New StringUtils library

[Erel]

This library supports Base64 encoding / decoding, URL format encoding and also it includes the beloved LoadCSV and SaveCSV methods.

Reference: Basic4android - StringUtils
The table example was updated and it can now load and save tables with these methods.

Nice one. Many thanks...

If your open to a suggestion, how about including delimited string functionality? It would be nice to have the ability to get the count of sub-strings, extract an individual sub-string (at a specific position), add a sub-string, replace a sub-string, remove a sub-string, find a sub-string and return it's position, split a delimited string into an array, join array elements into a delimited string, and set the delimiter char. Some of this functionality may exist already..

Thanks...

You can achieve most or all of these features with the internal String and Regex methods.

Erel,

would it be possible to extend this library by adding support for the StringEscapeUtils-library? If I understand it correctly, you would need to add this library and your relative wrapper-code with your library.

See this post:
java - How can I Decode string? - Stack Overflow

and this is the library:
StringEscapeUtils (Commons Lang 2.5 API)

Personally, I am particularly interested in escaping/unescaping HTML and XML.

I didn't want to include the Apache Commons library in StringUtils to avoid adding the Apache license.

Did you try to use UrlEncode / Decode? It should be similar to XML encoding / decoding.

Yes, I tried URLEncode/Decode but it will not work. For XML it is not really a problem - I believe using the XML-parser will take care of the entities.

The problem is more the HTML-entities (after getting a HTML-source) and showing the output correctly when working with strings.

I will try to write my own wrapper-library and see how it goes. If I get stuck with the library, I guess I can simply write a code-module with all HTML-entities and their corresponding character-values (such as :

Thanks anyway.

Can you post an example of an encoded string and the decoded string?

In this moment I can't connect to the source of the html-page but what happens is that I use a procedure similar to this one to download the html-source for successive parsing:

Dim Reader As TextReader
reader.Initialize(HttpUtils.GetInputStream(posturl))

ChannelList.Initialize

Dim line As String
line = Reader.ReadLine

Do While line <> Null  
if line <> Null Then        
ChannelList.Add(line)
End If
line = Reader.ReadLine
Loop
Reader.Close

For i = 0 To channelList.Size -1
channelCode=channelList.Get(i)
'various code for parsing channelcode
loop

TextReader supports UTF8 encoding by default which should be OK. I know that I can use reader.Initialize2 and specify which encoding to use but I doubt this will help because in any case, I don't know beforehand which encoding-scheme is being used.

In any case, using above code, for instance I get:

PHP Code:

------->> Generalisti <<------- 


which should be:

PHP Code:

------->> Generalisti <<------- 


Of course, the string parsed may contain other HTML-entities.

That is why I thought something to handle the HTML-entities could be useful.
