I'm using the replace module of Ansible (http://docs.ansible.com/ansible/replace_module.html).
My file is:
...
net route-domain /Common/0 {
id 0
vlans {
/thisrow/AAAA_yyyyy
/Common/http-tunnel
/Common/socks-tunnel
/Common/BIGIP-HA
/thisrow/AAAA_xxxxx
}
}
...
I need to remove all rows containing /thisrow/ inside vlans.
I'm using this regex: (^ vlans )(?P<vlanrow>){([^}]*)}{0}.*vasgk.*\n but I don't know how to remove ALL thisrow from vlanrow group
Thanks,
Riccardo
This is not a dupl. Ansible is not the problem. The problem is the regular expression matching just 1 time thisrow. Try it on https://regex101.com/r/n3rRsl/1
I've came up with the following playbook, using a little modified regexp of yours and the sample data from regex101 you provided.
playbook.yml
- hosts: localhost
tasks:
- replace:
dest: /home/user/config.conf
regexp: '(^ vlans )(?P<vlanrow>){([^}]*)}{0}(\s{8}/vasgk.*)\n'
replace: '\1\2{\3'
register: result
until: result.changed == False
retries: 4094 # you can't have more vlans!
This is the result:
net route-domain /Common/0 {
id 0
vlans {
/Common/http-tunnel
/Common/socks-tunnel
/Common/BIGIP-HA
}
}
It seems to be quite slow though, but should give you an idea. Hope that helps!
Edit:
changed
(^ vlans )(?P<vlanrow>){([^}]*)}{0}(.*/vasgk.*)\n
to (^ vlans )(?P<vlanrow>){([^}]*)}{0}(\s{8}/vasgk.*)\n, this fixed problems with spacing.
I need to extract a username from the log below via regex for a log collector.
Due to the nature of the logs we're getting its not possible to define exactly how many forward slashes are going to be available and I need to select a specific piece of data, as there are multiple occurances of similar formatted data.
Required data:
name="performedby" label="Performed By" value="blah.com/blah/blah blah/blah/**USERNAME**"|
<46>Jun 23 10:38:49 10.51.200.76 25113 LOGbinder EX|3.1|success|2016-06-23T10:38:49.0000000-05:00|Add-MailboxPermission Exchange cmdlet issued|name="occurred" label="Occurred" value="6/23/2016 10:38:49 AM"|name="cmdlet" label="Cmdlet" value="Add-MailboxPermission"|name="performedby" label="Performed By" value="blah.com/blah/blah blah/blah/USERNAME"|name="succeeded" label="Succeeded" value="Yes"|name="error" label="Error" value="None"|name="originatingserver label="Originating Server" value="black"|name="objectmodified" label="Object Modified" value="blah/blah/USERNAME"|name="parameters" label="Parameters" value="Name: Identity, Value: [blah]Name: User, Value: [blah/blah]Name AccessRights, Value: [FullAccess]Name: InheritanceType, Value: [All]"|name="properties" label="Modified Properties" value="n/a"|name="additionalinfo" label="Additional Information"
I've tried a few different regex commands but I'm not able to extract the necessary information without exactly stating how many / there will be.
blah\.com[.*\/](.*?)"\|name
Try this :
blah\.com.*\/(.*?)"\|
Check here
If your username format is this :
value="abc.xyz/something/something/..../USERNAME"
then use this :
\..*\/(.*?)"
check here
Possible solution:
value="[a-z\.\/]*\/(.*)"
(The first capture group is the username)
Working example:
https://regex101.com/r/qZ0zC8/2
Mayby like this?
blah.(\w+\/)+\K([\w]+)
It's catch Username but since it's between ** so I also match them

I'm new in regex and I'm trying to only display this on a site using regex:
"joyLikelihood": "VERY_LIKELY",
"sorrowLikelihood": "VERY_UNLIKELY",
"angerLikelihood": "VERY_UNLIKELY",

How do you think should I go about it? since the "very_likely" or "VERY_UNLIKELY" results depending on the image.
Good evening Stackoverflow,
I am stuck in a spot where I can't get Scala regex matches to play nice, here is my code
private def handle_read(packet: TFTPReadRequestPacket, tftp_io: TFTP): Unit = {
val MAC_REGEX = "([0-9A-F]{2}[:-]){5}([0-9A-F]{2})".r
packet.getFilename match {
case MAC_REGEX(a) => println(s"Client is coming from $a")
}
}
When the regex is ([0-9A-F]{2}[:-]) and I request for the file 70-it is fine and spits out that the client is "coming from 70", but when it is the full regex and I request 70-CD-60-74-24-9C it throws an exception like such
[ERROR] [04/28/2015 21:25:27.818] [polydeploy-baremetal-akka.actor.default-dispatcher-4] [akka://polydeploy-baremetal/user/TFTP_Queue] 70-CD-60-74-24-9C (of class java.lang.String)

What I am wanting to try and accumplish is to be able to have a TFTP request come in for pxelinux.cfg/01-70-CD-60-74-24-9C and pull out the MAC address.
Any and all help is greatly appreciated!
Thanks, Liam.
When the regex is ([0-9A-F]{2}[:-]) and I request for the file 70- it is fine
This is because, in this case, your regex contains a single group.
This worked for me:
val MAC_REGEX = "(([0-9A-F]{2}[:-]){5}([0-9A-F]{2}))".r
"70-CD-60-74-24-9C" match {
case MAC_REGEX(a, _*) => println(s"Client is coming from $a")
}
// prints "Client is coming from 70-CD-60-74-24-9C"
It works because I wrapped the entire regex with a group. a captures that outer group and _* is a sequence of ignored matches for all the other groups. Apparently Regex's extractor returns a list with an element for each capture group.
I have a feeling there is a better way to do this though...
Does someone have a regular expression that gets a link to a Youtube video (not embedded object) from (almost) all the possible ways of linking to Youtube?
I think this is a pretty common problem and I'm sure there are a lot of ways to link that.
A starting point would be:
http://www.youtube.com/watch?v=iwGFalTRHDA
http://www.youtube.com/watch?v=iwGFalTRHDA&feature=related
http://youtu.be/iwGFalTRHDA
http://youtu.be/n17B_uFF4cA
http://www.youtube.com/embed/watch?feature=player_embedded&v=r5nB9u4jjy4
http://www.youtube.com/watch?v=t-ZRX8984sc
http://youtu.be/t-ZRX8984sc
... please add more possible links and/or regular expressions to detect them.
So far I got this Regular expression working for the examples I posted, and it gets the ID on the first group:
http(?:s?):\/\/(?:www\.)?youtu(?:be\.com\/watch\?v=|\.be\/)([\w\-\_]*)(&(amp;)?[\w\?=]*)?
You can use this expression below.
(?:https?:\/\/)?(?:www\.)?youtu\.?be(?:\.com)?\/?.*(?:watch|embed)?(?:.*v=|v\/|\/)([\w\-_]+)\&?
I'm using it, and it cover the most used URLs.
I'll keep updating it on This Gist.
You can test it on this tool.
I like #brunodles's solution the most but you can still match non video links like https://www.youtube.com/feed/subscriptions
I went with this solution
(?:https?:\/\/)?(?:www\.)?youtu(?:\.be\/|be.com\/\S*(?:watch|embed)(?:(?:(?=\/[-a-zA-Z0-9_]{11,}(?!\S))\/)|(?:\S*v=|v\/)))([-a-zA-Z0-9_]{11,})
It can also be used to match multiple whitespace separated links.
The video id will be captured in the first group.
Tested with the following urls:
youtu.be/iwGFalTRHDA
youtube.com/watch?v=iwGFalTRHDA
www.youtube.com/watch?v=iwGFalTRHDA
http://www.youtube.com/watch?v=iwGFalTRHDA

I improved the links posted above with a friend for a script I wrote for IRC to recognize even links without http at all. It worked on all stress tests I got so far, including garbled text with barely recognizable youtube urls, so here it is:
~(?:https?://)?(?:www\.)?youtu(?:be\.com/watch\?(?:.*?&(?:amp;)?)?v=|\.be/)([\w\-]+)(?:&(?:amp;)?[\w\?=]*)?~
I testet all the regular expressions that are shown here and none could cover all url types that my client was using.
I built this pretty much through trial and error, but it seems to work with all the patterns that Poppy Deejay posted.
"(?:.+?)?(?:\/v\/|watch\/|\?v=|\&v=|youtu\.be\/|\/v=|^youtu\.be\/)([a-zA-Z0-9_-]{11})+"
Maybe it helps someone who is in a similar situation that I had today ;)
Piggy backing on Fanmade, this covers the below links including the url encoded version of attribution_links:
(?:.+?)?(?:\/v\/|watch\/|\?v=|\&v=|youtu\.be\/|\/v=|^youtu\.be\/|watch\%3Fv\%3D)([a-zA-Z0-9_-]{11})+

I've been having problems lately with the atttribution_link urls so i tried making my own regex that works for those too.
Here is my regex string:
(https?://)?(www\\.)?(yotu\\.be/|youtube\\.com/)?((.+/)?(watch(\\?v=|.+&v=))?(v=)?)([\\w_-]{11})(&.+)?
and here are some test cases i've tried:

Also remember to check the string you get for your video url, sometimes it may get the percent characters. If so just do this
url = [url stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
and it should fix it.
Remember also that the index of the youtube key is now index 9.
NSRange youtubeKey = [result rangeAtIndex:9]; //the youtube key
NSString * strKey = [url substringWithRange:youtubeKey] ;
It'd be the longest RegEx in the world if you managed to cover all link formats, but here's one to get you started which will cover the first couple of link formats:
http://(www\.)?youtube\.com/watch\?.*v=([a-zA-Z0-9]+).*
The second group will match the video ID if you need to get that out.
(?:http?s?:\/\/)?(?:www.)?(?:m.)?(?:music.)?youtu(?:\.?be)(?:\.com)?(?:(?:\w*.?:\/\/)?\w*.?\w*-?.?\w*\/(?:embed|e|v|watch|.*\/)?\??(?:feature=\w*\.?\w*)?&?(?:v=)?\/?)([\w\d_-]{11})(?:\S+)?

Detects YouTube and YouTube Music link in any string
I took all variants from here:
https://gist.github.com/rodrigoborgesdeoliveira/987683cfbfcc8d800192da1e73adc486#file-youtubeurlformats-txt
And built this regexp (YouTube ID is in group 2):
(\/|%3D|v=|vi=)([0-9A-z-_]{11})[%#?&\s]
Check it here: https://regexr.com/4u4ud
Edit: Works for any single string w/o breaks.
I'm working with that kind of links:
http://www.youtube.com/v/M-faNJWc9T0?fs=1&rel=0
And here's the regEx I'm using to get ID from it:
"(.+?)(\/v/)([a-zA-Z0-9_-]{11})+"
This is iterating on the existing answers and handles edge cases better. (for example http://thisisnotyoutu.be/thing)
/(?:https?:\/\/|www\.|m\.|^)youtu(?:be\.com\/watch\?(?:.*?&(?:amp;)?)?v=|\.be\/)([\w\-]+)(?:&(?:amp;)?[\w\?=]*)?/
here is the complete solution for getting youtube video id for java or android, i didn't found any link which doesn't work with this function
public static String getValidYoutubeVideoId(String youtubeUrl)
{
if(youtubeUrl == null || youtubeUrl.trim().contentEquals(""))
{
return "";
}
youtubeUrl = youtubeUrl.trim();
String validYoutubeVideoId = "";
String regexPattern = "^(?:https?:\\/\\/)?(?:[0-9A-Z-]+\\.)?(?:youtu\\.be\\/|youtube\\.com\\S*[^\\w\\-\\s])([\\w\\-]{11})(?=[^\\w\\-]|$)(?![?=&+%\\w]*(?:['\"][^<>]*>|<\\/a>))[?=&+%\\w]*";
Pattern regexCompiled = Pattern.compile(regexPattern, Pattern.CASE_INSENSITIVE);
Matcher regexMatcher = regexCompiled.matcher(youtubeUrl);
if(regexMatcher.find())
{
try
{
validYoutubeVideoId = regexMatcher.group(1);
}
catch(Exception ex)
{
}
}
return validYoutubeVideoId;
}
This is my answer to use in Scala. This is useful to extract 11 digits from Youtube's URL.
"https?://(?:[0-9a-zA-Z-]+.)?(?:www.youtube.com/|youtu.be\S*[^\w-\s])([\w -]{11})(?=[^\w-]|$)(?![?=&+%\w](?:[\'"][^<>]>|))[?=&+%\w-]*"
def getVideoLinkWR: UserDefinedFunction = udf(f = (videoLink: String) => {
val youtubeRgx = """https?://(?:[0-9a-zA-Z-]+\.)?(?:youtu\.be/|youtube\.com\S*[^\w\-\s])([\w \-]{11})(?=[^\w\-]|$)(?![?=&+%\w]*(?:[\'"][^<>]*>|</a>))[?=&+%\w-./]*""".r
videoLink match {
case youtubeRgx(a) => s"$a".toString
case _ => videoLink.toString
}
}

function clean_youtube_link($link)
{

}
}
This should work for almost all youtube links when extracting from a string:
((?:https?:)?\/\/)?((?:www|m)\.)?((?:youtube\.com|youtu.be))(\/(?:[\w\-]+\?v=|embed\/|v\/)?)([\w\-]{10}).\b
var isValidYoutubeLink: Bool{
