Thanks, but

this tells you how to read a value
and no how to write a value

any other ideas?

To do that, you will have to parse the XML, make the modifications you need and re-create it, you can use the XMLBuilder library.

Probably thinking about it "a bit '", you could find a way to use a SQLite db in which to import / export XML.

Thanks again

know sqlite
but unfortunately I do not think it is feasible
because it is a file of a program already exists, I can only change the single value.

be sure to read the xml file as a string and use .Replace to change the value?

In theory my XOM library can open, modify and then save an XML document.

In practice i couldn't work out how the native java XOM library could do such a task - so was unable to know which java methods to include in my b4a XOM wrapper library.
I used the XMLBuilder library instead .

The java XOM tutorial can be found here: http://www.xom.nu/tutorial.xhtml.

@FabioG If you knew which java XOM methods and objects you need to use i could add them to the b4a XOM library.

Unfortunately, I do not know this

I'm trying with a simple Replace for Strings

@FabioG

Can you follow my b4a XOM example project (in the link above) and load your XML file?
Can you then parse some or all values - just iterate through some XOMElement objects and log their values?

If so we should be able to work out what to do next in order to modify XOMElement values and then save the modified XOMDocument.

It'd be more elegant to use XOM to do all three tasks: open, modify and save.

It'd probably be quicker to use either the XOM or b4a XmlSax library to open the XML document and read it's values into b4a objects - Maps and Lists etc - modify the values and then use the XMLBuilder to save the modified values to a new XML document.

Martin.
