can also be constructed directly through application APIs, or from non-XML sources such as relational tables in a database. Regardless of how an instance of the data model is constructed, every node and atomic value in the data model must have a typed-value that is consistent with its type. The data model supports some kinds of values that are not supported by [Infoset]. Examples of these are document fragments and sequences of Document Nodes. 3.3 Construction from a PSVI An instance of the data model can be constructed from a PSVI, whose element and attribute information items have been strictly assessed, laxly assessed, or have not been assessed.
XSL Transformations (XSLT) Version 3.0. Saxon Running XSLT from the Command Line. A command is available to apply a given stylesheet to a given source XML document.
For simple transformations on the Java platform, use the command: java net.sf.saxon.Transform -s:source -xsl:stylesheet -o:output where source, stylesheet, and output are the source XML file, the XSLT stylesheet,B and the output file respectively. For the .NET platform, the command is simply: Re: [xsl] replacing nodes during xsl:copy-of. Namespaces in XSLT — Lenz Consulting Group, Inc. By Evan Lenz Now that we’ve covered what namespaces are for and how they work, let’s take a look at how they are handled in XPath and XSLT.
Namespace concerns in XSLT can be broadly divided into two categories: Dealing with namespaces in the input document, or processing namespaces; and Dealing with namespaces in the output document, or constructing namespaces. In the next two sections, we’ll cover each of these in turn. Table of Contents Processing Namespaces This section concerns how namespaces are represented in the XPath data model and how the XPath language allows you to access the information in that data model. Selecting elements and attributes by name In XPath, to select an element named foo, you (unsurprisingly) use the name test foo.
The key thing to remember is that what prefix is (or isn’t) used in the source document is completely independent of what prefix you use in your stylesheet.
