关于simplexml无法加载CDATA中数据的问题
<?php
$xmlstr = <<<EOF
<?xml version="1.0" encoding="UTF-8"?>
<MusicFeeds>
<Songs Action="Add">
<Name type="Native"><![CDATA[不装饰]]></Name>
<Artist><![CDATA[王菲]]></Artist>
<PRODUCTID>jwadyqjsge3dccbogr</PRODUCTID>
</Songs>
<Songs Action="Add">
<Name type="Native"><![CDATA[又继续等]]></Name>
<Artist><![CDATA[王菲]]></Artist>
<PRODUCTID>jwadyqjsge3dccboge</PRODUCTID>
</Songs>
<Songs Action="Add">
<Name type="Native"><![CDATA[只有你]]></Name>
<Artist><![CDATA[王菲]]></Artist>
<PRODUCTID>jwadyqjsge3dccbogc</PRODUCTID>
</Songs>
</MusicFeeds>
EOF;
$xml = simplexml_load_string($xmlstr);
var_dump($xml);
?>
xml文件的节点中如果含有CDATA，用simplexml_load_string或simplexml_load_file函数读取里面的数据是读取不出来的(不管是中文还是字母或字符)，我自己亲自测试过了。
SimpleXMLElement Object
(
[Songs] => Array
(
[0] => SimpleXMLElement Object
(
[@attributes] => Array
(
[Action] => Add
)
[Name] => SimpleXMLElement Object
(
[@attributes] => Array
(
[type] => Native
)
)
[Artist] => SimpleXMLElement Object
(
)
[PRODUCTID] => jwadyqjsge3dccbogr
)
[1] => SimpleXMLElement Object
(
[@attributes] => Array
(
[Action] => Add
)
[Name] => SimpleXMLElement Object
(
[@attributes] => Array
(
[type] => Native
)
)
[Artist] => SimpleXMLElement Object
(
)
[PRODUCTID] => jwadyqjsge3dccboge
)
[2] => SimpleXMLElement Object
(
[@attributes] => Array
(
[Action] => Add
)
[Name] => SimpleXMLElement Object
(
[@attributes] => Array
(
[type] => Native
)
)
[Artist] => SimpleXMLElement Object
(
)
[PRODUCTID] => jwadyqjsge3dccbogc
)
)
)
如果将代码改为
<?php
$xmlstr = uncdata($xmlstr);
$xml = simplexml_load_string($xmlstr);
var_dump($xml);
?>
则cdata里面的数据可以正常输出了。
