Hi,
I am trying to create an XML file, it will be done in stages so if the file
isn't present I will add the line:
<?xml version="1.0" ?>
<root_element>
Then for each line I add I add the following
<child_element>data<child_element>
But for various reasons the application won't know when the file is complete
so it won't have the final:
</root_element>
To solve this I intend to add the following each time
<child_element>data<child_element>
</root_element>
and delete the </root_element> every time I add a new
<child_element>data<child_element>. Can anyone tell me how I can delete the
last 15 characters from a file every time I open the file?
Thanks for your help
