使用 PHP 解析 Google Contacts API XML

Question

我有来自 Google Contacts API 的 xml feed，但在读取 标签时遇到问题。

$xml = simplexml_load_string($google_contacts);

这会读取除 标记之外的所有元素，其中包含电子邮件信息。

最好的做法是什么？

Answer 1

更新：如果您使用名称空间和 xpath，您可能需要注册它们首先在SimpleXML中。

如果您在访问某个元素时遇到问题，请尝试将其括在 {} 尖括号内，这可能会有所帮助：$xml->{gd:...}。

---

如果我没记错的话，SimpleXML 对 XML 命名空间没有/有限的支持。 DomDocument 有，所以用它代替。

对于第一次开始：

$dom = new DomDocument;
$dom->loadXML($google_contacts);
...

或者使用 DomDocument 来处理仅在 SimpleXML 中难以完成的部分：

$domElement = dom_import_simplexml($simpleXmlNode);

Answer 2

为了使其更易于使用，我所做的事情是通过将 alt=json 附加到请求字符串，将 gdata 返回为 json

我的完整查询字符串如下所示：

https://www.google.com/m8/feeds/contacts/{userEmail}/full?oauth_token=token&max-results=9999999&alt=json');

然后它只是常规 json。

Answer 3

您可以使用 xml_parse 读取“gd:”标签。它返回数组中的所有结果，因为 xml 字符串不由您共享，因此您需要编写进一步的逻辑来从数组中获取数据

<?php
$content = $google_contacts;
$parser = xml_parser_create();
xml_parse_into_struct($parser, $content, $data, $index);
xml_parser_free($parser);
print"<pre>";
print_r($data);
/*foreach($data as $vals )
{    
  //write your code to get result from array
}*/
?>

Answer 4

我遇到了同样的问题，无法访问 节点。
我制定了自己的解决方案，我需要每个条目下的完整联系人信息列表。
我猜这是因为每个 标记中存在冒号“:”，然后将其替换为无“:”，这就是我所做的：

$search=array('<gd:','</gd:');
$replace=array('<gd','</gd');
/*Create json object from $google_contacts(atom xml string)
by replacing "gd:" to "gd"*/
$response = json_encode(str_replace($search, $replace,$google_contacts));
/*Create Array from $response*/
$contactsList = json_decode($response, true);
print "<pre>" . print_r($contactsList['entry'], true);

这将使以下 Google Contact xml:

<? xml version = '1.0' encoding = 'UTF-8' ?>
<feed xmlns='http://www.w3.org/2005/Atom' xmlns:openSearch='http://a9.com/-/spec/opensearchrss/1.0/' xmlns:gContact='http://schemas.google.com/contact/2008' xmlns:batch='http://schemas.google.com/gdata/batch' xmlns:gd='http://schemas.google.com/g/2005'>

    ...

    </entry>
</feed>

到此 print_r数组的输出：
