Question

Update XML File with Ajax or JavaScript

Asked by: jayrod

I need to be able to write / update an XML file with Ajax or JavaScript.  I have seen solutions that update a node or something, but do not physically write to the specified XML file.  I am using ASP.Net 2.0, but my host will not allow the updating / writing of XML Files via ASp.Net due to their security policy.  

We think updating the file via client-side Ajax or JavaScript DOM will get us around this, but cannot find any good solutions / example.  Any help is greatly appreciated!!

You can update the "structure" of the XML file on the clientside, but it will the changes are only visible on the client. If you want to retain the changes, your server-side must allow you to write the changes to the file. Othewise as soon as the person leaves the page, the changes will be lost.

We are trying to write to the server.  From everything i see it looks like it cannot be done, correct?  Thanks!

>>From everything i see it looks like it cannot be done, correct?
Correct, but that answer is based on this "...but my host will not allow the updating / writing of XML Files via ASp.Net due to their security policy"
Of course, my assumption is that you want to save the updated xml file to the filesystem of your server. If your host offers databases, you could create a database to hold/save your xml contents. Hence, instead of saving the updated xml to the filesystem, you would save it to the database.
In terms of the applications that will use your xml data, it makes no difference if your xml is served from a database or from the filesystem. All that matters is that your XML file must be well formed.
Hence, instead of retrieving: http://somesite.com/myFile.xml you could write some script that will query the database and retrieve the data. For example: http://somesite.com/getData.asp?id=3
Then in getData.asp, you would need to query the database to retrieve the XML content with id=3.
