Delete Blank Rows & Rows Below Meeting Condition

I have an imported report in a spreadsheet. It imports to three columns. I need to check each row in column A for three seperate criteria and delete the rows I don't need. I need to delete blank rows and check next row for page header info. Delete these and next rows to next blank cell. Check next row for page header and not delete if not page header. Several rows down will be a cell with 23 blank spaces before the word Reg: and sometimes other words past this but always this first. This row is to be kept. I looked at the FAQ's example of Deleting but I don't think it will work. I also need to put a key word in column A at a point where I want to stop. This report is a couple thousand rows long so a VBA procedure would really save time. I have a procedure I use to check for two zero's in two cells that hide these rows but I couldn't modify it to work on this report.
