我有时在 Kernow 中使用 saxon 处理器测试我的 xslt 样式表。我总是使用 xslt 1.0,因为 simplexml 甚至 simpledom 只能执行 xslt 1.0。以下样式表在 php 中不起作用:
$tagsXml=simpledom_load_file('...xml');
$dom_sxe=dom_import_simplexml($tagsXml);
$dom = new DOMDocument('1.0');
$dom_sxe = $dom->importNode($dom_sxe, true);
$dom_sxe = $dom->appendChild($dom_sxe);
$proc = new XSLTProcessor();
$xsl = new DOMDocument;
$xsl->load('...xslt');
$proc->importStylesheet($xsl);
$newXml = $proc->transformToXml($dom);
那就是样式表是 php 抛出编译错误,无法编译 when 语句<xsl:when test="count($ctag/ancestor::*[local-name()=current()/local-name() and text()=current()/text()]|$ctag/descendant::*[local-name()=current()/local-name() and text()=current()/text()])>0">

我知道这个模板并不完美,也不容易理解。在php中遇到此类问题的任何经验?感谢您的帮助!
