RE : Help me to eliminate the reduce/shift confliction

[Johnny_xia]

This grammar has no conflictions. But it can't work. Consider such a xml file.
<xml>
<information>
<test value=10003/>
<collections>
<collection>
     <colnum value=10001/>
     <colvalue value="aaa"/>
</collection>
</collections>
</information>
</xml>

when test element is reduced, bison tries to read a token sxmlETag, it tries to
shift by
rule sxmlElement:sxmlSTag sxmlElement sxmlETag.
