我正在根据SVG规范验证SVG文档（我相信它是有效的）。我在PHP中使用XMLReader，并且宁愿坚持使用XMLReader，因为我将在其他地方使用XMLReader;如果有其他基于流的读者会更容易/更好地做到这一点，请告诉我。
好的，这是一些代码：
// Set some values for the purpose of this example
$this->path = '/Users/jon/Development/Personal/Visualised/master/test-assets/import-png.svg';
$xsdPath = '/Users/jon/Development/Personal/Visualised/master/test-assets/xsd/SVG.xsd';
$reader = new XMLReader();
$reader->open($this->path);
$valid = $reader->setSchema($xsdPath);
$reader->close();
好的，我在xsd文件夹中的XSD文件是：
解析器似乎从第一个导入第二个和第三个XSD - 我希望任何依赖项存储在磁盘上，而不是从互联网上检索。
好的，这是输出：
XMLReader::setSchema(): Element '{http://www.w3.org/2001/XMLSchema}import': Skipping import of schema located at '/Users/jon/Development/Personal/Visualised/master/test-assets/xsd/xml.xsd' for the namespace 'http://www.w3.org/XML/1998/namespace', since this namespace was already imported with the schema located at 'http://www.w3.org/2001/xml.xsd'. in /Users/jon/Development/Personal/Visualised/master/lib/Visualised/Document.php on line 45

似乎我可能在某处导入了错误版本的架构 - 我通过网络搜索找到了所有XSD文档。有什么想法吗？
编辑：最后一个错误表明应该在阅读文档之前设置架构。好的，所以我已将代码更改为：
$reader = new XMLReader();
$valid = $reader->setSchema($xsdPath);
$reader->open($this->path);
$reader->close();
- 一些初始警告，但我仍然得到Unable to set schema一个。
