"DTMLMethod" and "DTMLDocument" have a method "document_src"
that return their source (as text/plain). You can let
your browser save this as a local file, edit it and later
upload it again.
Attached is a patch that exposes this method as a tab.

The properties for the source list looks like... /test_dtml /test_dtml/document_src ... the property tagged by dst is the link to the unrendered source. What I really need to do is extract this from the properties rather than simply appending /document_src onto the end of everything. As you point out (partially) document_src has no meaning in the context of some objects and also other WebDAV servers may use a different syntax than simply adding /document_src on the end of the URL. At least this works for Zope. For my next trick ;^) I am going to try to make it general, as you suggest and add a "Get Source" menu option so that the user has some choice over getting the rendered or unrendered source. Also, I am working on adding an "Edit" option which does a "get source" into a temp file then fires up the user's editor of choice and a thread to monitor the modification time of the temp file. Each time the file changes it gets put back into Zope. That way the user can use the "Save" command on the editor. (By the way I E-mailed the authors of DAVExplorer to get their input. waiting for a reply.) Anyway I'm having fun and getting somewhere at last!!

Thanks to the info from Martijn Pieters this turned out to be trivial.
The unrendered source for a DTML method is reached by appending
/document_src to the end of the URL. For example,
http://localhost:8080/mystuff becomes
http://localhost:8080/mystuff/document_src .
In the context of DAVExplorer the solution is to modify the GET so that
the /document_src is appended correctly. Not that this can't be done too
early since the URL is used for other internal book keeping. I found
that the folowing modification works
In dav_explorer/classes/DAVExplorer/WebDAVManager.java make the
following change at line number 119 ...
try {
Response = Con.Generic(MethodName, ResourceName, Body,
Headers);
WebDAVResponseEvent webdavResponse =
GenerateWebDAVResponse(Response,tn);
fireResponse(webdavResponse);
}
... becomes ...
try {
if (MethodName.equals("GET")) {
Response = Con.Generic(MethodName, ResourceName +
"/document_src", Body, Headers);
} else {
Response = Con.Generic(MethodName, ResourceName, Body,
Headers);
}
WebDAVResponseEvent webdavResponse =
GenerateWebDAVResponse(Response,tn);
fireResponse(webdavResponse);
}
... note you don't need to change PUT since PUT does the right thing.
I've tested this out quickly and it seems to do what I want.
The sources to DAVExplorer can be found via a link at www.webdav.org to
http://www.ics.uci.edu/~webdav/ enjoy!

[EMAIL PROTECTED] Yes I already have load_site but it is (as far as I can see) an upload tool. I can't edit anything that has already been uploaded so I have to keep a local copy of everything. What can happen is that someone else updates a page from their local copy then I update from mine and lose the changes. The idea with WebDAV was that I could lock edit and unlock with the only copy being in the Zope database. -- Graham --- Beware of Geeks bearing GIFS. http://www.jlab.org/coda Jefferson lab DAQ group ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

With the info you have given me I can probably modify the sources to DAVExplorer so that it gets the source rather than the rendered document. I had thought that maybe I was missing something in my Zope config. Perhaps it would have been better if I had, less work ;^) I have been using a very nice HTML editor under Linux, called Quanta+, unfortunately it can't open anything except local files. That's fine when I'm at work since I can use ZOPEEdit (ftp) or LocalFS. (LocalFS doesn't behave well with trees and other navigation products so I try to avoid it). The problem is that from home I can't use ftp becaues of the firewall. I've tried to tunnel through ssh but that doesn't work for me. I've been looking at WebDAV or writing something using ZClient but my python is very rusty. If anyone has any comments or a solution to my problem, editing DTML through a firewall using something other than netscape, please let me know.

This is because according to the WebDAV spec, documents are retrieved using a plain 'GET' command, which is exactly the same as what browsers do. However, the spec also provides for a way to find out where to get the source of the document found at a specific URL, via the so-called Source Link. Zope provides this link, but I have yet to find a client that'll honour it and give you easy access to it. The relevant sections in the WebDAV spec are: http://andrew2.andrew.cmu.edu/rfc/rfc2518.html#sec-5.4 and http://andrew2.andrew.cmu.edu/rfc/rfc2518.html#sec-13.1 Now, I haven't seen either WebDAV client, if they support this feature, please let us know! -- Martijn Pieters | Software Engineermailto:[EMAIL PROTECTED] | Digital Creations http://www.digicool.com/ | Creators of Zope http://www.zope.org/ | The Open Source Web Application Server - ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
