Google使用PHP联系API XML解析

我有一个来自GoogleContactsAPI的xml提要，但是我在阅读更新时遇到了困难：如果您使用的是名称空间和xpath，那么可能是SimpleXML

如果您在访问元素时遇到问题，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名称空间没有/有限的支持。是的，所以拿着它吧

第一次开始：

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

或者仅对SimpleXML中难以完成的部分使用DomDocument：

$domElement = dom_import_simplexml($simpleXmlNode);

您可以使用xml_解析读取“gd:”标记。它返回数组中的所有结果，因为xml字符串不由您共享，所以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
}*/
?>

---

我遇到了同样的问题，无法访问

我做了一些事情，使它更容易使用，就是通过在请求字符串中添加
alt=json
将gdata作为json返回

我的完整查询字符串如下所示：

然后就是常规的json。
我会继续使用另一个XML解析器。将某些内容与当前的xml to object parser结合在一起可能最终会造成一些问题。取而代之的是DomDocument，它支持xml名称空间。请显示一些代码，尝试在其中访问这些元素。阅读不是特别的意思是什么？
<?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
}*/
?>

$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);

<? xml version = '1.0' encoding = 'UTF-8' ?>
