Set xml `string` tag value to that of another

Question

Is there a way to set the value of an xml string tag value to include that of another string tag value. The idea is like this:

<string name="tag1">"this is"</string>
<string name="tag2"><tag1 + " what I mean"</string>

Is this possible and if so how do I do it?

String concatenation is not yet supported in android string resource files, but doing it in java code is fairly easy. Check this SO thread for a similar question. — Clement Osei Tano, Aug 12 '17 at 23:05
no, this is not possible. Source was [here](https://stackoverflow.com/questions/10411699/concatenate-multiple-strings-in-xml) — Jeffason1997, Aug 12 '17 at 23:16

Arithmetic, concatenation operations are not possible in android resource files.

You can concatenate strings without writing any Java/Kotlin code, only XML by using this small library I created which does so at buildtime: https://github.com/LikeTheSalad/android-stem

Usage

Based on your example, you'd have to set your strings like this:

<string name="tag1">this is</string>
<string name="tag2">${tag1} what I mean</string>

And then after building your project, you'll get:

<!-- Auto generated during compilation -->
<string name="tag2">this is what I mean</string>

Set xml `string` tag value to that of another
