[opencms-dev] Writing HTML directly into a vfs file

Mon Jun 30 22:19:02 CEST 2003

Matthias,

Thinking out loud here, but you should be able to do that by getting the
file as an instance of a CmsFile, using getContents to get a byte array,
and (now you have choices) using Xerces to deal with it as an XML file
(Well, XMLDocumentFragment, more likely) or manipulating it as a text
file. When you are done, you should be able to use CmsFile.setContents
to write back to the file.

So, it might look something like this:

public void writeHelloWorld(CmsFile file) throws CmsException {
  byte[] fileContents = file.getContents();
  /// ... do your thing here
  String helloWorld = "<![CDATA[ Hello World ]]>";
  file.setContents(helloWorld.getBytes());
  return;
}

Again, thinking off the top of my head, so this may be way
oversimplified.

As for finding files, there seem to be lots of ways of doing that. Look
at the javadoc for CmsObject for starters. (getFilesInDirectory is one
way)
