Regular Expression matches multiple line example – Java
Below is the block that I'm trying to extract from the config file:. There are multiple ones just like this, each with a different MAC address. How do I match a config block across multiple lines? The first problem you may run into is that in order to match across multiple lines, you need to process the file's contents as a single string rather than by individual line.
For example, if you use Get-Content to read the contents of the file then by default it will give you an array of strings - one element for each line.
To match across lines you want the file in a single string and hope the file isn't too huge.
You can do this like so:. Use the Select-String cmdlet to do the search because you can specify -AllMatches and it will output all matches whereas the -match operator stops after the first match. Makes sense because it is a Boolean operator that just needs to determine if there is a match.
In case this may still be of value to someone and depending on the actual requirement, the regex in Keith's answer doesn't need to be that complicated. If the user simply wants to output each block the following will suffice:. Groups contains the whole matched string, Groups will contain the string match within the parentheses in the regex.
This regex will search for the text ap followed by any number of characters and new lines ending with a! So I was a little bored. I wrote a script that will break up the text file as you described as long as it only contains the lines you displayed. It might work with other random lines, as long as they don't contain the key words: ap, profile, domain, hostname, or area.

The new line and return characters are hidden characters, so you can't tell if they are there just by looking at them. That way if everything is on one line it should still work. If there is not a new line or return character I'm not sure. In this matter you'd have two pattern matching tokens so you would require a conditional logic in your workflow to pick the one that contains data or combine them into a single field as one result will be blank using the token calculator.

Is there any way to get Visual Studio to perform a regex replace across multiple lines let the match cross line boundaries? I know there are many editors I can use for this, but it seems strange that this feature has been left out of Visual Studio.
Am I missing something? Use the replace in files dialog Ctrl - Shift - H and the single line option? Singleline means: each file is treated as single line, dot.
Downside: you must use Find All and replace all, or replace by hand. Find next does not work. For the non-modal dialog Ctrl - H and find next, use. Regular expressions have changed in Visual Studio See how the.
