From an XSL file, what is the best way to process a cookie?

    By clicking a link on a website I set a USERINFO cookie and then I
    redirect to a program which ultimately executes an XSL file which
    dynamically builds an input form. The input form, while having some non

    dynamic hidden INPUT tags, has one hidden INPUT tag that is dynamic. In

    the XSL file I attempt to bring this dynamic hidden INPUT tag in via
    the following statements:

    <xsl:template match="/">
    <xsl:value-of select="document('http://localhost/getcookie.jsp')"/>


    Unfortunately, the XSLT processor produces the following errors:

    obhtmlpage.cpp:146: Error: Exception rethrown in
    obdgxtxsl.cpp:213: Error: ObDgxtTransform
    obdgxtxsl.cpp:153: Error: ObCallDgxtTransform
    obdgxtxsl.cpp:32: Error: 0: syntax error at line 1, col 49: syntax
    obdgxtxsl.cpp:32: Error: 0: xpl_document: error parsing

    Below is the getcookie.jsp. I thought I was being straight forward with

    this. But I'm confused as to what the processor is talking about; the
    XSL above or the JSP below? What does it mean line 1 column 49? Any and

    all help is appreciated, thanks.

    P.S. - I know I removed " + cookievalue + " below in lieu of the non
    dynamic which you see, but even that failed. :-( I also tried
    xsl:copy-to and import with this fixed code, but to no avail. Again,
    any and all help is appreciated.

    <%@ page import="javax.servlet.http.Cookie"

    Cookie info = null;
    Cookie[] cookies = request.getCookies();
    for (int i=0; i < cookies.length; i++) {
    info = cookies;
    String cookiename = info.getName();
    String cookievalue = info.getValue();
    if (cookiename.equals("USERINFO")) {
    <input type="hidden" name="varuserinfo" id="varuserinfo"
    <% }

    I'm not really fluent in XML/XSL/XSLT but need to come up with a way
    of removing
    a set of radio buttons on an XSL produced form. I thought, good, I'll
    set a cookie and somehow use that value in the value clause of a hidden
    HTML INPUT tag. Hence the so
    called "dynamically" generated HTML tag which I tought would be
    considered well formed because I gave it an ending INPUT tag.

    I also thought initially that maybe I could just have a javascript
    extract the cookie value via an ONLOAD statement in a BODY tag, but
    then I couldn't figure out the XSL like syntax I would need to make use

    of this javascript variable. So more poking around on the internet led
    me to the XSL:value-of statement below and copy-of and import
    statements with the document parameter and I thought, okay, this looks
    promising. But no such luck.

    This is what I had tried the Javascript way which also doesn't seem to
    The XSL file has:

    <xsl:stylesheet version="1.0"


    <script language="JavaScript" xml:space="preserve"


    <xsl:variable name="cookie"

    (The transformer barfs on the above, but loves everything else about
    the XSl file if I comment out the above).


    <xsl:if test="@cookie = 'uservalue'">
    <input type="hidden" name="userinfo" id="userinfo" value="uservalue"/>


    and the javascript which returns the cookie looks like this:

    function getUserInfo() {
    var arrayofcookies = document.cookie.split(";");

    var i = 0;
    var userinfo = "USERINFO";
    var nocookie = 1; // Set for later
    while (i<arrayofcookies.length)

    //Split the current cookie into name=pairs.
    //Index 0 should be the name, and Index 1
    //should be the value.

    var cookiename = arrayofcookies.split("=")[0];
    var cookievalue = arrayofcookies.split("=")[1];

    if (cookiename == userinfo)
    nocookie = 0;
    // userrole.setAttribute("select",""+cookievalue+"");
    i = i + 1;


    Any and all help is appreciated.

    Did you define the cookie: namespace for that extension function
    invocation? Correctly?
