这是原字符串，我想取出其中的xml那段字符串，要肿么来写那个正则，自己写的总是为空，整不出来。

结果应该为：
<?xml version="1.0" encoding="UTF-8" ?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:ns1="http://www.liveipc.com/UserService/">
<SOAP-ENV:Body>
<ns1:UserOperationResponse>
<WSResponse>
<Version>1.0</Version>
<CharSet>GBK</CharSet>
<TransactionName>UserLogin</TransactionName>
<Random>244ab25cf7f0258401c2ae0b038ead0a</Random>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

关键是后面的ius不区分大小写多行匹配模式
