Copying features with multiple attributes using QGIS

Question

For context, I am working on OSM road data, which are polylines. Some road segments belong to multiple roads because at some point they overlap then they become separate again. For an overlap segment, in the attribute, i will have both roads, for example "A10;A11" for highways 10 and 11, it can even contains 3+ roads each separated by a semicolon.

What i would like to do is some way of copying those segment for each road, for example, my feature with attribute "A10;A11" would become 2 features, one with the "A10" attribute, the other with the "A11" attribute. Obviously i want some kind of general command, i can do it by hand copying and editing features one by one but it would take forever and large data.

Would you know how to achieve that?

Answer 1

You can use the tool "Split features by character" from the toolbox.

Just chose your input layer, the attribute for the split and the character that defines the split. This produces a seperate feature for each value according to the defined split:
