Importing geometries from invalid GML

Question

I have the following gml geometry :

I'd like to import it as easily and fast as possible into QGIS.

• I've tried direct GML import => not a valid GML (and i quite agree with that ;))
• I can use QuickWKT => But then I need to put commas every two coordinates
• I've tried "Add delimited Text Layer" => But it does seem to work mainly for CSV file with coordinates on each line.

Do you have any ideas?

Answer 1

If you need commas every two coordinates for QuickWKT you can use a simple regular expression to create them.

Find: ([0-9\.]+ [0-9\.]+)

Replace: \1, (or $1, depending on the syntax).

So you end up with this:

  <gml:exterior>
    <gml:LinearRing>
