Tom,

 

Thanks for the suggestion.

 

Unfortunately, I forgot to mention in my original email that I had tried
that permutation as well . . . with out getting the desired effect =(

 

With the single quotes, the content-type gets paused through but still seems
to be getting ignored and I end up with an output file of the following
nature:

 

<!-- Output Snippet -->

<c:data xmlns:c="http://www.w3.org/ns/xproc-step"
name="1stFranklinFinancialCorp_CIK0000038723.txt"
content-type="text/plain">LS0tLS1CRUdJTiBQUklWQUNZLUVOSEFOQ0VEIE1FU1NBR0UtLS
0tLQ0KUHJvYy1UeXBlOiAyMDAx
LE1JQy1DTEVBUg0KT3JpZ2luYXRvci1OYW1lOiB3ZWJtYXN0ZXJAd3d3LnNlYy5nb3YNCk9yaWdp
. . . </c:data>

 

Dare I say this is a bug? If so, I suppose a work around would be to cast
back from base64 to string using an xPath function . . ?

 

Thoughts?

Christopher,

 

Try the following:

 

  <cx:unzip>

    .

    <p:with-option name="content-type" select="'text/plain'"/>

    .

  </cx:unzip>

 

(Single quotes around the text/plain value so that it is treated as a string
and not as an XPath expression)

 

That might help.

Hello,

 

I am trying to process some zipped text files in xproc (leveraging a
Calabash extension), but I am getting tripped up by base64 encoding.

 

My first draft of the xproc is below. Unfortunately, the content-type option
on cx:unzip seems to be getting ignored and I end up with an output file of
the following nature:

 

<!-- Output Snippet -->

<c:data xmlns:c="http://www.w3.org/ns/xproc-step" name="InputFile1.txt"
content-type="">LS0tLS1CRUdJTiBQUklWQUNZLUVOSEFOQ0VEIE1FU1NBR0UtLS0tLQ0KUHJv
Yy1UeXBlOiAyMDAx . . . </c:data>

 

I am I missing the obvious . . . or trying to do the impossible?

 

Most grateful for any feedback,

 

Christopher
