It certainly was very helpful to have the 'reverse talk' of me asking questions and the rest offering advice on XML issues. I had not ben aware that Grant had a prior involvment with XML::Simple. Notwithstanding The advice to avoid this, I went home and added a 'ForceArray' parameter with appropriate element names, and my short script did what I needed it to do. When run over the data that I had, it produced the 80,000+ records that I was wanting. It is only a 'one-off' use, so I am unlikely to migrate this specific one to XML::LibXML, but future excursions into other XML will follow that path. Thanks again for all the productive advice.<span class="HOEnZb"><font color="#888888"><br>

Hi Mongers<br>
<br>
Thanks to everyone who came along and contributed to the various debates<br>
and inquisitions last night - I thoroughly enjoyed the meeting.<br>
<br>
Notes for Peter:<br>
<br>
1. Don't use XML::Simple<br>
<br>
2. If you insist on ignoring '1', be sure to enable XML::Simple's<br>
"strict mode" as described here:<br>
<br>
<a href="http://www.perlmonks.org/index.pl?node_id=218480" rel="noreferrer" target="_blank">http://www.perlmonks.org/index.pl?node_id=218480</a><br>
<br>
This would have alerted you to the need to define ForceArray.<br>
<br>
3. Using XML::LibXML would give you fewer surprises. It is easily<br>
installed on Ubuntu/Debian with:<br>
<br>
apt-get install libxml-libxml-perl<br>
<br>
4. The XML::LibXML documentation is not great, but this article should<br>
help you convert code from XML::Simple to XML::LibXML:<br>
<br>

<br>
5. You might also want to look at an XPath tutorial, e.g.:<br>

<br>
<br>
The slides from my Postgres history triggers talk are up on the web site<br>
(complete with bugs) here:<br>
<br>
<a href="http://wellington.pm.org/archive" rel="noreferrer" target="_blank">http://wellington.pm.org/archive</a><br>
<br>
The final slide includes a link to resources.zip which includes all you<br>
need to set up the simple DB that I described, and try out the triggers.<br>
<br>
<br>
Thanks Richard for your interesting presentation (and also for<br>
requesting the other talk). I think you're going to have to come up<br>
with a name for your project and feel sure the group can come up with<br>
suggestions. Here's some to get the ball rolling:<br>
<br>
* credcheck<br>
* nbad (the "Nothing But Auth" daemon)<br>
* bbad (Bare Bones Authentication Daemon)<br>
* authify<br>
* ics (Isolated Credentials Store)<br>
* adwan (authentication daemon without a name)<br>
<br>
<br>
The next meeting will be on September the 8th - let me know if you'dlike<br>
to do a talk.<br>
<br>
Regards<br>
Grant<br>
