Yes, provided you use up-to-date SGML software which knows about the WebSGML Adaptations TC to ISO 8879 (the features needed to support XML, such as the variant form for EMPTY elements; some aspects of the SGML Declaration such as NAMECASE GENERAL NO; multiple attribute token list declarations, etc).
An alternative is to use an SGML DTD to let you create a fully-normalised SGML file, but one which does not use empty elements; and then remove the DocType Declaration so it becomes a well-formed DTDless XML file. Most SGML tools now handle XML files well, and provide an option switch between the two standards.

Yes, the W3C recommends using XHTML which is ‘a reformulation of HTML 4 in XML 1.0’. This specification defines HTML as an XML application, and provides three DTDs corresponding to the ones defined by HTML 4.* (Strict, Transitional, and Frameset).
The semantics of the elements and their attributes are as defined in the W3C Recommendation for HTML 4. These semantics provide the foundation for future extensibility of XHTML. Compatibility with existing HTML browsers is possible by following a small set of guidelines

No, although it's useful because a lot of XML terminology and practice derives from two decades'experience of SGML. Be aware that ‘knowing HTML’ is not the same as ‘understanding SGML’. Although HTML was written as an SGML application, browsers ignore most of it (which is why so many useful things don't work), so just because something is done a certain way in HTML browsers does not mean it's correct, least of all in XML.

Successful candidates should recognize this as one of the most basic applications of XSLT. If they are not able to construct a reply similar to the example below, they should at least be able to identify the components necessary for this operation: xsl:template to match the appropriate XML element, xsl:value-of to select the attribute value, and the optional xsl:apply-templates to continue processing the document.
Extract Attributes from XML Data
Example 1.
<xsl:template match="element-name">
Attribute Value:
<xsl:value-of select="@attribute"/>
<xsl:apply-templates/>
</xsl:template>

Although XML does not require data to be validated against a DTD, many of the benefits of using the technology are derived from being able to validate XML documents against business or technical architecture rules. Polling for the list of DTDs that developers have worked with provides insight to their general exposure to the technology. The ideal candidate will have knowledge of several of the commonly used DTDs such as FpML, DocBook, HRML, and RDF, as well as experience designing a custom DTD for a particular project where no standard existed.

Superficially, this is a fairly basic question. However, the point is not to determine whether candidates understand the concept of a parser but rather have them walk through the process of parsing XML documents step-by-step. Determining whether a non-validating or validating parser is needed, choosing the appropriate parser, and handling errors are all important aspects to this process that should be included in the candidate's response.

Tree-based API: It compiles and loads an XML document into the memory in a tree-like structure. You may traverse the tree structure, and alter it. Tree-based API's are useful for a wide range of uses. DOM parser is an example of a Tree-based API.
Event-based API: An event-based API delivers the information surrounding the parsing case to an application. This requires an integrated collection of callback features. SAX parser is an example of event-based API.

XML data binding refers to the reading and writing of XML data using a programming language. XML data binding usually occurs using a class library (like C++, Java ), specifically for the given XML data format.
With XML data binding, applications can directly access the required data with the XML file’s created APIs instead of relying on the Document Object Model (DOM) to retrieve the data from the XML file.

HTML was already overburdened with dozens of interesting but incompatible inventions from different manufacturers, because it provides only one way of describing your information.
XML allows groups of people or organizations to question C.13, create their own customized markup applications for exchanging information in their domain (music, chemistry, electronics, hill-walking, finance, surfing, petroleum geology, linguistics, cooking, knitting, stellar cartography, history, engineering, rabbit-keeping, question C.19, mathematics, genealogy, etc).
HTML is now well beyond the limit of its usefulness as a way of describing information, and while it will continue to play an important role for the content it currently represents, many new applications require a more robust and flexible infrastructure.

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 answer relates to B2B exchanges or supply chain management systems. In these instances, XML provides a mechanism for multiple companies to exchange data according to an agreed upon set of rules. A third common response involves wireless applications that require WML to render data on hand held devices.

XML editors allow building an error-proof XML document which is then validated against either of the two i.e. Schema or DTD. There are several reasons to use XML editors because they can check both open and closed tags, they can validate against DTD and Schema. The editor can also check the color code on a syntax of XML.

When working with XML documents, it is important to understand the rules of the language to ensure that any code created is correct and functional. An interviewer will often ask prospective employees to explain the key principals and requirements of languages they will be using. Although you do not need to offer an in-depth breakdown of every rule and industry standard for working with XML, you should note all of the key rules that any coder would be expected to know and understand.

Simple elements in XML are items based on a text. It has less attributes, less child elements and can not be left empty.
Complex elements can therefore hold multiple attributes and elements. It can also include additional sub-elements and empty-element.

All you see in an XML document is XML element, from the start tag to the end tag. This may be comprised of other elements, attributes and texts.
An Attribute is a definition used to define additional element detail.
Let's take an example to understand it well:
<librarymembers>
<student id="1">
<name>suresh</name>
<age>45</age>
</student>
</librarymembers>
In the above example, <student> is an element and id is an attribute of the <student> element.

XSL stands for the language of Extensible Stylesheets. It is a language used to express stylesheets. Such stylesheets are identical to CSS, which specifies how to view a given type of XML document.
>> DTD stands for description of document type while XSD stands for definition of XML schema.
>> The DTD allows no namespaces. To define a schema, it has its own set of keywords while XSD uses its own set of namespaces and elements to define the schema.
>> DTD is the predecessor to XML schema because XML schema is a new technology, it is not yet supported by any XML parsers.

A syntactically formed XML document is considered a syntactically correct document. Does the XML need to follow a well defined XML document? Simple syntax rules:
1. This needs to have a tag that locks.
2. The closing tag will match the open tag with precision: XML is case sensitive.
3. All components are to be used in one root tag.
4. Child components under parent tag must be closed.

Simplicity:The knowledge stored in XML is really simple to read and understand.
Openness:It is a W3C standard which is endorsed by market leaders in the software industry.
Extensibility: Extensible because it doesn't have a fixed set of tags. You can describe them however you like.
Self-descriptive: XML documents do not require unique schema configurations to store data like traditional databases. Without these concepts XML documents may be processed as they include metadata in the form of tags and attributes.
Scalable: XML is not in binary format so that you can create and edit files with anything, and debugger is easy too.
Fast access: XML documents are hierarchically arranged and it's comparatively easier.

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, nonproprietary, persistent, and verifiable file format for the storage and transmission of text and data both on and off the Web; and it removes the more complex options of SGML, making it easier to program for.

A markup language is a set of words and symbols for describing the identity of pieces of a document (for example ‘this is a paragraph’, ‘this is a heading’, ‘this is a list’, ‘this is the caption of this figure’, etc). Programs can use this with a style sheet to create output for screen, print, audio, video, Braille, etc.
Some markup languages (e.g. those used in word processors) only describe appearances (‘this is italics’, ‘this is bold’), but this method can only be used for display, and is not normally re-usable for anything else.

XML is the Extensible Markup Language. It improves the functionality of the Web by letting you identify your information in a more accurate, flexible, and adaptable way.
It is extensible because it is not a fixed format like HTML (which is a single, predefined markup language). Instead, XML is actually a metalanguage—a language for describing other languages— which lets you design your own markup languages for limitless different types of documents. XML can do this because it's written in SGML, the international standard metalanguage for text document markup (ISO 8879).
