I have a link by this text,
s= "http://xyz.com/Getid.ashx?JobID=250920&JobTitle=office+junior&seswitch=1&lid=801&AVSDM=2012-11-22+11%3a33%3a00"
I need to extract two information from this link
1)JobID which "250920"
2)JobTitle which is "office junior"
Is this possible by using gsub will I be able to get only those text from the link?
You can try .match with a regex:
result = s.match(/JobID\=(\d+).+JobTitle\=([a-zA-Z+0-9]+)\&/)
result[1] #JobID
result[2] #JobTile

I have an exported product list from Shopify. I need to translate the product description but in the exported description there are HTML codes that Have to stay intact. How do I exclude the code from my translation?
I use =googletranslate
What can i add in my function to exclude all text between <> theese
You can strip tags with this function
function stripTags(body) {
var regex = /(<([^>]+)>)/ig;
return body.replace(regex,"");
}
use:
=REGEXREPLACE(A1; "</?\S+[^<>]*>"; )
or:
=REGEXREPLACE(A1; "<\/\w+>|<\w+.*?>"; )
I'm using stringscanner on my request URL in order to get the name of the user's currently selected category, but I've been having difficulty dealing with spaces and special characters.
request.url.scan(/\?category=\w+/).to_s.gsub('?category=', '')
URL examples followed by result
http://localhost:3000/search?category=dog&search=&utf8=%E2%9C%93 => ["dog"]
http://localhost:3000/search?category=dog.com&search=&utf8=%E2%9C%93 => ["dog"]
http://localhost:3000/search?category=dog+cat&search=&utf8=%E2%9C%93 => ["dog"]
I'm trying to get ["dog"] ["dog.com"] and ["dog cat"], but am currently stuck. Any ideas?
Note: Considering removing spaces from categories and replacing them with dashes as multiple spaces could be problematic, but if it's possible to create one function to rule them all, that would be awesome.
This is Rails, is there a reason you're not just using params[:category]?
If you are trying to extract params then you could use parse_query :
uri = "http://localhost:3000/search?category=dog+cat&search=&utf8=%E2%9C%93"
result = Rack::Utils.parse_query(URI(uri).query) #=> {"category"=>"dog cat", "search"=>"", "utf8"=>"\xE2\x9C\x93"}
result["category"] #=> dog cat
I have an automated report tool (corp intranet) where the admins have a few text area boxes to enter some text for different parts of the email body.
What I'd like to do is parse the contents of the text area and wrap any hyperlinks found with link tags (so when the report goes out there are links instead of text urls).
Is ther a simple way to do something like this without figuring out a way of parsing the text to add link tags around a found (['http:','https:','ftp:] TO the first SPACE after)?
Thank You!
Ruby 1.87, Rails 2.3.5
Make a helper :
def make_urls(text)
urls = %r{(?:https?|ftp|mailto)://\S+}i
html_text = text.gsub urls, '\0'
html_text
end
on the view just call this function , you will get the expected output.
like :
irb(main):001:0> string = 'here is a link: http://google.com'
=> "here is a link: http://google.com"
irb(main):002:0> urls = %r{(?:https?|ftp|mailto)://\S+}i
=> /(?:https?|ftp|mailto):\/\/\S+/i
irb(main):003:0> html = string.gsub urls, '\0'
=> "here is a link: http://google.com"
There are many ways to accomplish your goal. One way would be to use Regex. If you have never heard of regex, this wikipedia entry should bring you up to speed.
For example:
content_string = "Blah ablal blabla lbal blah blaha http://www.google.com/ adsf dasd dadf dfasdf dadf sdfasdf dadf dfaksjdf kjdfasdf http://www.apple.com/ blah blah blah."
content_string.split(/\s+/).find_all { |u| u =~ /^https?:/ }
Which will return: ["http://www.google.com/", "http://www.apple.com/"]
Now, for the second half of the problem, you will use the array returned above to subsititue the text links for hyperlinks.
links = ["http://www.google.com/", "http://www.apple.com/"]
links.each do |l|
content_string.gsub!(l, "<a href='#{l}'>#{l}</a>")
end
content_string will now be updated to contain HTML hyperlinks for all http/https URLs.
As I mentioned earlier, there are numerous ways to tackle this problem - to find the URLs you could also do something like:
require 'uri'
URI.extract(content_string, ['http', 'https'])
I hope this helps you.
I'm writing a site with a custom tweet button that uses the www.twitter.com/share function, however the problem I am having is including hash '#' characters within the tweet text.
For example:
http://www.twitter.com/share?url=www.example.com&text=I+am+eating+#branstonpickel+right+now
The tweet text comes out as 'I am eating' and omits the hash and everything after.
I had a quick look on the Twitter forums and learnt the hash '#' character cannot be part of the share url. On https://dev.twitter.com/discussions/512#comment-877 it was said that:
Hashes are special characters in the URL (they identify document fragments) so they, and anything following, does not get sent the server.
and
you need to URLEncode it, so use %23
When I tried the 2nd point in my test link:
www.twitter.com/share?url=www.example.com&text=I+am+eating+%23branstonpickel+right+now
The tweet text came out as 'I am eating %23branstonpickel right now' literally including %23 instead of converting it to a hash.
Sorry for the waffely question, but does anyone know what it is I'm doing wrong?
Any feedback would be greatly appreciated :)
It looks like this is the basic setup:
https://twitter.com/intent/tweet?
url=<url to tweet>
text=<text to tweet>
hashtags=<comma separated list of hashtags, with no # on them>
This would pre-built a tweet of: <text> <url> <hashtags>
The above example would be:
https://twitter.com/intent/tweet?url=http://www.example.com&text=I+am+eating+branston+pickel+right+now&hashtags=bransonpickel,pickles
There used to be a bug with the hashtags parameter... it only showed the first n-1 hashtags. Currently this is fixed.
you can use %23 instead of hash (#) in url eg
http://www.twitter.com/share?url=www.example.com&text=I+am+eating+%23branston+%23pickel+right+now
I may be wrong but i think the hashtag has to be passed as a separate variable that will appear at the end of your tweet ie:
http://www.twitter.com/share?url=www.example.com&text=I+am+eating+branston+pickel+right+now&hashtag=bransonpickel
will result in "I am eating branston pickel right now #branstonpickle"
On a separate note, I think pickel should be pickle!

use encodeURIComponent to encode the url
If you're using PHP, you can use the following:
<?php echo 'http://www.twitter.com/share?' . http_build_query(array(
'url' => 'http://www.example.com',
'text' => 'I am eating #branstonpickel right now'
)); ?>
This will do all the URL encoding for you, and it's easy to read.
For more information on the http_build_query, see the PHP manual:
http://us2.php.net/http_build_query
For url with line jump, # , # and special unicode in it, the following works :
var lineJump = encodeURI(String.fromCharCode(10)),
hash = "%23", arobase="%40",
tweetText = 'https://twitter.com/intent/tweet?text=Le signe chinois '+hans+' '+item.pinyin+': '+item.definition.replace(";",",")+'.'
+lineJump+'Merci '+arobase+'Inalco_Officiel '+arobase+'CRIparis ❤️🇨🇳 '
+lineJump+hash+'Chinois '+hash+'MOOC'
+lineJump+'https://hanzi.cri-paris.org/',
tweetTxtUrlEncoded = tweetText+ "" +encodeURIComponent('#'+lesson+encodeURIComponent(hans));
urlencode
https://twitter.com/intent/tweet?text=<?= urlencode("I am eating #branstonpickel right now"); ?>"
You can just use this code and modify it
20% means space
23% means hashtag
In JS you can easily encode the special characters using encoreURIComponent.
(Warning: don't use encodeURI as "#" and "#" are not escaped.)
Here's an example with mention and hashtag:
const text = "Hello #world ! Go follow #StackOverflow";
const tweetUrl = `https://twitter.com/intent/tweet?text=${ encodeURIComponent(text) }`;
I'm importing an RSS feed which has a series of empty paragraphs "<p> </p>".
I am using gsub however it's not stripping the elements from the document:
document.gsub(/<p>\s*<\/p>/,"") or gsub(/<p> <\/p>/,"")
Is there an alternative method or a mistake in the above?
The below appears to work?
gsub(/<p>.<\/p>/,"")
Correct regex like in example:
>> document = "<p>\n\n\n \n</p>aaa<p> </p>bbb"
=> "<p>\n\n\n \n</p>aaa<p> </p>bbb"
>> document.gsub(/<p>[\s$]*<\/p>/, '')
=> "aaabbb"
If the paragraph elements in your RSS feed uses id and classes try this:
gsub(/\<p(\s((class)|(id))=[\'\"][A-z0-9\s]+[\'\"]\s*)*\>\s*\<\/p\>/,"")
