sablotron and php have to be correctly linked with iconv library to get this function working
IE on sabotron ./configure :
--with-iconv-prefix=/your/path

I'm running Mandrake Linux v9.1, with Apache 2.0.48 and PHP 4.3.4...I'm have make PHP with XSLT support, and this work fine, expect because a problem...the function xslt_set_encoding don't work, and i have found a solution...simply, type export LDFLAGS=-lstdc++ before start the configure program of PHP. And this will work!

i'm usig it that way:
$ht=xslt_create();
xslt_set_encoding($ht,"ISO-8859-2");
$args = array ( '/_xml' => $xml, '/_xslt' => $xslt);
$result=xslt_process($ht,'arg:/_xml','arg:/_xslt',NULL,$args);
all placed in very nice class ;-)
