dom4j 读取 XML 文件“特殊字符”问题，困扰很久, 请帮忙

mackcyl 2010-07-21 02:34:35

test.xml，内容如下

<?xml version="1.0" encoding="gbk"?>
<DOCUMENT>
<item>
<display>
<pbid>77</pbid>
<introduction> 这里的特殊字符 ®</introduction>
</display>
</item>
</DOCUMENT>

使用dom4j 读取时，报如下 Exception ;

Nested exception:

请问如何在不人工手动改变test.xml文件的情况下，通过 dom4j 解析 test.xml文件中的“ ® " 等特殊字符？谢谢大家 ~~
