Remember that Apache OpenOffice regular expressions divide up the text to be searched - each paragraph in Writer is examined separately.įor example: ^red matches 'red' at the start of a paragraph ( red night shepherd's delight).įor example: red$ matches 'red' at the end of a paragraph (he felt himself go red)įor example: ^red$ matches inside a table cell that contains just 'red' The dollar '$' special character means 'match at the end of the text'. The circumflex '^' special character means 'match at the beginning of the text'. changed? finds change and changed - the d is optional because it is followed by a question mark.seprate finds separate and seperate - means either an a or an e.sep.rate finds sep then any character then rate - eg separate, seperate, and indeed sepXrate.Enter them in the 'Search for' box, and make sure that regular expressions are selected. If you don't want to find out exactly how regular expressions work, but just want to get a job done, you might find these common examples useful. The least you need to know about regular expressions We'll continue to use the Find and Replace dialog to explain in more detail. That may not be very useful, but it shows the principle.

If you type xxx into the Replace with box, and click the Replace All button, these become ' xxx', 'hot xxx', 'b xxxe', 'you xxxog' In the Search box enter r.d - the dot here means 'any single character'.Ĭlicking the Find All button will now find all the places where an r is followed by another character followed by a d, for instance ' red' or 'hot rod' or 'b ride' or 'you r dog' (this last example is r followed by a space followed by d - the space is a character). On the dialog, choose More Options and tick the Regular Expressions box In Writer, bring up the Find and Replace dialog from the Edit menu. If you have little or no experience of regular expressions, you may find it easiest to study them in Writer rather than say Calc. You should check the status of the regular expression option each time you bring up the dialog, as it defaults to 'off'. The dialogs that appear when you use the above commands generally have an option to use regular expressions (which is off by default).
#REGULAR EXPRESSION NOT TO INCLUDE MANUAL#
Not all regex are the same - so reading the relevant manual is sensible. Regular expressions are very common in some areas of computing, and are often known as regex or regexp. We describe the use of Apache OpenOffice regular expressions aiming to be clear enough for the novice, while detailing the aspects that can cause confusion to more experienced users.Ī typical use for regular expressions is in finding text in a Writer document for instance to locate all occurrences of man or woman in your document, you could search using a regular expression which would find both words. Regular expressions can be both powerful and complex, and it is easy for inexperienced users to make mistakes. In simple terms, regular expressions are a clever way to find & replace text (similar to 'wildcards'). 17 Troubleshooting Apache OpenOffice regular expressions.16 The 'Replace with' box \t \n & $1 $2.13 Grouping (.) and backreferences \x $x.5 How regular expressions are applied in Apache OpenOffice.4 The least you need to know about regular expressions.2 Where regular expressions may be used in Apache OpenOffice.
