我有一个我要解析的xml文件。第一部分有params是没问题的。但是从CDATA开始的第二个我无法弄清楚如何将其转换为数组。 我只需要json的分数部分。第一部分是params。我已经尝试过：
$xml = simplexml_load_string('<content>'.$xml.'</content>', null, LIBXML_NOCDATA);
和
$xml = simplexml_load_file('xmlfile.xml', 'SimpleXMLElement', LIBXML_NOCDATA);
我也试过修剪（$ xml），但我无法理解。你能帮助我吗？
XML文件：
<pujs>
<params>
<p id="p0" desc="mean temperature at 2m (°C)" name="t2m" pid="15" unit="°C" short_desc="mean T" type="4" precision="1"/>
<p id="p1" desc="precipitation accumulation (mm)" name="padavine" pid="26" unit="mm" short_desc="precipitation" type="4" precision="1"/>
<p id="p2" desc="mean wind speed (m/s)" name="veter_hitrost" pid="21" unit="m/s" short_desc="wind speed" type="4" precision="1"/>
<p id="p3" desc="mean global energy radiation (W/m2)" name="energija_gl" pid="27" unit="W/m2" short_desc="global energy" precision="0" type="4"/>
</params>

有没有人知道如何做到这一点并只获得json的一部分？或者所有转换为数组而不是我会这样做？请帮助我们，我有点迷失在这里......
答案 0 :(得分：0)
这很糟糕但很脏但是工作
<?php
$xml = file_get_contents('test.xml');
preg_match('@<!\[CDATA\[.+?\..+?\(\s*(.+?)\)\s*\]\]>@s', $xml, $cData);
$cData = preg_replace(array('@(\w+):@','@("HH":mm)@'),array('"\1":','HH:mm'),$cData[1]);
$json = json_decode($cData, true);
var_dump($json);
