Xml stands for extensible markup language. It is widely used for the representation of the various kinds of data structures. As an example you can take the web services. There are so many programming interfaces related to XML and you might be confused as well. An XML Specialist is a person who is an expert at XML and manages the whole XML coding.
Some of the interview questions which might be asked from you are as follows:
1. What is the full form of XML?
The full form of XML is extensible markup language.
2. What are the differences between SAX and DOM parser?
As far as the SAX is concerned, it parses node by node. It never stores the XML in the memory. However as far as the DOM is concerned it stores the whole XML into the memory before processing. It occupies more memory as well.
3. Suppose you want to search through a huge XML file. Then which parser will you prefer?
I would select DOM parser which is set as the default parser by Microsoft. I will select it because it is very robust as far as the traversing through huge XML file is concerned.
4. What procedure would you follow to create an XML file?
This is quite an easy job. You can do it with a simple text editor like notepad. You can use some other XML text editor as well. Just write the program and save it with .xml extension.
5. Name some other web services apart from XML.
Some of the other web services are Html, Cascading style sheet, JavaScript, DHTML, VBScript, asp and so on.
6. What do you know about the thread?
As far as the thread is concerned, it is the smallest set of instructions that can be executed.
7. What is the full form of DTD?
The full form of DTD is document type definition which is inherited from SGML.
8. Do you know something about Schematron?
It is the language to make the allegation about the presence of the known pattern in XML.
9. Do you feel that an XML can act as a data type?
Yes, it is now being extensively used as the first class data type.
10. Which edition is XML currently in?
XML is in the sixth edition at present. This edition was released in the year 2008.
11. What is the full form of W3C?
The full form of W3C is World Wide Web consortium.
These are some of the questions which can be asked from you when you will give the interview of the XML specialist. You will have to work very hard if you want to succeed in the interview round.
