I'm trying to work out a regex pattern to match URL's.
I currently have URL structures like so
walks/category/catname
walks/category/catname/P12
walks/category/catname/P24
I want to be able to match them and replace them so they end up like so
walks/catname
walks/catname/p2
walks/catname/p3
(where catname is a variable)
So far I had
/walks/category/(.*) to /walks/$1
Which seems to work for the first page of results, but obviously not for the paginated ones.
I'm ab bit stuck so any pointers would be very much appreciated.
Thanks!
Sort of like
Find walks/.*?(/catname.*)
Replace walks$1
Construct the regex to insert the catname variable
var regex = 'walks/.*?(/' + vCatname + '.*)'
before:
walks/category/catname
walks/category/catname/P12
walks/category/catname/P24
after:
walks/catname
walks/catname/P12
walks/catname/P24

I am trying to replace substrings that look like the following
Education|AAA|BBB|CCC|DDD|EEE
AAA|Educator|CCC|DDD|EEE
where Education or Educator could be in any position of the pipe delimited string. They are present at most only one time or zero times
I need to replace them with Educator/Education
What I want is
Educator/Education|AAA|BBB|CCC|DDD|EEE
AAA|Educator/Education|CCC|DDD|EEE
This works on the first pass with Education, I get
Educator/Education|AAA|BBB|CCC|DDD|EEE
AAA|Educator|CCC|DDD|EEE
But on the second pass replacing Educator, I get
Educator/Education/Education|AAA|BBB|CCC|DDD|EEE
AAA|Educator/Education|CCC|DDD|EEE
I think different a RegEx pattern for the ReplaceNth function would do it but cannot get what it should be
This is what I came up with in my limited ability with Google Script, which I got mostly from cobbling together from searches
Thanks
Edit: Updated with Wiktors solution given in a comment
function FRCrit_n(){
FRCrit("Elements", "Combined-What Are The Primary Role(s) Being Play?");
}
function FRCrit(shtName,cheader){
var sh = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(shtName);
var data = sh.getDataRange().getValues();
var col =HTN(shtName,cheader)-1; //Header to column index
for(n=1;n<data.length;++n){
data[n][col] = data[n][col].replace(/\bEducat(?:or|ion)\b/g, 'Educator/Education')[col],"Education","Educator/Education",1)
}
sh.getRange(1,1,data.length,data[0].length).setValues(data);
}
In regular expression syntax, you can create an 'or' condition using a vertical bar to search for multiple things in one go. You can test this out in G Suite Sheets without needing any code.
I think you want to search for
Education|Educator
and replace it with
Education/Educator
When you are happy with your results you can put it back into code - the same regex syntax should work in javascript.
I'm trying to create a custom filter in Google Analytic to remove the query parts of the url which I don't want to see. The url has the following structure
[domain]/?p=899:2000:15018702722302::NO:::
I would like to create a regex which skips the first 12 characters (that is until:/?p=899:2000), and what ever is going to be after that replace it with nothing.
So I made this one: https://regex101.com/r/Xgbfqz/1 (which could be simplified to .{0,12}) , but I actually would like to skip those and only let the regex match whatever is going to be after that, so that I'll be able to tell in Google Analytics to replace it with "".
The part in the url that is always the same is
?p=[3numbers]:[0-4numbers]
Thank you
Your regular expression:
\/\?p=\d{3}\:\d{0,4}(.*)
Tested in Golang RegEx 2 and RegEx101
It search for /p=###:[optional:####] and capture the rest of the right side string.
(extra) JavaScript:
paragraf='[domain]/?p=899:2000:15018702722302::NO:::'
var regex= /\/\?p=\d{3}\:\d{0,4}(.*)/;
var match = regex.exec(paragraf);
alert('The rest of the right side of the string: ' + match[1]);
Easily use "[domain]/?p=899:2000:15018702722302::NO:::".substr(12)
You can try this:
/\?p\=\d{3}:\d{0,4}
Which matches just this: ?p=[3numbers]:[0-4numbers]
Not sure about replacing though.

As I write this I realise there are two parts to this question, however I think I am only really stuck on the first part and therefore the second is only provided for context:
Part A:
I need to search the contents of each value returned by a for loop (where each value is a url) for the following:
href="/dir/Sub_Dir/dir/163472311232-text-text-text-text/page-n"
where:
the numerals 163472311232 could be any length (ie it could be 5478)
-text-text-text-text could be any number of different words
where page-n could be from page-2 up until any number
where matches are not returned more than once, ie only unique matches are returned and therefore only one of the following would be returned:
href="/dir/Sub_Dir/dir/5422-la-la/page-4
href="/dir/Sub_Dir/dir/5422-la-la/page-4
Part B:
So the logic would be something like:
list_of_urls = original_list
for url in list_of_urls:
headers = {'User-Agent' : 'Mozilla 5.0'}
request = urllib2.Request(url, None, headers)
url_for_re = urllib2.urlopen(request).read()
another_url = re.findall(r'href="(/dir/Sub_dir\/dir/[^"/]*)"', url_for_re, re.I)
file.write(url)
file.write('\n')
file.write(another_url)
file.write('\n')
Which i am hoping will give me output similar to:
a.html
a/page-2.html
a/page-3.html
a/page-4.html
b.html
b/page-2.html
b/page-3.html
b/page-4.html
So my question is (assuming the logic in part B is ok):
What is the required regex pattern to use for part A?
I am a newbie to python and regex so this will limit my understanding somewhat in regards to relatively complicated regex suggestions etc.
update:
after suggestions i tried to test the following regex which did not produce any results:
import re
content = 'href="/dir/Sub_Dir/dir/5648342378-text-texttttt-texty-text-text/page-2"'
matches = re.findall(r'href="/dir/Sub_Dir/dir/[0-9]+-[a-zA-Z]+-[a-zA-Z]+-[a-zA-Z]+-[a-zA-Z]+/page-([2-9]|[1-9][0-9]+)"', content, re.I)
prefix = 'http://www.test.com'
for match in matches:
i = prefix + match + '\n'
print i
solution:
i think this is the regex that will work:
matches = re.findall(r'href="(/dir/Sub_Dir/dir/[^"/]*/page-[2-9])"', content, re.I)
You can have... most of what you want. Regexes don't really do the distinct thing, so I suggest you just use them to get all the URLs, and then remove duplicates yourself.
Off the top of my head it would be something like this:
href="/dir/Sub_Dir/dir/[0-9]+-[a-zA-Z]+-[a-zA-Z]+-[a-zA-Z]+-[a-zA-Z]+/page-([2-9])|([1-9][0-9]+)"
Plus or minus escaping rules, specifics on what words are allowed, etc. I'm a Windows guy, there's a great tool called Expresso which is helpful for learning regexes. I hope there's an equivalent for whatever platform you're using, it comes in handy.
Can someone assist in creating a Regex for the following situation:
I have about 2000 records for which I need to do a search/repleace where I need to make a replacement for a known item in each record that looks like this:
<li>View Product Information</li>
The FILEPATH and FILE are variable, but the surrounding HTML is always the same. Can someone assist with what kind of Regex I would substitute for the "FILEPATH/FILE" part of the search?
you may match the constant part and use grouping to put it back
(<li>View Product Information</li>)
then you should replace the string with $1your_replacement$2, where $1 is the first matching group and $2 the second (if using python for instance you should call Match.group(1) and Match.group(2))
You would have to escape \ chars if you're using Java instead.
I made an article spinner that used regex to find words in this syntax:
{word1|word2}
And then split them up at the "|", but I need a way to make it support tier 2 brackets, such as:
{{word1|word2}|{word3|word4}}
What my code does when presented with such a line, is take "{{word1|word2}" and "{word3|word4}", and this is not as intended.
What I want is when presented with such a line, my code breaks it up as "{word1|word2}|{word3|word4}", so that I can use this with the original function and break it into the actual words.
I am using c#.
Here is the pseudo code of how it might look like:
Check string for regex match to "{{word1|word2}|{word3|word4}}" pattern
If found, store each one as "{word1|word2}|{word3|word4}" in MatchCollection (mc1)
Split the word at the "|" but not the one inside the brackets, and select a random one (aka, "{word1|word2}" or "{word3|word4}")
Store the new results aka "{word1|word2}" and "{word3|word4}" in a new MatchCollection (mc2)
Now search the string again, this time looking for "{word1|word2}" only and ignore the double "{{" "}}"
Store these in mc2.
I can not split these up normally
Here is the regex I use to search for "{word1|word2}":
Regex regexObj = new Regex(#"\{.*?\}", RegexOptions.Singleline);
MatchCollection m = regexObj.Matches(originalText); //How I store them
Hopefully someone can help, thanks!
Edit: I solved this using a recursive method. I was building an article spinner btw.
That is not parsable using a regular expression, instead you have to use a recursive descent parser. Map it to JSON by replacing:
{ with [
| with ,
wordX with "wordX" (regex \w+)
Then your input
{{word1|word2}|{word3|word4}}
becomes valid JSON
[["word1","word2"],["word3","word4"]]
and will map directly to PHP arrays when you call json_decode.
In C#, the same should be possible with JavaScriptSerializer.
I'm really not completely sure WHAT you're asking for, but I'll give it a go:
If you want to get {word1|word2}|{word3|word4} out of any occurrence of {{word1|word2}|{word3|word4}} but not {word1|word2} or {word3|word4}, then use this:
#"\{(\{[^}]*\}\|\{[^}]*\})\}"
...which will match {{word1|word2}|{word3|word4}}, but with {word1|word2}|{word3|word4} in the first matching group.
I'm not sure if this will be helpful or even if it's along the right track, but I'll try to check back every once in a while for more questions or clarifications.
