Need "tolower" here, as "isxdigit" allows upper and lowercase letters.

Fixed!

Use the same code for IPP_TAG_NAMELANG and IPP_TAG_TEXTLANG (with the two case statements together feeding into the same code).

Don't you need to read another token here?

Hi!
For input like "my string"(language), the var, value, at line 695, initially contains 'my string' , which then is fed into string.text.
Next a token i.e. (language) is read into var value at line 696, which then is fed into string.language.
I don't think another token needs to be read here, is it ?

report_error(f, v, user_data, "Bad Language Value in line %d of \"%s\".", f->linenum, f->filename);
return (0);
