I am going through a large website (1600+ pages) to make it pass Priority 1 W3C WAI.  As a result, things like image tags need to have alt attributes.

What would be the regular expression for finding img tags without alt attributes?  If possible, with a wee explanation so I can use to find other issues.

I am in an office with Visual Web Developer 2008.  The Edit >> Find dialogue can use regular expressions.


Question: How do I set serial special characters?
Answer: NewLine is not what you are looking for. It's the plain old 'new line' sequence, e.g. CR LF or LF alone.

The special characters are handled like this:


EOF — set to 0x1a, you cannot change it in .NET
ERR — set by SerialPort.ParityReplace
BRK — don't know
EVT — set to 0x1a, you cannot change it in .NET
XON — set to 0x11, you cannot change it in .NET, and it doesn't even usually make sesn
XOFF — set to 0x13, you cannot change it in .NET, and it doesn't even usually make sesn


It may be helpful for you to study the Win32 DCB structure as well. It's used by .NET internally to set the state of the serial port.
