Do i need to learn asp
No, you don't need to learn asp to use XML. asp and VBScript is yet another way to process XML. XML suppoprt is available in a wide spectrum of languages - Java, JavaScript, SmallTalk, Perl, Python, C, C++, ADA, Pascal .... and so on.
Checkout the XML tools section on IBM Developerworks site for a comprehensive list of XML parsers. Ofcourse, if you choose to go with a parser from Microsoft( called MSXML ), then you are better off learning VBScript and ASP. Checkout the MSXML freebies on www.vbxml.com
What is the jaxp and xml4j parser
XML4J is a parser. XML parsers allow you to (ofcourse,) parse an XML document and report any errors. They also provide facilities to access different parts of an XML document. XML4J is a parser written in Java and is freely distributed by IBM. There are a lot of other parsers too, such as Crimson from Sun, Xerces-J from Apache and so on. ( see http://xml.apache.org for details ).
JAXP stands for Java API for XML Parsing. It is a set of classes that provide a layer of abstraction to the underlying parser. This way you can write client code that does not depend on a particular parser implementation. You will also be able to plug in any parser of your choice without affecting the clients. JAXP is a product of Sun and is being bundled with JDK1.4 as a core package. See http://java.sun.com/xml for details.
Whats their use and how do i implement it in xml stuff.
If you plan to use XML technology in your application(s), you will certainly need a parser. A parser will allow you to step through the document, make sure it is syntactically correct and structurally valid. A parser will then allow you to navigate the XML document so that you can read different parts, search for specific chunks of information, mutate the document, transform the document and generate formats in which it can be presented to the end client.
Assuming that you are already familiar with the basics of XML technology, the best way to get started is to download a parser. As I said before, you have a lot of options available. If you are comfortable with programming in Java, I recommend the Xerces-J parser from Apache(http://xml.apache.org/xerces-j) After installing the parser, checkout the sample programs.
Cheers!
