Parse Special Characters with parseSpecialCharacter
Certain characters must be encoded when included in HTML documents. Characters
such as greater than are encoded as
>
. Additionally you can encode ASCII codes. For
example ASCII character 34 could be encoded as
"
.
The
parseSpecialCharacter
function handles these character encodings.
This function begins by reading the first character and seeing if it is an ampersand (&). If the
first character is an ampersand then a
StringBuilder
object is setup to hold the rest
of the character encoding.
char ch = (char) source.read();
if (ch == '&')
{
StringBuilder buffer = new StringBuilder();
Next, a loop is started that will read the rest of the character encoding up to the semico-
lon that ends all character encoding.
do
{
ch = (char) source.read();
if (ch != '&' && ch != ';')
{
buffer.append(ch);
}
If a beginning tag less-than character is found, then the character encoding is invalid, so
we just return an ampersand. This is the best we can do with regards to decoding the char-
acter. The
do/while
loop will continue until a semicolon is found, or we reach the end of
the file.
if (ch == '<')
return '&';
} while (ch != ';' && (ch != -1));
