我正在尝试使用 Php XSLTProcessor将 XSL-FO 文件转换为 HTML 。我在这里做什么：

public static function toHTML($xml)
{
 // init
 $xp    = new XSLTProcessor();
 $xmlDoc   = new Mv_Dom_Document();
 $xmlDoc->loadXML($xml);
 $dirXslt  = $GLOBALS['G_config']['XSLT_STYLESHEETS'].'fo2html/';
 $aXsltSS  = GestionFichiers::getDirContent($dirXslt);

 // chargement des feuilles de styles XSLT pour la conversion
 foreach ($aXsltSS AS $stylesheet) {
  $xslDoc  = new Mv_Dom_Document($stylesheet->getRealPath());
  $xp->importStylesheet($xslDoc);
  unset($xslDoc);
 }

 // transformation HTML > XML
 return $xp->transformToXML($xmlDoc);
}

但我在转换时收到以下错误：

ERREUR - XSLTProcessor::transformToXml() [<a href='xsltprocessor.transformtoxml'>xsltprocessor.transformtoxml</a>]: xsltApplySequenceConstructor: apply-templates was not compiled
ERREUR - XSLTProcessor::transformToXml() [<a href='xsltprocessor.transformtoxml'>xsltprocessor.transformtoxml</a>]: xsltApplySequenceConstructor: apply-templates was not compiled
ERREUR - XSLTProcessor::transformToXml() [<a href='xsltprocessor.transformtoxml'>xsltprocessor.transformtoxml</a>]: xsltApplySequenceConstructor: if was not compiled

当我尝试直接使用 apache fop 扩展来转换我的 XSL-FO 时，转换成功，那么为什么 php 失败了？

PS：当我尝试使用 XSLTProcessor 将其他东西转换为具有正确样式表的 HTML2FO 时，我没有遇到任何问题。

之前谢谢。

编辑：样式表已从http://svn.apache.org/repos/asf/db/derby/docs/trunk/lib/fo2html.xsl上的 apache svn 下载，这里是我一直使用的输入示例测试：
