[OSM-dev] issue with geofabrik europe update

[Julien Fastré]

Hi,

We had a strange issue with a europe diff update from geofabrik: the
diff file is not a valid xml.

The affected file:

http://download.geofabrik.de/europe-updates/000/001/872.osc.gz

We encounter an error when parsing this file with osmosis:


```
org.openstreetmap.osmosis.core.OsmosisRuntimeException: Unable to parse
xml file 872.osc.  publicId=(null), systemId=(null), lineNumber=972870,

```

This come from the line 972870, which is not a valid xml tag indeed:

> <tag k="source:boundary" v="http://ka.wikipedia.org/w/index.php?title=%E1%83%A4%E1%83%90%E1%83%98%E1%83%9A%E1%83%98:Tbilisi_Admin_Map.jpg&fileuid="0" user="" changeset="0" timestamp=20080104164655"/>

Removing this line (`sed '972870d' 872.osc > 872.fixed.osc`) make
osmosis able to parse the file.

I wonder if we were the only one affected and, if not, how did you cope
to pass this diff without error ?

Thanks,
Julien
