[osmosis-dev] osmosis --tag-transform not actually transforming

[Vivek Nallur]

Hi all,

I'm trying to modify an OSM file using Osmosis, using the following
commandline:

> osmosis --read-xml ./dublin-m50.osm --tag-transform no_highway_transform.xml --write-xml dublin-m50-modified.osm

Unfortunately, no errors are reported and a new file is created. But when I 
open the file, the required tag hasn't been transformed :(

I created a simple transformation file like so:

=========
<translation>
        <name>Do not use highways</name>
        <description>Changes the value of the maxspeed key to be negative</description>
        <match mode="and" type="way">
                <tag k="highway" v="secondary"/>
                <tag k="maxspeed" match_id="speed" v=".*"/>
        </match>
        <output>
                <copy-all />
                <tag from_match="speed" v="-1" />
        </output>
</translation>

===========

I'm unable to diagnose what I'm doing wrong. I tried to write stats to a file, but 
all I get is the name of the transformation file inside it.

I'm using Osmosis Version 0.43.1, so I'm assuming the tag-transform plugin doesn't 
need to be built separately.

Any ideas/suggestions would be appreciated. 

Note: I'm aware that highways could be removed using "reject-ways highway=motorway,motorway_link"
but let's just assume that I actually want to update a tag's value.
