Re: [Xsltforms-support] file uploads

[Tim T. <tim...@gm...>]

Hi, Conal,

I'm not sure about the support for different serialization formats, but I
did just test <xf:upload> with rev.638, and it worked for me (on Ubuntu):

<xf:upload incremental="true"
    mediatype="application/xml"
    ref="instance('file-upload')/upload/file">
    <xf:label>Select</xf:label>
    <xf:filename
        ref="instance('file-upload')/upload/file/@filename"/> <!-- Relative
XPath doesn't seem to work here. -->
</xf:upload>

When I upload a file, the file contents are inserted into the <file>
element in my "file-upload" instance, and I am able to POST the contents to
a server. When I do an upload, I get a relative file name (no file:///).

Hope this helps,
Tim
