Q33. You are working with the following XML code snippet. What do you need to include in your XSLT code to display Mercedes, Cadillac, Ford?

<cars>
    <car><make>Cadillac</make><model>Escalade</model>
        <price year="2007">20000</price></car>
    <car><make>Ford</make><model>Mustang</model>
        <price year="2008">17000</price></car>
    <car><make>Mercedes</make><model>C-Class</model>
        <price year="2009">24000</price></car>
</cars>
  •  <xsl:sort select="make" />
  •  <xsl:sort select="model" />
  •  <xsl:sort select="car" />
  •  <xsl:sort select="price" />

Explanation: A trick question. The <xsl:sort> will sort the output in ascending (alphabetical for strings) order by default. The select tells which tag to use for sorting.

  • If we use select="make" or select="year" we get the order Cadillac, Ford, Mercedes
  • If we use select="price" we get Ford, Cadillac, Mercedes
  • And finally with select="model" we get Mercedes, Cadillac, Ford

Q36. XHTML modules can be extended by adding elements, attributes, modifying content models, or some combination of these. What does a proper implementation of an XHTML module require?

  •  The implementation of an XHTML module requires a definitions module and a constraint module that specifies syntax rules and uses the parameter entities declared in the definitions module.
  •  The implementation of an XHTML module requires a qualified name module and a declaration module that holds the element, element attribute, and content model declarations.
  •  The implementation of an XHTML module requires a namespace module that holds the element, element attribute, and content model declarations, and a parameter module that uses the entities declared in the namespace module.

Q37. The <xsl:namespace-alias> element is used to replace a namespace in the style sheet with a different namespace in the output. Which XSLT element needs to be its parent node?

  •  <xsl:namespace>
  •  any valid element
  •  root element
  •  top-level element in the corresponding namespace

reference link:

Q38. XML is a markup language, not a programming language. What makes XML not qualify to be a programming language?

  •  XML is too flexible and does not have enough reserved keywords.
  •  XML contains only data and not any processing instructions.
  •  XML does not perform any computation or algorithms.
  •  XML does not have specialized syntax rules.

Q39. What is true about these elements in XQuery?
