Method from org.apache.cocoon.generation.MP3DirectoryGenerator Detail:
protected void setNodeAttributes(File path) throws SAXException { super.setNodeAttributes(path); if (path.isDirectory()) { return; } RandomAccessFile in = null; try { in = new RandomAccessFile(path, "r"); setID3HeaderAttributes(in); setID3TagAttributes(in); } catch (IOException e) { getLogger().debug("Could not set attributes for " + path, e); } finally { if(in != null) try{ in.close(); }catch(IOException ignored){} } } Extends the `setNodeAttributes` method from the `DirectoryGenerator` by adding MP3 tag attributes if the path is a MP3 file with valid tag.
