XML/XSL


Hi Carsten,

We use XML/XSL in browser to generate some HTML data. XML and XSL
uses ISO-8859-1 encoding. In some cases HTML forms are generated,
the form data is submited with an URL-encoded get to the server.

We found that IE browsers encode the formdata in UTF8 before its
URL-encoded. Gecko browser just send ISO-8859-1.

Is there a way to enforce a certain encoding of submitted data?

This is an HTML question rather than an XSLT one, since it's about how
the browser behaves when it submits a form. You might try using the
accept-charset attribute on the <form> element to specify the
character encodings that you're willing to accept. Something like:

  <form action="filterform.htm" accept-charset="ISO-8859-1">
    ...
  </form>

Having said that, according to the HTML spec, browsers are supposed to
use the same character encoding when submitting a form as was used for
the HTML page itself. Perhaps IE is getting confused because you're
doing the transformation client-side or perhaps it just always submits
the form in UTF-8; it's hard to say without trying out the above.

In IE 5.5 at least, the default behavior is always to send URLs encoded as
UTF-8.  This can be changed in the Internet Options control panel, under the
"Advanced" tab, in the "Browsing" section.  I'm not sure if there is a way
to override this behavior programmatically; I did notice, however, that your
sample stylesheet lacked an explicit xsl:output element, which causes the
processor to default to XML output encoded as UTF-8.  You might try setting
the encoding of the HTML output explicitly in your stylesheet:

<xsl:output method="html" encoding="iso-8859-1"/>

cheers,
b.
