edit shared XML via asp.net page and save back to server.

Glenn M

I have a shared XML file on a server .

i also have one xslt file that performs a simple transform on in to
view the data.

now i want to have another page that lets users modify the shared xml
file via some editable controls such as text boxes , option boxes etc.

how can i implment this , should i use another xslt file with <INPUT>
controls . if so how can i save the result back using the asp.net
page.

or should i use asp.net to drive the whole page and not use an xslt
file . again , any pointers on how to do this would be useful.

thanks

I would stick with the ASP.NET approach. The DataGrid/DataSet has native XML support. You could populate the DataGrid with the XML file, allow users to edit the information inside of the DataGrid, and then save the XML file. OR -> You could create a custom object(s) that represent the XML file and serialize and deserialize the XML as necessary. In that form, you could continue to use text boxes, drop down lists, data grids, etc.

First, there is no reason to reinvent the wheel, if you are alredy using an
xslt transform and it does everything you need it to do, leave it alone. On
your edit page you could use an xmldocument object to write/save the data in
the xml document. When the user displays the "View" page the xlst will
reload the xml file and display the edited/updated information. Make sure
the authentication method you have chosen has write access to the xml file,
I used "everyone - write".

Here is a working sample
There are six files in this example, two webforms (View.aspx, Edit.aspx),
two code behinds, an xml document and an xlst file. Set View.aspx as the
startup page.

Hope this helps.

Thanks for that.

I have another question , i have a vbscript on server1 that parses an
xml file from my web server sever2 (http:\\server2 \myxml.xml)

The vbscript collects information from the server and amends the xml dom
object when a new record needs to be added or old one removed.

Now i want want to persist that xml back to the web server , and as we
know i can't save back directly. Any idea how i can work around this.

I was thinking of setting up a web sevice on the server or maybe feeding
the xml stream stream into an ASP.net page that would save it to the xml
file.

(alas the vbscript must reside on server1 and the xml file on sever2 )

any starting points to look at would be really useful.

Glenn,
Why can't you save the back to the web server? Do you mean it is
physically impossible; or you don't want to make security permission changes
to the virtual directory/file that needs to be updated? If you give write
access to the account the script runs against you shouldn't have a problem
modifying the script as long as you aren't trying to delete the file and
create a new one each time. You can use a web service as you suggested,
but, you will still have to account for security permissions which would
essentially do the same as modifying the DACL on the file itself. Is you
web server available to the public, or an Intranet server? Does your site
run under the IUSER account, Basic, or Windows auth? Can \\server1 access
\\server2 vice versa ? I have written web applications that will write xml
files to a different physical location, the only obstacle I have come across
is physical file security.

I would first try to modify the permissions on
\\server2\wwwro ot$\your_virtua l_directory\xml file.xml, make sure the user
account running the script can write to it. Modify your script to make the
necessary changes in the xml file via the XMLDOM object and you should be
good to go. If you want to replace \\server2\myxml .xml with the newly
generated copy from \\server1 then you will need to grant modify permissions
to the virtual directory where the file is stored and modify your script to
include:

set FSO = CreateObject("S cripting.FileSy stemObject")
Set MyXMLFile = FSO.GetFile("C: \MyXML.xml")
MyXMLFile.Copy ("\\Server2\www root$\your_virt ual_directory\M yXML.xml", True)
'True = Overwrite

Post your results, or any other details.
