Support osc file with multiple create/modify/delete tags

[HarelM]

I'm not sure this if this is already supported or not, but it would be great if this library would be able to support updating of a database using .osc files.

[HarelM]

Any updates on this?

[HarelM]

Seems like this library supports osmchange xml reading, but when using a file generated by osmupdate that has multiple create/modify/delete tags it reads only the last one.
Here's an example: israel-and-palestine-updates.osc.txt
I'll update the code and send a pull request.

@xivk I would be happy if you could merge this and create a new NuGet package.

I confused my self - the original issue was a question if osmupdate/osmconvert can be replaced by this library so it will run in-memory instead of in a different process.

[xivk]

This is now available in the latest prerelease packages.

You should be able to replace whatever osmupdate/osmconvert is doing. The only thing OsmSharp isn't very good at at the moment is writing OSM-PBF. It doesn't compress the files, like in the default format.

Thanks!
Will you be able to post some code to show how it's done? Meaning how do I take the changes from OsmChange and update the target stream or source or what-not...
Also the OsmUpdate downloads a lot of files and merges them in order to be able to update pbf file, I'm guessing this library doesn't have this code built in, right?

[xivk]

No the merging code isn't there, feel free to submit a new issue for that.

Once that is done updating a stream is almost trivial:

• Remove whatever is deleted.
• Add new stuff at the end.
• Update modifications.

But a sample or extension method to do that probably couldn't hurt either.
