Transforming XML with XSLT
Extensible Stylesheet Language Transformations (XSLT) is a language for transform-
ing XML documents into different XML, HTML, or any other format. For example,
many web sites offer several formats of their content—HTML, printable HTML, and
WML (Wireless Markup Language) are common. The easiest way to present these
multiple views of the same information is to maintain one form of the content in
XML and use XSLT to produce the HTML, printable HTML, and WML.
PHP’s XSLTextension uses the Sablotron C library to provide XSLTsupport.
Sablotron does not ship with PHP—you’ll need to download it from
http://www.gin-
gerall.com
, install it, and then rebuild PHP with the
--enable-xslt --with-xslt-
sablot
option to
configure
.
PHP’s XSLTsupport is still experimental at the time of writing, and the exact imple-
mentation details may change from what is described here. However, this description

function handle_errors ($error, $message, $filename, $line) {
ob_end_clean( );
echo "$message in line $line of $filename
element, we register the error handler and
begin output buffering. If we cannot connect to the database (or if anything else goes
wrong in the subsequent PHP code), the heading and table are not displayed.
Instead, the user sees only the error message, as shown in Figure 13-1. If no errors
are raised by the PHP code, however, the user simply sees the HTML page.
