Hi, I recently needed to write some app logi usin <xsp:logic> tags. Into tags
we need to write some code like:
String myUserID = <xsp-session:getxml context="authentication"
path="/authentication/ID" as="string"/>;
Then, I updated <xsp-session:getxml> to serve strings.
Currently the attribute "as" of the element can have 3 values:
1-as="object" (default) returns a org.w3c.dom.DocumentFragment object. More
info at
http://xml.apache.org/xerces2-j/javadocs/api/org/w3c/dom/DocumentFragment.html
2-as="xml" return the DocumentFragment into <xsp-session:xml> tags.
3- return the value of the firstchild of the requested node. Example: If we
have:
<ID>MyID</ID>
<role>MyRole</role>
<data>
<fullname>TheFullName</fullname>
A) Then if we write:
<xsp-session:getxml context="authentication" path="/authentication/ID"
as="string"/>
will return "MyID"
B) <xsp-session:getxml context="authentication"
path="/authentication/data/fullname" as="string"/>
will return: "TheFullName"
Attached is the new session.xsl the place of this file is:
xml-cocoon2/src/java/org/apache/cocoon/components/language/markup/xsp/java
