is it possible to download a zip file containing just one xml file and then use it in iVIewer?

[Tulio]

I have a 33MBytes XML file to load into iViewer and process it to show in a list (channel guide).

The problem is the xml file is large, daily updated, and I was wondering if it is possible to download as zip file (only 2MB) and then somehow manipulate inside iViewer.

I saw a phrase in GitHub that makes me dream: "This takes advantage of iViewer's ability to load zip files, and use any file in the zip as if it was a local file to the GUI." (Embedded HTML Demo)

thanks

I tested with a xml file in a zip, i can see that IViewer get the file, but i dont know how i can get the .xml inside the .zip to parse.

If this work, get the .zip files and use files like .js and xml, i will be a happy guy today. Very useful.

I tested using CF.request, but maybe will work if i try with CF.loadAsset, but i just dont know how to get the file from a different URL then the .gui, because the file will be in a different place. CF Team ? 

If work, i have serious plans to use it.

Thanks

I have uploaded a demo project to github which loads zip files via CF.request, extracts the files within the zip, then inflates (unzips) them, then uses the raw data to create JS objects you can work with.
Works for XML and JSON data.

In the example, its loading the ZIP files from the same path as the .GUI file, but you can easily change that to load the zip file from any web server.

thanks thanks thanks, you made two guys very happy :-)

I will let Clayton test and post results, as he is the JS guy :-)

[Clayton Vicente]

Tulio is drinking much coffee this days, JS guy only for Jarrod, Barry, Florent...i am a beginner yet :)

Jarrod you made the code very simple to understand, very thanks. I will test tomorrow, but i am reading the code already.

Hi

Download the zip and unzip to get the xml works fine, but unfortunately its more fast to download a .xml with 3.6mb then a .zip with 488kb

I am posting a little test here, its just a little modification in the Jarrod´s example.

We can test downloading the .zip file from Dropbox and Mediafire, the .xml is in Dropbox.

Just for curiosity, why its more fast download the big .xml file ?

The attachment was just the XML data, were you meaning to attach a guiDesigner project?

I am not sure why you would experience a faster download of a much larger file - but perhaps it's cached somewhere for your request somehow?

I am sleeping yet, sorry.

Well, you can see in the test, i really don't know why Jarrod, maybe you can help me to understand this better.

Two other people test this too, in different cities, same result. Get the big .xml its more fast.

OK so its not the download time that your script is testing, but the entire time including unzipping, etc - this might take some time as the unzipping is being handled in JavaScript, not native code. Would also depend on your compression level, etc.

Yesterday this was my first thought too, but unzip the file its very fast, milliseconds.

I modify the script to get the time just after the request, before the unzip action, same thing.
