Routinely (24 times per day = 1 get per hour) parse section of HTML page (i.e.: specific table) to output.txt. I need syntax/regex to parse specific section, NOT all source code.

Hello, I need to parse a specific web page's table (I'm using PowerShell/WMI ($wc.downloadstring) to download source code) and output to output.txt. If I pull the entire source code, I get duplicate events/data for obvious reasons - which then throws off my numbers of events (based on repeats) I need to pull the exact section of the page 24 times a day (1 x per hour), and output to file. What I need: The regex syntax to search html source code - specific section/table. Should I use a named variable to identify the code for beginning of the table and the end of the table - which means I can output or index all the content within? Thanks in advance for your help!
