Title: Question for updating existing XML file

Hi Andrew,

it can be easily done with XML documents stored in an XML database system. For example, try Sedna (http://www.modis.ispras.ru/Development/sedna.htm). Using Sedna you can do this by loading the XML document into database and then running statements in an update language. For example, to add another name Jane you should run the following statement:

UPDATE

insert <name>Jane</warning>

following //Entry/name[.="Jon"]

In general, the Sedna update language also allows you to manipulate XML data without rewriting the whole document.

Subject: [xml-dev] Question for updating existing XML file

Hi,

First time posting, new to the list.

How do you update your XML files? 
Example:
  (in a huge XML file...)
  <Entry>
   <name>Jon</name>
  </Entry>
  ...

If I want to update the name to Joe, or add another name Jane.  So the node looks like this:
  (in a huge XML file...)
  <Entry>
   <name>Joe</name>
   <name>Jane</name>
  </Entry>
  ...

Is there a way to do this kind of update without rewrite the whole file?  My file is about 50MB.

Thanks.
