dtd小错误，大虾求助啊,在线等
大虾求助一个小问题，下面的dtd哪里出问题了
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<!DOCTYPE introduction [
<!ELEMENT introduction (intro)>
<!ELEMENT intro (member pname mode analysis)>
<!ELEMENT member (id name sex resp note)>
<!ELEMENT pname (#PCDATA)>
<!ELEMENT mode (#PCDATA)>
<!ELEMENT analysis (#PCDATA)>
<!ELEMENT id (#PCDATA)>
<!ELEMENT name (#PCDATA)>
<!ELEMENT sex (#PCDATA)>
<!ELEMENT resp (#PCDATA)>
<!ELEMENT note (#PCDATA)>
]>
<?xml-stylesheet type="text/xsl" href="homework.xsl"?>
<introduction>
<intro>
<member>
<id/>
<name/>
<sex/>
<resp/>
<note/>
</member>
<pname/>
<mode/>
<analysis/>
</intro>
</introduction>

[解决办法]
元素用逗号分割
