Need to get Particular word using java Regex

I want to get one particular word using regex in java. thanks
in the below paragraph, I need to find the network interface name
resource "azurerm_network_interface" "nic_LinuxVMCent-nhi" {
name = "nic_LinuxVMCent-nhi"
location = azurerm_resource_group.main.location
resource_group_name = azurerm_resource_group.main.name
ip_configuration {
name = "pubIP_LinuxVMCent-nhi"
subnet_id = azurerm_subnet.sub_wind12VM-PtN.id
private_ip_address_allocation = "Dynamic"
public_ip_address_id = azurerm_public_ip.pubIP_LinuxVMCent-nhi.id
}
}
data "azurerm_snapshot" "snapLinuxVMCent-nhi" {
name = "CentOS76New-0"
resource_group_name = "SaaSworkloadsnaps"
}
Expected Result Ex:
nic_LinuxVMCent-nhi

This is a multi-line bit of text. However, there appears to be a line which you could recognise with a regex:
resource "azurerm_network_interface" "nic_LinuxVMCent-nhi" {
So the regex for that would be ^resource "azurerm_network_interface" "([^"]+)" {$ - see https://regexr.com/67ldb
You can use Matcher.match to see if the any line matches this expression and if it does then matcher.group(1) will be the value you're looking for.

you can use this regex to find the network interface name:
(?<=resource \"azurerm_network_interface\" \").+(?=\" {)
I have used lookahead to find the name.
Also, here's a link to regex101:

I don't know network interfaces so,
This regex solution is specific to "azurerm_network_interface."
If you need any additional help, please comment down below.
Cheers :)

Removing Hashtag using Java WebFilter

I have the following configuration in the urlrewrite.xml:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 4.0//EN" "http://www.tuckey.org/res/dtds/urlrewrite4.0.dtd">
<urlrewrite use-query-string="true">
<rule>
<from>^(/event/showEventList)(\.{1})(\bhtm\b|\bhtml\b)(\?{0,1})([a-zA-Z0-9-_=&]{0,}+)(#{0,1})([a-zA-Z0-9-_=&]{0,}+)$</from>
<to type="redirect" last="true">/events$4$5</to>
</rule>
</urlrewrite>
The regex ^(/event/showEventList)(\.{1})(\bhtm\b|\bhtml\b)(\?{0,1})([a-zA-Z0-9-_=&]{0,}+)(#{0,1})([a-zA-Z0-9-_=&]{0,}+)$ has 7 groups, which are:
(/event/showEventList): matches /event/showEventList
(\.{1}): matches a single dot (.)
(\bhtm\b|\bhtml\b): matches only htm or html
(\?{0,1}): matches question mark (?) which can may occur zero or one
([a-zA-Z0-9-_=&]{0,}+): matches the query string which can occur zero or more
(#{0,1}): matches hashtag (#) which can may occur zero or one
([a-zA-Z0-9-_=&]{0,}+): matches the fragment which can occur zero or more
If I test this configuration with a test URL: /event/showEventList.html?pageNumber=1#key=val, I am expecting that the redirected URL would be /events?pageNumber=1, but I am getting /events?pageNumber=1#key=val
I have a code snippet to test it, which is:
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class UrlRewriterRegexTest {
public static void main(String[] args) {
String input = "/event/showEventList.html?pageNumber=1#key=val";
String regex = "^(/event/showEventList)(\\.{1})(\\bhtm\\b|\\bhtml\\b)(\\?{0,1})([a-zA-Z0-9-_=&]{0,}+)(#{0,1})([a-zA-Z0-9-_=&]{0,}+)$";
Pattern pattern = Pattern.compile(regex);
Matcher matcher = pattern.matcher(input);
System.out.println(matcher.replaceFirst("/events$4$5"));
}
}
It outputs to: /events?pageNumber=1.
Any pointer would be very helpful.

I'd simplify the expression a bit.
Escape slashes, as they are typically used as delimiters for the regex (\/event\/showEventList)
Remove superfluous quantifier (\.)
Shorten the html string test (htm(l)?) - careful, this messes with your capturing group numbers
Remove word boundary checks around html
Use ? instead of {0,1}
Use * instead of {0,}
Remove possessive quantifier (I don't see why you'd need it)
Ignore everything after #, you don't seem to need it in your replacement
This gives us ^(\/event\/showEventList)(\.)(htm(l)?)(\??)([a-zA-Z0-9-_=&]+)*#(.+)$ which subsitutes your example to /events?pageNumber=1
To play around, see https://regexr.com/4otp7

I've simplified the expression and here is the working solution
<from>^(\/event\/showEventList\.html?)(\?[a-zA-Z0-9-_=&]*)\#.*$</from>
<to type="redirect" last="true">/events$2</to>
This will match any thing and take everything from the beginning of query string till the first occurrence of #
Explanation:
Group 1 : Match the url /event/showEventList.html OR /event/showEventList.htm
Group 2 : Match all query string between o to many till the first occurrence of #
Group 2 is the string which you want to use for redirect and ignore any thing after # including #
Example:

I am answering my own question, so that in future if someone else stumbles upon the same problem, this answer could help him.
There is nothing to do with the UrlRewriteFilter framework. By enabling the debug log for this framework I have seen that the URL it is receiving before applying the defined rules doesn't have the URL Hash(#). From other SO answers and by analyzing the network traffic of the browser, I saw that the browser does not send the URL fragment to the server so it's not available in the HttpServletRequest. This is the reason the Regular Expressions are not working.
Since this hash is available in the client browser and thanks to HTML5 History API I am able to solve the problem using JavaScript:
<script type="text/javascript">
window.addEventListener('DOMContentLoaded', (event) => {
const url = new URL(window.location);
url.hash = '';
history.replaceState(null, document.title, url);
});
</script>

Eclipse To replace two same line

By mistakenly i have replace couple of line in all the java files by using global replace (CTRL + H) function.
as currently text is as below :-
data.creationtime = DateUtils.convertDateTimeFromServer(data.creationtime);
data.creationtime = DateUtils.convertDateTimeFromServer(data.creationtime);
and i want to replace last line with correct word as below :-
data.creationtime = DateUtils.convertDateTimeFromServer(data.creationtime);
data.modificationtime = DateUtils.convertDateTimeFromServer(data.modificationtime);
i am not sure how to do it because i have two identical lines , can some one please guide me ?
i have followed this link but regex patterns is not working
SOLUTION
I have tried below pattern and it worked
For Match :-
(data.creationtime = DateUtils.convertDateTimeFromServer\(data.creationtime\);\s*?data.)([^ ]+?)( = DateUtils.convertDateTimeFromServer\(*?data.)([^ ]+?)(\);)
For Replace :- $1modificationtime$3modificationtime$5

Maybe not the most efficient way, but it should work.
Search-Pattern:
(data.creationtime = DateUtils.convertDateTimeFromServer\(data.creationtime\);\s*?data.)([^ ]+?)( = DateUtils.convertDateTimeFromServer\(data.creationtime\);)
Replacement-Pattern:
$1modificationtime$3

Jenkins Console section: What Java regex will trigger on string ERROR but not on string %%ERRORLEVEL%%?

I am using the Jenkins console sections plugin [1] on a windows server. It is excellent in order to make a nice left navbar on my logs.
Positively, I would like any error message to cause a section header, eg;
Assert-PathExstsNotTooLong : ERROR, The path does not exist: E:\P...
...
Oops! Error, please do not do that.
Negatively, I would like to be able to avoid having spelled-out execution templates cause a new section header, eg the below.
[workspace] $ cmd.exe /C " c:\Windows\Microsoft.NET\Framework64\v4.0.30319\MSBuild.exe /p:Configuration=Debug /p:VisualStudioVersion=12.0 "E:\Program Files (x86)\Jenkins\jobs\M.sln"
Using references here on SO [2] and on the tester you recommended [3], I came up with the following, but it is not working?
^(?=(.*([Ee][Rr][Rr][Oo][Rr] ).*))(?!(%%ERRORLEVEL%%))
Using Regex101's amazing tester, with JS flavor, I used the above as input and had these test strings and outputs. The second line of match info perhaps explains my issue but I do not understand it.
test-strings =
help error you should see me
i am %%errorlevel%% again
i am not a section
match-info;
1. `help error you should see me`
2. `error `
Any tips?
thank you!

(I can't add comments yet, otherwise I'd ask directly, but your example of a spelled-out message template doesn't include the text %%ERRORLEVEL%%, but I assume that it's meant to be a string with %%ERRORLEVEL%% somewhere in the middle of it. Also, as the example isn't quite right, I can't tell exactly what you mean by "not working")
Your problem is that your regex matches ERROR_ (with a space) anywhere in the text, except where the text is exactly %%ERRORLEVEL%%. I think that instead you could write:
^(?=(.*([Ee][Rr][Rr][Oo][Rr])))(?!.*(%%ERRORLEVEL%%)).*
Do you really need to only match ERROR_ (with a space) as opposed to ERROR (whether or not it has a space)? If the former, then you are already excluding %%ERRORLEVEL%%, and you could just use .*(?i:ERROR ).* as the full regex.
The Collapsing Console Sections Plugin uses Java regular expressions, so you can use (?i:ERROR) to match ERROR case-insensitively.
You need a trailing .* before and after your negative-lookahead atom for %%ERRORLEVEL%%, otherwise it will only exclude an exact match
The documentation for the plugin doesn't say whether the pattern has to match a line completely, or if it just matches text within the line. If it matches the line completely, the leading ^ is unnecessary, but won't be doing any harm.
You've got capturing brackets around ERROR and %%ERRORLEVEL%%. If you're not doing anything with that text, then those brackets are unnecessary.
The following regex will match any line with any of ERROR, Error, error etc in it, except lines with any of %%ERRORLEVEL%%, %%ErrorLevel%%, %%errorlevel%% etc.
^(?=.*(?i:ERROR))(?!.*(?i:%%ERRORLEVEL%%)).*

Capturing dot and comma in Java RegExp

I have following code in Java:
Pattern fieldsPattern = Pattern.compile("(\"([^\"]+)\")|"
+"("+this.field_tag+"([0-9a-zA-Z_]+))");
Matcher fieldsMatcher = fieldsPattern.matcher(field);
while(fieldsMatcher.find())
{
//...
}
This code should capture expressions like "expression" and :expression (field_tag is just ":"). The problem occurs when I try to capture an expression like: "10.1" or "10,1". It dosen't work.
But expressions:
"10-1",
"10+1"
works as expected.
I also tried use this regexp on regexpal.com - site with javascript implementation of RegExp. On this site expressions like "10.1" and "10,1" works fine.
Is there any difference in java vs javascript in capturing dots? What am I doing wrong?

This works for me
Pattern fieldsPattern = Pattern.compile("(\"[^\"]+\")");
String field =" aa \"10\" \"10.1\" and \"10,1\"";
Matcher fieldsMatcher = fieldsPattern.matcher(field);
while(fieldsMatcher.find()) {
System.out.println(fieldsMatcher.group());
}
prints
"10"
"10.1"
"10,1"
The second set of brackets in the regex appear to be redundant, but are harmless.
