remove-invisible-elements removes <clipPath> with <g>

[JoKalliauer]

Processing File:Oxygen15.04.1-application-x-bzip.svg with

svgcleaner input.svg output.svg --indent 1

accoring to Validators: Error: SVG element g not allowed as child of SVG element clipPath in this context. (Suppressing further errors from this subtree.) or with DTD: document type does not allow element "g" here

so the problem is:

 <clipPath id="ai">
  <g transform="matrix(.8051 0 0 .8051 12.58 14.2)">
   <path d="m23.156 54.281c-.554-.002-1.08.0166-1.5625.0313-2.57.0782-4.06.375-4.0625.375v68.594c.141.68.751 1.19 1.4688 1.1875l55 .0313c.0531 0 .998-.008 1.6875 0 10.1-4 25.4-22.5 34.344-31.469 1.48-1.66 1.13-1.14 1.4688-2.875v-35.469c-.174-.0174-29.5-2.92-49.062 16.656-14.8-14.8-31-17-39.281-17.062z" fill="#cebfa5" opacity=".4"/>
  </g>
 </clipPath>

But librsvg and inksape render it still correctly.

I would keep such elements, but as I said the file is invalid, therefore you might want to close this issue.

This is a correct behavior. clipPath does not support g children. They have no effect. It's a known Inkscape bug (not sure for librsvg).

svgo using collapseGroups can repair such files with:

svgo -i input.svg.txt -o output.svg.txt --disable=removeUnknownsAndDefaults --enable=collapseGroups --disable=convertPathData
