嵌套在数据中的Xml php属性

标签: php xml

我正在使用以下xml

<?xml version="1.0" encoding="UTF-8"?>
<ns2:worldmate-parsing-result xmlns:ns2="http://www.worldmate.com/schemas/worldmate-api-v1.xsd" request-id="100793160" received="2014-12-27T16:34:42.000Z">
    <status>SUCCESS</status>
    <error-msg>An itinerary confirmation e-mail was parsed successfully</error-msg>
    <headers>
        <header value="multipart/alternative;  boundary=&quot;Apple-Mail=_62E5BF7A-C482-4FE0-8F43-15613E46D5FD&quot;" name="Content-type" />
        <header value="&lt;xxxxx@me.com&gt;" name="Return-Path" />
        <header value="rule=notspam policy=default score=0 spamscore=0  suspectscore=3 phishscore=0 adultscore=0 bulkscore=0 classifier=spam adjust=0  reason=mlx scancount=1 engine=7.0.1-1412080000 definitions=main-1412270180" name="X-Proofpoint-Spam-Details" />
    </headers>
    <end-user-emails>
        <user email="yyyyy@me.com" />
    </end-user-emails>
    ....
 </ns2:worldmate-parsing-result>

我正在尝试访问xml中的以下数据:

xxxxx@me.com
yyyyy@me.com

我正在尝试使用以下代码访问第二个电子邮件地址。

$endus='end-user-emails';
$endUserEmails=$xml->$endus->attributes()->{'user'};
echo $endUserEmails;

不确定为什么,但它强迫我使用变量名,如果我使用破折号,我会收到错误。

您可以使用XML DOM Parser查询XML:

$doc = new DOMDocument;
$doc->Load('file.xml');
$xpath = new DOMXPath($doc);
$entries = $xpath->query('//end-user-emails/user/@email');
foreach ($entries as $entry) {
    echo $entry->nodeValue; //Or do something else with the email value
}

至关重要的是查询:

//end-user-emails/user/@email

这意味着:“对于标记<user>下的每个代码<end-user-emails>,都会返回email属性。”

对于第一封电子邮件,可以将其替换为:

//headers/header/@value

然后删除&lt;&gt;

示例:(使用php -a

$ php -a 启用交互模式

php > $doc = new DOMDocument();
php > $xmldoc = '<?xml version="1.0" encoding="UTF-8"?>
php ' <ns2:worldmate-parsing-result xmlns:ns2="http://www.worldmate.com/schemas/worldmate-api-v1.xsd" request-id="100793160" received="2014-12-27T16:34:42.000Z">
php '     <status>SUCCESS</status>
php '     <error-msg>An itinerary confirmation e-mail was parsed successfully</error-msg>
php '     <headers>
php '         <header value="multipart/alternative;  boundary=&quot;Apple-Mail=_62E5BF7A-C482-4FE0-8F43-15613E46D5FD&quot;" name="Content-type" />
php '         <header value="&lt;xxxxx@me.com&gt;" name="Return-Path" />
php '         <header value="rule=notspam policy=default score=0 spamscore=0  suspectscore=3 phishscore=0 adultscore=0 bulkscore=0 classifier=spam adjust=0  reason=mlx scancount=1 engine=7.0.1-1412080000 definitions=main-1412270180" name="X-Proofpoint-Spam-Details" />
php '     </headers>
php '     <end-user-emails>
php '         <user email="yyyyy@me.com" />
php '     </end-user-emails>
php '  </ns2:worldmate-parsing-result>';
php > $doc->loadXML($xmldoc);
php > $entries = $xpath->query('//end-user-emails/user/@email');
php > foreach ($entries as $entry) {
php { echo $entry->nodeValue."\n";
php { }
yyyyy@me.com

使用简单的xml(加载字符串或文件),您可以使用以下方式访问电子邮件:

$a = 'end-user-emails';
$xml = simplexml_load_string($str);

echo ($xml->$a->user->attributes()->email);

您需要指定值所在的标记,然后调用属性的名称
