Question

这是我第一次尝试以字符串的形式对从cURL返回的xml执行转换。我有一个我认为正确编写的PHP，因为我至少可以回显$xml_data中包含的字符串。但是，每当我尝试通过浏览器查看php时，我都会得到一个空白页面（和源代码）。我究竟做错了什么？任何指针都会有所帮助和赞赏..

PHP

<?php
$ch = curl_init("http://somewhere.com/deliver_xml.php?release_week=20140126");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$xml_data=curl_exec($ch);
curl_close($ch);

$xmlDoc = new DOMDocument();
$xml->$xml_data;

$xslDoc = new DOMDocument();
$xslDoc->load("new_releases.xsl");

$proc = new XSLTProcessor();
$proc->importStylesheet($xslDoc);

$xmlDoc->loadXML($xml_data);

echo $proc->transformToXML($xmlDoc);

$proc->setParameter('', 'albumid', $_POST["id"]);

?>

XSL（注意这还不完整，此时我只是试图从屏幕上的xml中获取一些数据并设置样式）

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://www.w3.org/1999/xhtml">

   <xsl:output method="html" />

    <xsl:template match="/">
    <html><body>
     <div style="position: relative; font-weight: bold; font-size: 24pt;">
        New music for the week of <xsl:value-of select="release_week_start"/></div>
      <xsl:for-each select="/album">
              <a xmlns="http://www.w3.org/1999/xhtml"
                href="{../@id}.xhtml">
                <xsl:value-of select="album/artist"/>
              </a>
      </xsl:for-each>        
 </body></html>



</xsl:stylesheet>

如果我在php中包含echo $xml_data，我会得到以下xml字符串

<?xml version="1.0"?>

Answer 1

来自http://php.net/manual/en/xsltprocessor.transformtoxml.php

使用libxml_get_last_error()或libxml_get_errors()检索转换中的错误。

使用XSLT和cURL跟踪错误
