Question

我有SimpleXMLElement，我需要获取内容（内容= 10）我试过

 $xml   = simplexml_load_string($summContent);
 $array = json_decode(json_encode((array) $xml), 1);
 $array = array($xml->getName() => $array);

但是有xml - false和array - false

$summContent = {SimpleXMLElement} [6]
id = "https://spreadsheets.google.com/feeds/cells/1-fR7MXmjsr0juPWsbpK9RSY_WVW_XK77-krsmEcmdc4/oxi7ruj/private/full/R14C2"
updated = "2016-07-26T10:49:49.902Z"
category = {SimpleXMLElement} [1]
title = "B14"
content = "10"
link = {array} [2]

我尝试了$summContent->content

result = {SimpleXMLElement} [2]
@attributes = {array} [1]
0 = "10"

$xml   = simplexml_load_string($summContent);

异常：

Warning: simplexml_load_string(): Entity: line 1: parser error : Start tag expected, '&lt;' not found

如何转换为数组？

更新

我使用Spreadsheet google api，当我为summ创建字段时，我得到了这个summ，在我得到坐标后我得到了这个summ的xml但是无法得到这个字段，谁知道如何转换这个SimpleXMLElement

转储我的SimpleXMLElement：

‌‌$summContent
SimpleXMLElement::__set_state(array(
'id' => 'https://spreadsheets.google.com/feeds/cells/1-fR7MXmjsr0juPWsbpK9RSY_WVW_XK77-krsmEcmdc4/ood4aof/private/full/R14C2',
'updated' => '2016-07-26T11:30:46.528Z',
'category' => 
SimpleXMLElement::__set_state(array(
 '@attributes' => 
array (
  'scheme' => 'http://schemas.google.com/spreadsheets/2006',
  'term' => 'http://schemas.google.com/spreadsheets/2006#cell',
),
)),
'title' => 'B14',
'content' => '10',
'link' => 
array (
0 => 
SimpleXMLElement::__set_state(array(
   '@attributes' => 
  array (
    'rel' => 'self',
    'type' => 'application/atom+xml',
    'href' => 'https://spreadsheets.google.com/feeds/cells/1-fR7MXmjsr0juPWsbpK9RSY_WVW_XK77-krsmEcmdc4/ood4aof/private/full/R14C2',
  ),
)),
1 => 
SimpleXMLElement::__set_state(array(
   '@attributes' => 
  array (
    'rel' => 'edit',
    'type' => 'application/atom+xml',
    'href' => 'https://spreadsheets.google.com/feeds/cells/1-fR7MXmjsr0juPWsbpK9RSY_WVW_XK77-krsmEcmdc4/ood4aof/private/full/R14C2/lj40r',
  ),
)),
),
))

更新

我这样得到fiel content = 10：

$arraySummContent = (array) $summContent;
$content = $arraySummContent['content'];

但我想知道为什么：

$xml = simplexml_load_string($summContent);

SimpleXMLElement gete元素或转换为数组
