PHP：XSLT 处理器在 Windows WRT 到 Linux 中的不同行为

Question

我有这个 php 片段：

$xsltPath = $argv[1];
$xmlPath = $argv[2];

$xslt = file_get_contents($xsltPath);
$xml = file_get_contents($xmlPath);

$templateCMSObj = new \DOMDocument();
$templateCMSObj->loadXML($xslt);
$ekbXMLObj = new \DOMDocument();
$ekbXMLObj->loadXML($xml);
$proc = new \XSLTProcessor();
$proc->importStylesheet($templateCMSObj);
$html = $proc->transformToXML($ekbXMLObj);
echo($html);
exit;

它只是将 XSLT 应用于给定的 XML 文档。

当我将下面的 XSLT 应用于同一个 XML 文档时，我得到了 Windows 与 Linux PHP 版本不同的行为。

这里是 php 和 libxml 版本详细信息：

Windows:

而 XML 文档在 win 和 linux 中给出了不同的结果 XSLT:

Linux输出 这是在 Linux:

问题在于 NaN put 而不是相对索引：它肯定与 xsl:number 元素有关，但我不知道如何解决这个问题...

接受答案后编辑

通过将 xsl:number count 属性更改为 * 而不是 node() xslt 模板在 Win 和 Linux.[=25 上都可以正常工作=]

这是更新后的代码：

Answer 1

在 xsl:number 的 select 属性中，使用 * 而不是 node()。

当您使用 node() 时，它可以是元素、文本、注释或处理指令节点。

当您使用 * 时，那只是一个元素。这在您使用 xsl:number.

时更有意义
