using regex to replace a string

[AlecSadler]

Hello all I am still working on my instant messenger project and I have came across a nasty bug.

When too many messages are placed in a conversation it slows my program way down, so I'm trying to trim old messages off the conversation text.

I am trying to do this with regular expressions, however I'm having no luck so far.

Here is what I'm trying (want to replace everything except "Some text to keep" with a blank string ""

$msg = "<div style='float: left;width: 90%;border: 3px solid #11AAFF;padding: 10px;text-align:left;margin-bottom:10px;' > STORM: Hello World<br/></div><div style='float: left;margin-top:-8px;margin-bottom:5px;width:100%;font-size: 8px;'>2017-16-07 21:08:21</div>"
$msg &= "Some text to keep"
$msg = StringRegExpReplace($msg, '<div([^%]*?)<br\/><\/div><div([^%]*?)<\/div>', "", 1)
ConsoleWrite($msg&@CRLF)

I got it figured out.

Am using the following pattern "(?i)<div(.*?)</div>(.*?)</div>"

Simpler:

$msg = "<div style='float: left;width: 90%;border: 3px solid #11AAFF;padding: 10px;text-align:left;margin-bottom:10px;' > STORM: Hello World<br/></div><div style='float: left;margin-top:-8px;margin-bottom:5px;width:100%;font-size: 8px;'>2017-16-07 21:08:21</div>"
$msg &= "Some text to keep"
$msg = StringRegExpReplace($msg, '.*</div>', "")
ConsoleWrite($msg&@CRLF)
