Can't understand JVM instructions

Question

Could anybody help me to decompile the following code?
Seems to be a switch statement but I can't get real code out of these instructions.
I've stripped away some lines of unnecessary (as I think) code.
Most of all I am confused about this line :
if(!n.getNodeValue().equals("\n")) goto L6; else goto L5
What could it mean?
Those goto L6 and goto L5
Thanks in advance

_L3:
if(n.getNodeValue().equals(" "))
return "";
if(!n.getNodeValue().equals("\n")) goto L6; else goto L5
_L5:
doc.insertString(doc.getLength(), "\n\n", attrStyle);
return "\n\n";
_L6:
doc.insertString(doc.getLength(), n.getNodeValue() + " ", attrStyle);
return n.getNodeValue() + " ";
_L4:
doc.insertString(doc.getLength(), n.getNodeName(), attrStyle);
return n.getNodeName();
_L2:
if(n.getNodeName().equalsIgnoreCase("P"))
return s;
_L1:
return "";

I think the switch would look something like:
switch (n.getNodeType()) {
  case 1:
    if(n.getNodeValue().equals(" ")) return "";
  case 2:
    if(!n.getNodeValue().equals("\n")) {
      break
    } else // ???
  case 3:
    doc.insertString(doc.getLength(), "\n\n", attrStyle);
    return "\n\n";
  case 4:
    doc.insertString(doc.getLength(), n.getNodeValue() + " ", attrStyle);
    return n.getNodeValue() + " ";
  case 5:
    doc.insertString(doc.getLength(), n.getNodeName(), attrStyle);
    return n.getNodeName();
  default:
    if(n.getNodeName().equalsIgnoreCase("P")) {
}
