How to remove some text in edit.text with exceptions?
I want to remove all text except the text that I want to keep.
ex : "THIS IS THE TEXT"
Then i want to remove all text except "THIS" and "TEXT"
After removing the result will be like this:
"THIS TEXT"
I was wondering if StringReplace() wouldn't be working if the text have a changeable context. Or maybe StringReplace() will be working in this case with another method?
You can do this
string s = "THIS IS THE TEXT";
string v = s.Replace("IS THE", "");
Hopefully, it will solve your problem

I have an UItextView and i set the AttributedText at the starting of the app so with en empty text because user didn't yet fill anything. The problem is that with an empty String the AttributedText seam to not apply for the new text i will enter. how to do ?
As far as I know there is no straight solution for that. Setting AttributedText with "" doesn't work.
However you can do easy fix:
if let text = field.attributedText?.string {
//normal way
} else {
field.font = ...
field.fontColor = ...
//sorry, no shadow and other nice tricks
}
Of course you could implement delegate to text field and adjust attributes when textFieldDidChange, but that doesn't work well with typing in Chinese language where letter can be composed from multiple characters so I couldn't use that.
Let's say I have some text in rails:
text = "A bunch of data goes in here: %#user.name%#, %#user.email%#, %#company.name%#, %#company.state%# and then some other information as well"
I am looking for the best way to parse through that text looking for all substrings between %# and another %# in order to replace it with actual data. The text should not anticipate that data will be in any particular order and it should ideally be able to turn the substrings into references to local variables that match the substring.
Use the String#scan method.
For your case in particular, the regex I used to match was: /(\%\#.*?\%\#)/
text = "A bunch of data goes in here: %#user.name%#, %#user.email%#, %#company.name%#, %#company.state%# and then some other information as well"
regex = /(\%\#.*?\%\#)/
#here's the one line version
text.scan(regex).each {|match| text.sub!(match[0], eval(match[0].gsub(/[\%\#]/, '')))}
#Here's the more organized version
text.scan(regex).each do |match|
current_match = match[0]
replacement_var = current_match.gsub(/[\%\#]/, '')
text.sub!(current_match, eval(replacement_var))
end
puts text
text = "A bunch of data goes in here: %#user.name%#, %#user.email%#, %#company.name%#, %#company.state%# and then some other information as well"
placeholder = text[/\%\#.*?\%\#/]
while placeholder
case placeholder
when "%#user.name%#"
text.sub!(/\%\#.*?\%\#/,"Steve")
when "%#user.email%#"
text.sub!(/\%\#.*?\%\#/,"steve#example.com")
when "%#company.name%#"
text.sub!(/\%\#.*?\%\#/,"Wayne Industries")
when "%#company.state%#"
text.sub!(/\%\#.*?\%\#/,"Gotham")
else
text.sub!(/\%\#.*?\%\#/,"unknown")
end
placeholder = text[/\%\#.*?\%\#/]
end
I need to import text from txt file with some variables. I use BufferedReader and File Reader. In code I have :
String car = "vw golf";
String color = "nice sunny blue color";
And in my txt file:
I have nice " +car+ " which has "+color+".
My expected output :
I have nice vw golf which has nice sunny blue color.
My actual output is :
I have nice " +car+ " which has "+color+".
If I've understood correctly, what you want to do is replace " + car + " with the value of your car string and likewise for colour. You've tried to do this by writing your text file as if it were a command to be evaluated. However, that won't happen - it will just be outputted as is. I'm going to assume you are using c#. What you need to do is, prior to outputting your string, parse it to replace the markers with the variables. I would recommend you get rid of the double quotes in your text file. You could then do something like this:
string text = this.ReadTextFromFile();
string ammended = text.Replace("+car+", car);
As mentioned, this is assuming you remove the double quotes from your text file so it reads:
I have nice +car+ which has +color+.
Also, you don't need to use the + symbols, but I suppose they are a good way of designating a unique token to be replaced. You could use {car} in the file and then likewise in the Replace startment, for example.
I may not have properly understood what you wanted to do, of course!
Edit: Incase of confustion,
this.ReadTextFile();
was just a short hand way of saying that the text variable contains the contents as read from your text file.
I have a lot of html files that I want to add a rel="nofollow" to all the a href tags that are into a specific div.
I think c# code can do it. But how do I relate only partial code..?
Any suggestion? also I didnt realy know
Here is what I think:
Parse the HTML line by line
Look for " block start you would need to find the means look for "/div>".
Store all the content between "" into a string
check if "href=" is found and how many
Now parse this string again to search all "" and match with "href=" counter
#5 will give you an array of "href=" tag based lines
Now you can assume every "href=" tag must have ">" at the end of the "
At the last this is what you can do:
string s1 = " this is link ";
string s2 = s1.Insert(s1.IndexOf(">"), " rel=\"nofollow\"");
I searched but nothing explains how to do this,
for example
Dim sentence as String = "cat is an animal"
if i make a msgbox :
MsgBox(sentence)
it shows
cat is an animal
how to make a msgbox that says
cat
is
an
animal.
Easy way Replace space with new line
as in string words = MyString.Replace(" ","\r\n")
Split would be split on space in to an array , and then join that back up with new lines which is pointless unless you need the array for something else.
