Question with XSLT: pass parameters to JSP
Subject: Question with XSLT: pass parameters to JSP
From: "Ping Chen" <cecho77@xxxxxxxxxxx>

My questions is that when I use <xsl:for-each select="DataSource"> to get
@name of EACH DataSource, how could I pass this value as a parameter to a
JSP page? Like in the following "users-attr.xsl". Because every time, it
just return me "//DataSource[1]/@name", How could I get
"//DataSource[i]/@name"(i=1..n) and pass EACH {@name} to the JSP page?
Another question, when I try to pass two <xsl:variable> to a JSP page as
parameters, I met a question with the second parameter:
<a href="nextstep.jsp?p1={$param1}&p2={$param2}">next step</a>
Could anyone please tell me how should I do to get them?
Thanks in advance!
