XML Interview Questions & Answers - Learning Mode

Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. Extensible Markup Language (XML) is used to describe data. The XML standard is a flexible way to create information formats and electronically share structured data via the public Internet, as well as via corporate networks. XML is a way of adding intelligence to your documents. It lets you identify each element using meaningful tags and it lets you add information ("metatdata") about that element.

Question: Some Limitation or Disadvantage of XML?

Answer: XML markup has a few disadvantages:
It can be verbose unless element and attribute names are chosen with care. In large documents the markup overhead need not be large, but in short messages it can be significantly more than the actual data, especially when the element or attribute names are concocted by machine.
Overlapping markup is not permitted (an element cannot start inside one element and end inside another): element markup must nest hierarchically.
Question: Is XML case-sensitive?

Answer: Yes. Source:
Question: What is Document Type Definition (DDT) in case of XML?

Question: Explain brifely about XML Template?

Question: Why is XML such an important development?

Answer: It removes two constraints which were holding back Web developments:
1. dependence on a single, inflexible document type (HTML) which was being much abused for tasks it was never designed for;
2. the complexity of full SGML, whose syntax allows many powerful but hard-to-program options.
XML allows the flexible development of user-defined document types. It provides a robust, non-proprietary, persistent, and verifiable file format for the storage and transmission of text and data both on Source:
Question: What are XML indexes and secondary XML indexes?

Question: How does XML handle white-space in my documents?

Answer: All white-space, including linebreaks, TAB characters, and normal spaces, even between ?structural? elements where no text can ever appear, is passed by the parser unchanged to the application (browser, formatter, viewer, converter, etc), identifying the context in which the white-space was found (element content, data content, or mixed content, if this information is available to the parser, eg from a DTD or Schema). This means it is the application's responsibility to decide what to do wit Source:
Question: Describe about the syntax rules which form the XML documents?

Answer: Some of the basic syntax rules which are to be implemented are
1) XML documents should have a root element
2) They should have a closing tag
3) Make sure that you type exact case, as these documents are case sensitive.
4) These elements should be properly nested
5) Attribute elements must be quoted correctly. Source:
Question: Explain about XML Canonicalization?

Answer: Often it happens that documents are identical in many different ways either logical of statistical. It becomes a major problem when you try to sign a digital signature on two identical documents, to eliminate this problem you have to use Canonicalization which helps people in identifying two similar documents with similar digital signature. Similar documents use Canonicalization to identify similar patterns and signature. Source:
Question: What is DOM?

Answer: DOM is an interface-oriented Application Programming Interface. It allows for navigation of the entire document. Source:
Question: Give a few examples of types of applications that can benefit from using XML.

Answer: There are literally thousands of applications that can benefit from XML technologies. The point of this question is not to have the candidate rattle off a laundry list of projects that they have worked on, but, rather, to allow the candidate to explain the rationale for choosing XML by citing a few real world examples. For instance, one appropriate answer is that XML allows content management systems to store documents independently of their format, which thereby reduces data redundancy. Another Source:
Question: Is there a way to describe XML data?

Answer: Yes, XML uses Document Type Definition (DTD) to describe the data. Source:
Question: When constructing an XML DTD, how do you create an external entity reference in an attribute value?

Answer: Every interview session should have at least one trick question. Although possible when using SGML, XML DTDs don't support defining external entity references in attribute values. It's more important for the candidate to respond to this question in a logical way than than the candidate know the somewhat obscure answer. Source:

Answer: authentication, message integrity, and non-repudiation. In addition to signature information, an XML Signature can also contain information describing the key used to sign the content. Source:
Question: Explain about XML namespaces?

Answer: Namespaces are guided by the guidelines of w3c. These are used to uniquely identify the named elements and attributes of an XML document. As XML supports human interpreted language and structure it is necessary for namespaces to differentiate different elements present in an XML document. It is declared using XML attribute xmlns and the value of it should be Uniform resource identifier. Source:
Question: What is DOM?

Answer: Document Object Model (DOM) is a W3C specification that defines a standard (abstract) programming API to build, navigate and update XML documents. It is a ?tree-structure-based? interface. As per the DOM specification, the XML parsers (such as MSXML or Xerces), load the entire XML document into memory, before it can be processed. XPath is used to navigate randomly in the document, and various DOM methods are used to create and update (add elements, delete elements, add/remove attributes, etc.) t Source:
