问题描述
我目前想要获得的只是 gd:email 的属性，即address="，目前仅此而已.我可以进入 xml 部分，哎呀，只要它在标签内，我什至可以得到任何给定的想法，但要获得任何给定的属性，就像我的情况一样.我完全糊涂了.我曾经知道如何去做，但我已经很久没有做过任何对 XML 使用不简单的事情了.所以我把自己搞砸了..
What I am trying to get currently is just the attribute of gd:email that is the "address=" only nothing else as of the moment. Which I can get to the xml portion, heck I can even get any given think per say as long as its within tags like but to get the attribute of any given one like in my case.. I am completely confused on. I used to know how to do it but its been so long since I did anything that wasn't simple for XML useage. so I done messed my own self up..

代码看起来像(这是整个脚本(当前))
with code that looks like (this is the whole script (currently))
$user = "xxxxxxxxxxxxxxxxxxx@gmail.com";
$password = "xxxxxxxxxxxx";
// ref: http://code.google.com/apis/accounts/docs/AuthForInstalledApps.html
// step 1: login
$login_url = "https://www.google.com/accounts/ClientLogin";
$fields = array(
'Email' => $user,
'Passwd' => $password,
'service' => 'cp', // <== contact list service code
'source' => 'test-google-contact-grabber',
'accountType' => 'GOOGLE',
);
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL,$login_url);
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS,$fields);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($curl);
$returns = array();
foreach (explode("
",$result) as $line)
{
$line = trim($line);
if (!$line) continue;
list($k,$v) = explode("=",$line,2);
$returns[$k] = $v;
}
curl_close($curl);
// step 2: grab the contact list
$feed_url = "http://www.google.com/m8/feeds/contacts/$user/full?&max-results=5";
$header = array(
'Authorization: GoogleLogin auth=' . $returns['Auth'],
);
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $feed_url);
curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($curl);
curl_close($curl);
$doc = new DOMDocument();
$doc->load($result);
$arrFeeds = array();
foreach ($doc->getElementsByTagName('entry') as $node) {
$monkey = $node->getAttribute('{gd:email}');
$itemRSS = array($monkey->nodeValue);
array_push($arrFeeds, $itemRSS);
}
array_unique($arrFeeds);
推荐答案
看看DOMDocument 和 DOMXPath.为了获取属于特定命名空间一部分的节点，例如属于 gd 命名空间的 email 节点，您需要使用 注册命名空间DOMXPath 对象使用 DOMXPath::registerNamespace().命名空间 URI 通常位于 XML 文档的顶部.
Have a look at DOMDocument and DOMXPath. In order to get nodes that are part of a particular namespace, like the email node which is part of the gd namespace, you need to register the namespace with the DOMXPath object using DOMXPath::registerNamespace(). The namespace URI can usually be found at the top of the XML document.
示例:
$doc = new DOMDocument;
$doc->recover = true;
$doc->loadXML($result);
$xpath = new DOMXPath($doc);
$xpath->registerNamespace('gd', 'http://schemas.google.com/g/2005');
$emails = $xpath->query('//gd:email');
foreach ( $emails as $email )
{
echo $email->getAttribute('address');
// To get the title.
// This could also be done using XPath.
// You can also use ->nodeValue instead of ->textContent.
echo $email->parentNode->getElementsByTagName('title')->item(0)->textContent;
}
在上面的例子中，$result 是 $result = curl_exec($ch); 的结果.
In the example above, $result is the result of $result = curl_exec($ch);.
