Processing XML file inside a zip file

Processing XML file inside a zip file

[Aditya Mahajan]

Hi,

Is it possible to process an XML file inside a zip file without unzipping?

In particular, I have a program that generates zip files which look like 
this:

The file `filename.zip` contains:
- filename.xml 
- file_hash1.png
- file_hash2.png
etc.

Where `filename.xml` (the name matches the basename of the zip file) is 
the main xml file and the `file_hash1.png` etc are png files that are 
referred to inside the xml file.

If I unzip the file and add

\setupexternalfigures[directory={path-to-unzipped-folder]

then, I have an \startxmlsetups .. \stopxmlsetups environment that 
correctly typesets the xml file. I believe that I have seen Hans post 
snippets of code that suggest that context can directly read from a zip 
file. So, I am wondering if there is a way that I can just call

context --magic-flags filename.zip

and obtain the correct output.

Thanks,
Aditya

You can directly typeset ePub files which is just zipped XML.  There is
a script in mtxrun for it:

    context --ctx=x-epub.ctx yourfile.epub

Thanks. But I could not find `x-epub.ctx` file in the standalone 
distribution.
