</div>TXMLConfig is a simple wrapper to store name/value pairs in xml.<br>
You can access the full XML via cfg.Doc.<br>

<br>

<br>
</div>You can store lists, trees, graphs as name/value pairs.<br>

<br>
</div>If you only use TXMLConfig and not the Doc then it can do the same as<br>
a TIniFile. Of course there are speed and size differences.<br>

</div>TXMlConfig uses a pretty complete XML parser/writer.<br></blockquote></div><br></div><div class="gmail_extra">Thanks to all the advice, I managed to make it work. I will add my example to the wiki in order to make this clear to other users as ignorant as I am :-)<br clear="all">
