[求助]这是怎么回事，应该怎么解决？
我用perl写的程序在日志文件中显示异常，请各位大虾帮帮忙！

显示不正常如下：


<?xml version = "1.0" encoding = "gb2312"?>
<log4j:event logger="triggerP"
timestamp="1143077034682"
level="INFO"
thread="21166">
<log4j:message><![CDATA[Receive Message Success!]]></log4j:message>
<log4j:NDC><![CDATA[undef]]></log4j:NDC>
</log4j:event>
<log4j:event logger="triggerP"

]]></log4j:message>
