我尝试从php5.6迁移到php7.x但是我有读取xml的问题。
如果我在php5.6上运行此代码没有问题，在php7.x上有些奇怪的错误
echo 'LIBXML_VERSION ' . LIBXML_VERSION . "\n";
echo 'LIBXML_DOTTED_VERSION ' . LIBXML_DOTTED_VERSION . "\n";

我收到了这个输出和错误
LIBXML_VERSION 20904
LIBXML_DOTTED_VERSION 2.9.4
SimpleXMLElement对象 （ ）
警告：main（）：第122行的test4.php中不再存在节点
致命错误：未捕获错误：在test4.php中调用null上的成员函数children（）：122
在php5.6上我得到了
LIBXML_VERSION 20902
LIBXML_DOTTED_VERSION 2.9.2
SimpleXMLElement Object
(
[table-cell] => Array
(
[0] => SimpleXMLElement Object
(
[@attributes] => Array

)
[1] => SimpleXMLElement Object
(

[2] => SimpleXMLElement Object
(
[@attributes] => Array

这个修复如何在php7.x中运行？
