Using xxforms functions in Theme XSL file

Hi,
There is this new Orbeon Forms function, xxforms:get-request-header('User-Agent') that will return a user-agent string. How can I use this function within the Orbeon theme xsl file?

Anybody tried this before?

Thanks and regards.
Hoi Chong

Hoi,

The xxforms functions are available in XForms, that is, after the
page is loaded in the browser.

In the XSLT stage, you can use the Request Generator to get this
information into the xsl data or xsl variable.

Hank,
Thanks for the tip.

I have to modify the epilogue-servlet.xpl to get the user-agent request...

    <!-- Get request information -->
    <p:processor name="oxf:request">
        <p:input name="config">
            <config>
                <include>/request/container-type</include>
                <include>/request/request-path</include>
                <include>/request/headers/header[name =
'user-agent']</include>
                <include>/request/headers/header[name = 'accept']</include>
                <include>/request/parameters/parameter[starts-with(name,
'orbeon')]</include>
            </config>
        </p:input>
        <p:output name="data" id="request"/>
    </p:processor>

Then in my custom theme, I retrieve the user-agent value and assign to a
XSL variable.
After that I can check that variable and conditionally include in CSS or
JS files depending on the browser.

    <xsl:variable name="request" select="doc('input:request')"
as="document-node()"/>
    <xsl:variable name="current-user-agent"
select="$request/*/headers/header[name='user-agent']/value" as="xs:string"/>

                <xsl:if test="matches($current-user-agent,'MSIE 6.0')">
                  <xhtml:link rel="stylesheet"
href="/config/rbpf-theme/rbpf_ie6hc.css" type="text/css"/>
                </xsl:if>

Hope this is useful for others that are looking for ways to handle IE
peculiarities.

Regards.
