警告：DOMDocument::loadXML()：需要开始标记，“<” 在实体中找不到

Question

我们从 .xml 文件导入产品

\n\n

为了正确导入产品，我们首先必须创建一个 .xsl 文件，该文件将 .xml 文件从链接 URL 转换为我们的要求。

\n\n

.xml 文件的链接如下所示：\n https://www.importfilexml.de/restful/export/api/products.xml?acceptedlocales=en_US&output-filetype=xml

\n\n

当我粘贴带有标签的链接时，例如选择一个品牌：\n https://www.importfilexml.de/restful/export/api/products.xml?acceptedlocales=en_US&output-filetype=xml&tag_1=Love+Moschino

\n\n

然后工作正确。但是当我将链接粘贴到完整产品目录时：\n https://www.importfilexml.de/restful/export/api/products.xml?acceptedlocales=en_US&output-filetype=xml

\n\n

Then during validate convert from .xsl to .xml I get issue:\nWarning: DOMDocument::loadXML(): Start tag expected, \'<\' not found in Entity, line: 1 in /home/usr/domains/mywebsite.pl/public_html/vendor/firebear/importexport/Model/Output/Xslt.php on line 34\n

\n\n

代码文件.xslt.php：

\n\n

    /**\n     * @param $file\n     * @param $xsl\n     * @return string\n     * @throws \\Magento\\Framework\\Exception\\LocalizedException\n     */\n    public function convert($file, $xsl)\n    {\n        if (!class_exists(\'\\XSLTProcessor\')) {\n            throw new LocalizedException(__(\n                \'The XSLTProcessor class could not be found. This means your PHP installation is missing XSL features.\'\n            ));\n        }\n        $xmlDoc = new \\DOMDocument();\n\n        $xmlDoc->loadXML($file, LIBXML_COMPACT | LIBXML_PARSEHUGE | LIBXML_NOWARNING);\n\n        $xslDoc = new \\DOMDocument();\n        $xslDoc->loadXML($xsl, LIBXML_COMPACT | LIBXML_PARSEHUGE | LIBXML_NOWARNING);\n\n        $proc = new \\XSLTProcessor();\n        $proc->registerPHPFunctions();\n        $proc->importStylesheet($xslDoc);\n        try {\n            $newDom = $proc->transformToDoc($xmlDoc);\n        } catch (\\Exception $e) {\n            throw new LocalizedException(__("Error : " . $e->getMessage()));\n        }\n\n        return $newDom->saveXML();\n    }\n}\n

\n\n

.xml：

\n\n

Answer 1

我认为错误不在 XSLT 中，而只是在您使用 PHP DOMDocument API 时，它有两种方法，一种称为“load如果您有要加载的 XML 或 XSLT 的文件名、文件路径或 URI，则应该使用” ，loadXML如果您有一个包含要解析的 XML 或 XSLT 代码的字符串，则应该使用另一个调用。

您收到的错误建议您使用loadXMLXML 或 XSLT 代码，但不要传入 XML 或 XSLT 代码，而是使用 XML 或 XSLT 代码的文件名、路径或 URI。为此，您应该使用该load方法。

请参阅http://sandbox.onlinephpfunctions.com/code/f080d3aedcc93d591018902724b7846eb063d36b，它演示了$doc->loadXML('foo.xml')生成错误DOMDocument::loadXML(): Start tag expected, '<' not found in Entity，同时$doc->loadXML('<root>test</root>');可以正常工作。因此，将您的loadXML调用更改为loadPHP 代码中的调用。
