Remove node in SVG by id using xmlstarlet

I have a folder with many SVGs in them. From all SVGs, I need to remove a tag with a specific id. There are too many files to do this manually, so I worked on a shell script to do this for me, but cannot figure out how to use xmlstarlet to remove the tag.

For example, let's say we have foo.svg:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg version="1.1" xmlns="http://www.w3.org/2000/svg">
  <g id="delete"/>
  <g id="keep"/>
</svg>

      

        
        
        
      

    

Then the command is issued: xmlstarlet ed -d "g[@id='delete']" foo.svg > bar.svg

will result in the following:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg version="1.1" xmlns="http://www.w3.org/2000/svg">
  <g id="keep"/>
</svg>

      

        
        
        
      

    

but this is not the case. bar.foo still contains <g id="delete"/>

.

Does anyone know the correct command to remove a tag <g id="delete"/>

? Or any other tool I could use to batch precess the SVG files to get rid of the unwanted tag?
