Question

我觉得我做的事情真的不对。在做肥皂时，他们给我带了一个xml，可能包含也可能没有错误。如果没有读取值，我想检查错误是否存在。不知何故，我无法直接抓住它:(

下面是一些带结果的示例返回，另一个给出错误（找不到名称）

<?xml version="1.0" encoding="utf-8"?>

            </searchPersonResult>
        </searchPersonResponse>

和没有结果的那个

<?xml version="1.0" encoding="utf-8"?>
<soapEnvelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/08/addressing" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">

            <wsuExpires>2011-05-27T12:16:45Z</wsuExpires>
        </wsuTimestamp>
    </envHeader>
    <soapBody>
        <searchPersonResponse xmlns="http://www.rechtspraak.nl/namespaces/ccr01">
            <searchPersonResult>
                <CCR_WS xmlns="http://www.rechtspraak.nl/namespaces/ccr">
                    <exceptie errorcode="1">No Results found.</exceptie>
                </CCR_WS>
            </searchPersonResult>
        </searchPersonResponse>
    </soapBody>
</soapEnvelope>

这是我选择命名空间的代码，然后检查

$results = simplexml_load_string($response);
$results->registerXPathNamespace('ccr','http://www.rechtspraak.nl/namespaces/ccr');

$lijst = $results->xpath('//ccr:CCR_WS');
$errorcode  = $lijst[0]->exceptie->attributes()->errorcode;
$error      = $lijst[0]->exceptie;
if (isset($errorcode) AND $errorcode != "") {
    // do things with the error code
} else {
    $lijst = $results->xpath('//ccr01:searchPersonResult'); 
    $cur = $lijst[0]->CCR_WS->curandus;
    echo $cur->ccn."<BR>";
    echo $cur->cur_voornamen."<BR>";
    echo $cur->cur_voorvoegsels."<BR>";
    echo $cur->cur_achternaam."<BR>";
    echo $cur->geboorte_datum."<BR>";
    echo $cur->geboorte_plaats."<BR>";
}

肯定有更好的抓取方法 $ lijst [0] - ＆GT; exceptie-＆GT;属性（） - ＆GT;错误代码

例如......

Answer 1

...不知道这对每个人来说是否是“更好的方法”，但这里有一个直接的XPath表达式来选择错误代码。通过删除步骤并使用//（在开头或中间），可以缩短效率并降低效率。如果您更喜欢较长的语法，则使用@（或使用attribute::轴选择属性。如果attribute（或exceptie元素）不存在，则不返回任何内容。

/*/*/ccr01:searchPersonResponse/ccr01:searchPersonResult/ccr:CCR_WS/ccr:exceptie/@errorcode

请记住注册您在XPath表达式中使用的所有名称空间前缀。
