title: xml to svg dynamically
body: <p>I have been searching for months now about this subject, but I can't find anything about it. What I'm looking for: I have sheetmusic on my screen, which is xml converted to svg  with javascript. Now I want to make buttons with which I can manipulate the SVG that's displayed on the screen. For example: the music has lyrics underneath the notes and chords above it. Let's say I want to replace or remove them with an onclick button. All this temporarily, only on the screen.</p>
