Giacomo,
here's the sample:
1) The user goes to login.xml URI
2) A pipeline takes care of producing the proper HTML form
3) The user fills the form and activates "submit"
4) The "submit" event triggers a check-login.xml being requested
5) A pipeline takes care of calling SQLTransformer to check
login/password via a stored procedure.
6) The SQLTransformer emits an <sql:loginStatus> element which
contains the value of an output parameter of the stored
procedure, which may be "0" (login accepted), or "not 0" (login denied)
7) An XSL grabs the SQLTransformer's output and produces something like:
<control:status value="0" message="Login accepted"/> or
<control:status value="3" message="Wrong password"/>
8) I'd like to call another Transformer (let's call it
ControlTransformer) which scans the output of previous step and
sets a *sitemap parameter* called "status" to match the contents
of "value" attribute in <control:status> element
9) In the sitemap, using a ParameterSelector, the appropriate
map:redirect-to-uri is chosen, depending on the value of "status"
I know this may be done using XSP and/or actions, but I'd
like to stick to XML/XSL as much as I can, hence avoiding XSP and
actions, though I'm open to suggestions.
Regarding the use of the *sitemap parameter* term... I'm
confused, since in:
http://xml.apache.org/cocoon2/userdocs/selectors/selectors.html
The following sentence is reported: "ParameterSelector:
matches the string specified in the "test" parameter against a
specified Cocoon internal (e.g. sitemap) parameter;".
Hence, I supposed the term "sitemap parameter" was widely
used. I guess "session parameter" should be used instead, am I right ?
Thanks for your kind reply,
