[xsl] interpreting WML 1.3 content w/XSLT

---

---

All --

I'm trying to transform some wml 1.3 content into HTML, but I'm having a
problem with interpreting forms and variable resolution.

Most WML forms I have seen use markup like the following:

    <p>
       Symbol:
      <br/>
      <input name="v36" value=""/>
      <a title="Submit"
href="http://ye.yahoo.com/http://finance.yahoo.com/q?s=$(v36:escape)">
Submit</a>
      &nbsp; 
    </p>

Here, we see that the input field's name is 'v36', and the data from this
field in placed into the URL by the WML browser by variable substitution
( $ precedes a WML variable reference) when the user 'submits' the form
(by executing the hyperlink). This is a case I think I can handle, but
gets complicated by the fact that WML doesn't have an enclosing form
element.

This is the problem that I run into:

  <card title="Search">
    <onevent type="onenterforward">
      <refresh>
        <setvar name="U" value="/exec/obidos/ct/text/vnd.wap.wml/-/"/>
        <setvar name="T" value="tg/aa/wml/uk/"/>
        <setvar name="S" value="subst/aa/wml/uk/"/>
      </refresh>
    </onevent>
    <do name="ok" type="accept" label="OK">
      <go
href="$(U)$(T)searchall/-/blended/$(item:escape)/1/202-6049706-5439020"/>
    </do>
    <p mode="wrap" align="left">
       Please enter search word(s): 
      <br/>
      <input name="item"/>
      <a
href="$(U)$(T)searchall/-/blended/$(item:escape)/1/202-6049706-5439020">Go</a>
    </p>
  </card>

Here I am up a big creek, because the variables are defined in one scope
and referenced in another! I can't use xsl:variable, because if I try to
create a variable of global scope (i.e. not in a template), I can only
assign it once, and if I create a template to read in and assign all of
the setvar elemets, they will be out of scope when I process the next
element.

I'm afraid that I'll have to do this w/DOM or SAX parsing...

Any ideas?

Thanks,

Craig
