PHP SimpleXML函数的xpath问题
在centOS上装了apache 跟php
运行以下php文件
<?php
$xml = simplexml_load_string("<note> <to> George </to> <from> <dt>John</dt> </from> <heading> Reminder </heading> <body type=\"small\" important=\"low\" > Don't forget the meeting! </body> <mm/>ddddddd </note>");
print("1 !!!!\n");
print_r( $xml->xpath('body'));
print("2 !!!!!!!!!!!\n");
print_r( $xml->xpath('/note'));
print("3 !!!!!\n");
print_r( $xml->xpath('/note/to'));
print("4 !!!!!!!!!!!\n");
print_r( $xml->xpath('/note/from'));
?>
输出
[root@AY1212020301569343979 controllers]# php tt.php
Cannot load Zend Extension Manager - it was built with configuration 1.2.0, whereas running engine is API220100525,NTS
1 !!!!
Array
(
[0] => SimpleXMLElement Object
(
[@attributes] => Array
(
[type] => small
[important] => low
)
)
)
2 !!!!!!!!!!!
Array
(
[0] => SimpleXMLElement Object
(
[to] => George
[from] => SimpleXMLElement Object
(
[dt] => John
)
[heading] => Reminder
[body] => Don't forget the meeting!
[mm] => SimpleXMLElement Object
(
)
)
)3 !!!!!
Array
(
[0] => SimpleXMLElement Object
(
)
)
4 !!!!!!!!!!!
Array
(
[0] => SimpleXMLElement Object
(
[dt] => John
)
)
感觉所有结果都跟网上示例不同
比如根据网上的教程，第三个输出应该类似于
本来用到xpath的页面都是正常的，后来在服务器上用yum装了php-devel跟gcc，也不知道是不是装了这两个东西的缘故，所有用到xpath的地方返回的值都变成空的了
求教，到底哪儿出问题了
