我正在使用W3验证器API,我得到了这种响应:
<?xml version="1.0" encoding="UTF-8"?>

<m:warningcount>0</m:warningcount>
<m:warninglist>
</m:warninglist>
</m:warnings>
</m:markupvalidationresponse>
</env:Body>
</env:Envelope>
如何从那里提取一些变量?
我需要validity
,errorcount
,如果可能,还需要错误列表:line
,col
和message
:)
有一种简单的方法吗?

您可以将XML字符串加载到SimpleXMLElement
simplexml_load_string
,然后使用XPath查找属性。在使用XPath之前注册registerXPathNamespace
涉及的名称空间非常重要。
$xml = file_get_contents('example.xml'); // $xml should be the XML source string
$doc = simplexml_load_string($xml);
$doc->registerXPathNamespace('m', 'http://www.w3.org/2005/10/markup-validator');
$nodes = $doc->xpath('//m:markupvalidationresponse/m:validity');
$validity = strval($nodes[0]);
echo 'is valid: ', $validity, "\n";
$nodes = $doc->xpath('//m:markupvalidationresponse/m:errors/m:errorcount');
$errorcount = strval($nodes[0]);
echo 'total errors: ', $errorcount, "\n";
$nodes = $doc->xpath('//m:markupvalidationresponse/m:errors/m:errorlist/m:error');
foreach ($nodes as $node) {
$nodes = $node->xpath('m:line');
$line = strval($nodes[0]);
$nodes = $node->xpath('m:col');
$col = strval($nodes[0]);
$nodes = $node->xpath('m:message');
$message = strval($nodes[0]);
echo 'line: ', $line, ', column: ', $col, ' message: ', $message, "\n";
}

您应该首先使用SOAP库来实现此目的。你可以尝试各种各样的选择; nusoap,http://php.net/manual/en/book.soap.php,zend框架也有SOAP客户端和服务器,你可以使用它。无论您使用什么实现,都可以以某种方式获取数据。对任何保留初始响应的内容执行var_dump()应该可以帮助您浏览它。

如果您更喜欢使用DOMDocument class from php。您无需了解Xpath即可实现此功能。一个例子:
$url = "http://www.google.com";
$xml = new DOMDocument();
$xml->load("http://validator.w3.org/check?uri=".urlencode($url)."&output=soap12");
$doctype = $xml->getElementsByTagNameNS('http://www.w3.org/2005/10/markup-validator', 'doctype')->item(0)->nodeValue;
$valid = $xml->getElementsByTagNameNS('http://www.w3.org/2005/10/markup-validator', 'validity')->item(0)->nodeValue;
$errorcount = $xml->getElementsByTagNameNS('http://www.w3.org/2005/10/markup-validator', 'errorcount')->item(0)->nodeValue;
$warningcount = $xml->getElementsByTagNameNS('http://www.w3.org/2005/10/markup-validator', 'warningcount')->item(0)->nodeValue;
$errors = $xml->getElementsByTagNameNS('http://www.w3.org/2005/10/markup-validator', 'error');
foreach ($errors as $error) {
echo "<br>line: ".$error->childNodes->item(1)->nodeValue;
echo "<br>col: ".$error->childNodes->item(3)->nodeValue;
echo "<br>message: ".$error->childNodes->item(5)->nodeValue;
}
// item()参数不均匀,因为标记之间的空文本被计为项目。
