dataset xml

[steve]

i've not used a dataset to write xml before. i'd like to know how i can use
dataset.writexml() to append to an existing xml file. secondly, i'd like to
know how i can load an xml file and delete records from it. i've seen the
dataset object can load xml pretty easily...but i haven't seen any examples
of deleting from one where the records are actually removed from the
original xml file.

the xml file is basically a transaction log. when the application starts, i
need to load the xml transaction file and drop records that are n days old.
when i submit transactions, i need to record what was sent and whether a
record was accepted/rejected.

any examples or links to them is greatly appreciated.

tia,

steve

Steve,

In my opinion is the dataset (or any XML file) not the right format to write
a log. AFAIK can you not append to that directly on disk.

you can append to it but writexml() doesn't put the <?xml /> header stuff in
the output stream...so you can't do a readxml().

as far as the format of the log...format follows function. ;^)
