[xsl] RE: [xsl] Re: [xsl] Handling of special characters like © etc

["Yogesh Dare" <yogeshd at cybage dot com>]

Hi Mike,
thanx for the detailed mail.
One more favour now.
I will be speaking abt second part of my mail i.e.& and < (and >, for
balance)  etc.
Here I want to escape thr' < and > characters when it representd node
i.e.<root> and suppose this appears as a part of text like this
<mail-sender><mike@skew.org></mail-sender> then only I want to get rid of <
and > characters.
How to differentiate this before sending it to XSLTProcessor.

Thanks,
Yogesh

Encoding is, roughly, the mapping of a repertoire of abstract characters
(units in a script for written language) to 1 or more code units (bytes,
usually). Your XML file exists with some kind of encoding, because it is,
after all, just a bunch of bits & bytes.

The encoding declaration in an XML document (the encoding="foo" part of
the <?xml ...?> line at the top) is an XML document's way of stating what
encoding it has. When you omit the encoding declaration, either UTF-8 or
UTF-16 are assumed, usually UTF-8.

The copyright symbol is allowed in XML, but since you have implied that
your document is probably UTF-8 encoded, that symbol must be encoded as
the pair of bytes 0xC2 0xA9.

If this is giving you problems, then your file is not really UTF-8
encoded, and this is an error. Chances are, it is encoded as just the byte
0xA9, because your file was produced with iso-8859-1 or windows-1252
encoding. You should get a text editor that saves in different encodings,
rather than just your platform/OS default, and that has a hex mode so you
can see the actual bytes in the file. I use TextPad, from
http://www.textpad.com/

If you don't want to put the correct bytes in your file, you can either
correctly declare the encoding as iso-8859-1 or windows-1252, or you can
use &#169; or &#xA9; in your XML and XSLT documents, rather than the raw
characters.

& and < (and >, for balance) are XML markup characters. If you are using
them as character data, you must either escape them, or put them in a
CDATA section, if one is allowed there. This is a requirement of all XML
documents, including your source XML and the stylesheet.
