Crazy Vim Stuff
Given a huge text file you want to extract some things from, here's how to delete all the lines that DON'T start with a regex in Vim:
then remove all the blank lines:
then sort it with:
:sort

:%s/^\(\(search text\)\@!.\)*$//g

:g/^$/ d

Value 'blah' is not facet-valid with respect to pattern 'meh'
I haven't done much with XSD, but I'm fixing an application that validates its (overly complex) xml config file against an XSD.
It reads in a database host address and validates it with a regex. I needed to add a port config entry so it looked simple enough. I just wanted to validate that the port is 1 to 5 digits and don't want to limit it to actual port ranges. It's just a simple validation to help catch typos. So I whipped up a regex "^\d{1,5}$".
Then I got the error "Value '3307' is not facet-valid with respect to pattern '^\d{1,5}$'". What does this mean? Well, I ran across this page which says "Particularly noteworthy is the complete absence of anchors like the caret and dollar." So I took out my caret and dollar and then the validation worked.

What this blog isn't
This blog isn't a place to put pictures of my kids.
This blog isn't a place for me to be a pundit.
This blog isn't a place for me to show off.
This blog isn't a place for innane product tie-ins, just to get google ad revenue.
It's just me, solving problems with Java and posting the particularly strange ones where the solution wasn't collected in a single place already.
Maybe it will evolve to more than that, but don't hold your breath.
