[newbie] Parsing UTF-8 unicode XML file

[joahim]

Hi,

I'm trying to write a simple program for parsing [UTF-8] XML files.
The built-in XML library has some license restrictions, so I decided to read the file step by step, using the command ReadUnicodeCharacter.

Code: Select all

If OpenFile(1,"document.xml")
  While Eof(1) = 0
  something = ReadUnicodeCharacter(1)
  ...  
  Wend  

EndIf

1. How can I create a string from unicode characters read in this way?
2. How can I compare unicode character with a string?

TIA,

joahim

Hi,

you should read the file like this:

Code: Select all

File = OpenFile(#PB_Any,"document.xml")
If File
  ReadStringFormat(File)  ; to skip a BOM if available
  While Not Eof(File)
    Line$ = ReadString(File, #PB_UTF8)
    Debug Line$
  Wend 
  CloseFile(File)
EndIf

Than you can use the 'normal' string functions like FindString().

ReadStringFormat?

Huh, the XML file contains no EOL character, so the string would have > 1 MB.

Any ideas?

Do you have more than 4MB RAM

Than you'll have no problem

Oh, maybe the Debug takes a bit...

You can also do this:

Code: Select all

File = OpenFile(#PB_Any,"document.xml")
If File
  ReadStringFormat(File)  ; to skip a BOM if available
  While Not Eof(File)
    Line$ + ReadString(File, #PB_UTF8)
  Wend
  Debug Line$
  CloseFile(File)
EndIf

So you can be sure that always everything is in Line$.

Just wondering, which license restriction is bothering you ?

I cannot see any restrictions?

Sounds like at most you just have to acknowledge your used the parser in your ReadMe file / documentation, and display the appropriate copyright attributions.
I don't see a problem with this. I'm planning on using it in my Text RPG Engine.
