I am trying to exclude delimiters within text qualifiers. For this, I am trying to use Regex. However, I am new to Regex and am not able to fully accomplish my needs. I would be very greatful if someone can help me out.
In Alteryx, I load a delimited flat text file as 'non-delimited' and say that it does not have text qualifiers. Thus, the input will look something like this:
"aabb"|ccdd|eeff|gghh
"aa|bb"|ccdd|eeff|gghh
"aa|bb"|ccdd|"ee|ff"|gghh
"aa|bb"|"cc|dd"|"ee|ff"|"gg|hh"
"aabb"|"ccdd"|"eeff"|"gghh"
"aabb"|"ccdd"|"eeff"|"gg|hh"
aabb|ccdd|eeff|gghh
"aa|bb"|ccdd|eeff|"gg|hh"
aabb|cc|dd|eeff|gghh
aabb|"cc||dd"|eeff|gghh
aabb|"c|c|dd"|eeff|gghh
"aa||bb"|ccdd|eeff|gghh
"a|a|b|b"|ccdd|eeff|gghh
"aabb"|ccdd|eeff|"g|g|hh"
"aabb"|ccdd|eeff|"gg||hh"
I want to exclude all delimiters that are in between text qualifiers.
I have tried to use Regex to replace the delimiters within text qualifiers with nothing.
So far, I have tried the following Regex code for my target:
(")(.*?[^"])\|+(.*?)(")
And I have used the following for my replace:
$1$2$3$4
However, this will not fix te lines 11, 13, 14 and 15.
I wish to obtain the following results:
"aabb"|ccdd|eeff|gghh
"aabb"|ccdd|eeff|gghh
"aabb"|ccdd|"eeff"|gghh
"aabb"|"ccdd"|"eeff"|"gghh"
"aabb"|"ccdd"|"eeff"|"gghh"
"aabb"|"ccdd"|"eeff"|"gghh"
aabb|ccdd|eeff|gghh
"aabb"|ccdd|eeff|"gghh"
aabb|cc|dd|eeff|gghh
aabb|"ccdd"|eeff|gghh
aabb|"ccdd"|eeff|gghh
"aabb"|ccdd|eeff|gghh
"aabb"|ccdd|eeff|gghh
"aabb"|ccdd|eeff|"gghh"
"aabb"|ccdd|eeff|"gghh"
Thank you in advance for helping me out!
With kind regards,
Robin
I can't think of the correct syntax in REGEX unless you are putting in each pattern that could be found.
However, an easier way (maybe not as performant), would be to use a Text to Columns selecting Ignore delimiters in quotes. If you need it back together in one cell afterwards, you can transpose, then remove delimiters followed by a Summarize to concatenate each RecordID Group.

I have some urls saved in DB like hello world
with break tags, so i need to delete them, the problem that <br/> are in other places to so i can't delete all of them,
i write RegExp <*"*<br\/?>"> but it select not only <br> and quotes too.
You really shouldn't be using regular expressions for parsing HTML or XML.
Having said that. As I understand it, you have br tags inside the href attribute of a tags.
try :
href\s*?=\s*?\"(.*?)(<br\/?\>)\"
If you try to search about the right lines in the database, then this is your regex extended to match the whole line:
<.*\".*<br\/>\">.*>
After this you can mach the '<br/>' directly in those lines. Is there a language to edit your DB?
Some of the other answers here are okay. I'll offer an alternative:
https://regex101.com/r/uG5PBA/2
This'll put the break tags in a capture group -- group 1, so that you can simply nix them.
Regex:
<a[\s\S]*?(\<br\/>)[\s\S]*?<\/a>
Test String:
hello worldhello world
I have a csv in following format.
id,mobile
1,02146477474
2,08585377474
3,07646474637
4,02158789566
5,04578599525
I want to add a new column and add just leading 3 numbers to that column (for specific cases and all the others NOT_VALID string). So result should be:
id,number,provider
1,02146477474,021
2,08585377474,085
3,07646474637,NOT_VALID
4,02158789566,021
5,04578599525,NOT_VALID
I can use following regex for replacing that. But I would like to use all possible conversations in one step. Using UpdateRecord processor.
${field.value:replaceFirst('085[0-9]+','085')}
When I use something like this:
${field.value:replaceFirst('085[0-9]+','085'):or(${field.value:replaceFirst('086[0-9]+','086')}`)}
This replaces all with false.
Nifi uses Java regex
As soon, as you are using record processing, this should work for you:
${field.value:replaceFirst('^(021|085)?.*','$1')}
The group () optionally ? catches 021 or 085 at the beginning of string ^
The replacement - $1 - is the first group

I am trying to match everything between multiple set of brackets
Example of data
[[42.30722,-83.181125],[42.30722,-83.18112667],[42.30722167,-83.18112667,[42.30721667,-83.181125],[+42.30721667,-83.181125]]
I need to match everything within the inner brackets as below
42.30722,-83.181125,
42.30722,-83.18112667,
42.30722167,-83.18112667,
42.30721667,-83.181125,
+42.30721667,-83.181125
How do I do that. I tried \[([^\[\]]|)*\] but it gives me values with brackets. Can anybody please help me with this. Thanks in advance
Seems like one of them is missing a bracket maybe, or if not, maybe some expression similar to:
\[([+-]?\d+\.\d+)\s*,\s*([+-]?\d+\.\d+)\s*\]?
might be OK to start with.
Test
import re
expression = r"\[([+-]?\d+\.\d+)\s*,\s*([+-]?\d+\.\d+)\s*\]?"
string = """
[[42.30722,-83.181125],[42.30722,-83.18112667],[42.30722167,-83.18112667,[42.30721667,-83.181125],[+42.30721667,-83.181125]]
"""
print([list(i) for i in re.findall(expression, string)])
print(re.findall(expression, string))
Output
[['42.30722', '-83.181125'], ['42.30722', '-83.18112667'], ['42.30722167', '-83.18112667'], ['42.30721667', '-83.181125'], ['+42.30721667', '-83.181125']]
[('42.30722', '-83.181125'), ('42.30722', '-83.18112667'), ('42.30722167', '-83.18112667'), ('42.30721667', '-83.181125'), ('+42.30721667', '-83.181125')]
If you wish to simplify/modify/explore the expression, it's been explained on the top right panel of regex101.com. If you'd like, you can also watch in this link, how it would match against some sample inputs.
A little late, but figured I would include it anyhow.
Your 3rd set is missing a ']'.
If that is in there, then in Alteryx, you can just use Text to Columns splitting to Rows and ignore delimiter in brackets
Trying to use Sublime to update the urls of only some lines in a sql table dump.
in this case the line that I need to single out has the string 'themo_showcase_\d_image' which is easy to match. In the same string what I actually need to replace is the url column so that it reads 'https://www.example.com/' to 'http://www.example.com'
Anyone able to help shed some light on this? I've got thousands of these insert records that I need to modify.
ex:
original string:
('8630', '1328', 'themo_showcase_1_image', 'https://www.example.com/'),
to:
('8630', '1328', 'themo_showcase_1_image', 'http://www.example.com/'),
Find: 'themo_showcase_\d_image', 'http\Ks you could use \d+ if there are more than 1 digit
Replace: LEAVE EMPTY
I'm edit an rst file for a document. There are lot of image links I have to edit them one by one, I'd like to ask, is there anybody can help write a regular expression that can transfer it in one time.
The original text looks like:
*Figure 1.2: Where is the dog?* <dog.html#fig_dog>
I'd like it translate it to:
:ref:fig_dog
And there is another one:
*How are you* <how_are_you.html>
I'd like it translate it to:
:ref:how_are_you
I have try some expression in editplus or notepad++, but i can't match them very well.
Search:
\*.*?\*\s*<(?:.*#)?([^.>]+)(\.[^>]*)?>
Replace:
:ref:\1
split into two regexes
To match before the html
<(.*).html.*?>
To match the anchor
<.*.html#(.*?)>
