Help: how to change an "add" and how to delete

[lboening]

I have an app.config file. It has many "add" entries in the "appSettings" section.

Using your tool, it is easy to add a key with a particular value.

But how do I target a particular "add", such as the fourth one in the list?

Example:
<add key="MaxConcurrentAutoVueControls" value="3" />

If I add, I then have two keys, one with the proper setting. The fourth one on the list is still in the appSettings set with unchanged values.

Is it possible to delete a particular key with your tool?

I know how to do it using other techniques.

Maybe a bit late to the party here but you can address individual nodes by using the key or another attribute on the node. Use the following syntax:

{ 
"configuration/appInfo/add[@key='SomeKey']/@value": "SomeValue",
"configuration/appInfo/add[@key='AnotherKey']/@value": "$(SomeBuildOrReleaseVariable)",
"configuration/appInfo/add[@key='MaxConcurrentAutoVueControls']/@value": 3,
}

To delete you could always <clear /> and then <add />

@lboening Could you please explain a bit detailed this case:

If I add, I then have two keys, one with the proper setting

It would be useful to have piece of you config file as well as your transformations.
If you have duplication of MaxConcurrentAutoVueControls key, it won't be correct behavior and should be treated as a bug.

Also, as @markjose mentioned before, you can address specific key by add[@key=...] syntax.

Another part of you request is deleting nodes. Because of this, I mark it as new feature request and will try to take a look what I can do here.

[sergeyzwezdin]

I've added syntax to remove nodes.
In upcoming 1.3.0 version it will be possible to do something like this:

{
  "#configuration/appInfo/add[@key='SomeKey']/@value": ""
}

Please note, that # at the start of transformation key means that node will be deleted.

Latest fixes were released to Nuget and VS Marketplace.

Hey @sergeyzwezdin how do I add the "clear" tag mentioned by you above?
I tried adding "configuration/connectionStrings/clear": "" but it created a <clear></clear> tag which is incorrect.
Thanks
