1) Where is xml used, and where can it be used?
Well, that's quite a question, xml is a platform and language independent, which means it doent matter that computer may be using(Solaris, unix, linux), XML is potential fit for exchange format. The following are just few example.
1)Reducing Server load.
2)Web site Content.
3)RPC(Remote procedure call).
4)E-Commerce.
2) Illegal PCDATA Character
They are some reserverd character that you cant include in your PCDATA(Parsed Character Data) because they are used in xml syntax. The below characters are reserved word in xml.
1) &
2) <
3) >
4) '
5) ""
They are two ways you can get around this,
1) Escaping characters.
2)Enclosing tag with CDATA Sections.
1)Escaping Characters.
& -- amp;
<--lt;
2)Enclosing tag with CDATA Sections.
if you have lot of "<" and ">" that you need to cdata.
<test><![cdata[<is<7&7>7]]></test>
Output
<is<7&7>7
