Converting a text file into String array with regular expression

I have a .txt file which contains above 1000 words
sample city names below
Razvilka
Moscow
Firozpur Jhirka
Kathmandu
Kiev
Pokhara
Merida
Delhi
Reshetnikovo
Ciudad Bolivar
Marfino
Zhukovskiy
Reutov
Kurovskoye
etc
I would like to have these words in this format below
"Razvilka","Moscow","etc","etc"
enclosed with double quotation and with a comma in the end.I am using Notepad++.Could you mention how to do it and which software should I use it?

If you're using Notepad++, make a Search and Replace replacing
\b(\w+)\b
with
"$1",
It'll find all words and replace with them self, surrounded by quotes. You'll have to manually remove the last , if that's unwanted.

I wonder if this question is about programming, but You tagged android, regex and android studio, so I guess it is. If yes, You can simply split a string in that way:
String[] splitted = yourString.split("\\s+");
In that case, You are splitting the strings by whitespaces (this regex is also for more than one whitespace), like Your string seems to be. If You have more than one delimiter, You can do it by using the OR operator |
String[]splitted = yourString.split("-|\\.");
In that example, You are splitting the String by - and . (minus and point). The delimiter is the sign where the String is splitted by.

Password regex string in strings.xml file in android

I have declared a regex for password validation purposes in strings.xml file.
The criteria is
-should be atleast 8 characters
-should contain atleast one upper case letter
-should contain atleast one lower case letter
-should contain atleast one special character within these "##$%^+&="
So my whole regex looks like this now
^(?=.[0-9])(?=.[a-z])(?=.[A-Z])(?=.[##$%^+&=])(?=\S+$).{8,}$
But when I enter this, I get an error saying that & is
"Unescaped or non terminated character entity/reference"
So instead I used the escape sequence as & but the validation fails for &
I would b glad if anyone could help me out on this!!

Use * quantifers in the look-aheads. Right now, you check if 2nd character in the string meets your conditions. We need to test them all in the string.
^(?=.*[0-9])(?=.*[a-z])(?=.*[A-Z])(?=.*[##$%^+&=])(?=\S+$).{8,}$
Here is a demo.
EDIT
Since the regex is located inside the XML code, it should be properly encoded. Or, use it inside CDATA block.

Are you missing a parameter in your curly braces? The last bit "{8,}" seems off.

What is the the double quotation marks in strings.xml used for?

Just a little while ago, I was looking around on GitHub， and I found there were some double quotation marks beside the string value in some strings.xml just like this:
<string name="ClipMmi" msgid="6952821216480289285">"来电显示"</string>
In short I mean this
"来电显示"
For full example please click here.
I don't know what is the "" used for? Because if I remove the "" beside the string value (e.g. "来电显示" change to 来电显示), the output won't change any more, both "来电显示" and 来电显示 will print 来电显示 as the output.
So does the quotations make any sense here?

It makes sense on languages that are using simple quotes '.
If simple quotes aren't escaped like this, \', Lint will detect an error.
Using double quotes at the start and at the end of a string value will allow you to omit these backslashes.
There may be other purposes I didn't discovered yet.

How to use escape characters in XML

How can I use escape characters in XML?
The situation is, I am a new android developer, and I need a string which need to be printed in 2 lines (other wise no space). This string is in string.xml file. I need to use /n line break character to break the string, but I don't know how to do it in XML file. Please help.

See reference http://developer.android.com/guide/topics/resources/string-resource.html#String
line break symbol is \n
/n - is wrong.
and you can write it in xml like it is.
Example:
<string name="multiline_text">line 1.\nline2.</string>

I'm not familiar with Android development but have you checked out CDATA? Refer to this link.
Basically, you wrap your string value like so:
<![CDATA[string value]]>

You can use double quotes:
<string name="mystring">"One line\nAnother line"</string>

You can use the character entity
to indicate a linefeed.

Android Replace "..." with ellipsis character

Since AVD tools 16 I'm getting this warning:
Replace "..." with ellipsis character (..., …) ?
in my strings.xml
at this line
<string name="searching">Searching...</string>
How do I replace ...? Is it just literally …?
Could someone explain this encoding?

… is the unicode for "…" so just replace it. It's better to have it as one char/symbol than three dots.

To make thing short just put … in place ...
Link to XML character Entities List
Look at Unicode column of HTML for row named hellip

If you're using Eclipse then you can always do the following:
Right click on the warning
Select "Quick Fix" (shortcut is Ctrl + 1 by default)
Select "Replace with suggested characters"
This should replace your three dots with the proper Unicode character for ellipsis.
Just a note: The latest version of ADT (21.1) sometimes won't do the replace operation properly, but earlier versions had no problem doing this.
This is the character: …

The solution to your problem is:
Go to Window -> Preferences -> Android -> Lint Error Checking
And search for "ellipsis". Change the warning level to "Info" or "Ignore".

This answer is indirectly related to this question:
In my case textView1.setTextView("done&#8230"); was showing some box/chinese character. Later, I checked into fileformat.info for what the value represents and I found this is a Han character.
So, what to do? I searched for "fileformat.info ellipse character" and then everything became clear to me once I saw its values are;
UTF-16 (hex) 0x2026 (2026)
UTF-16 (decimal) 8,230
So, you have several encoding available to represent a character (e.g. 10 in Decimal is represented as A in hexa) so it is very important to know when you are writing an unicode character, how receiving function decodes it. If it decodes as decimal value then you have to provide decimal value, if it accept hexadecimal then you have to provide hexadecimal.
In my case, setTextView() function accepts decimal encoded value but I was providing hexadecimal values so I was getting wrong character.

The quick fix shortcut in Android Studio is Alt + Enter by default.

Best not to ignore it as suggested by some, it seems to me. Use Android Studio to correct it (rather than actually typing in the character code), and the tool will replace the three dots with the three-dot unicode character. Won't be confusing to translators etc.
