    <car><make>Ford</make><model>Mustang</model><year>1998</year></car>
    <car><make>Mercedes</make><model>C-Class</model><year>1999</year></car>
    <car><make>Mercedes</make><model>C-Class</model><year>2009</year></car>
</cars>

Q2. You are working with the following XSD fragment. What does it say about the <car> element?

<xs:element name="car">
    <xs:complexType>
        <xs:sequence>
            <xs:element name="make" type="xs:string"/>
            <xs:element name="model" type="xs:string"/>
            <xs:element name="year" type="xs:string"/>

Q3. You are converting your HTML file into XHTML Strict. Which code snippet will validate without errors?

Q4. When working with Ajax applications, which is faster, XML or JSON?

Q5. Asynchronous Javascript and XML (Ajax) is technique for creating better, faster, and more interactive web applications. In addition to JavaScript and XML on the back end, which technologies are commonly used to craft AJAX experiences on the front end?

Q6. What is this code an example of?

<x/>

Q7. Which XHTML syntax rule does NOT apply to XML?

Explanation: XML Attributes values must be quoted. Element names are case-sensitive (and CamelCase is actually one of the naming styles).

Q8. Which Ajax method is used to exchange data with a server, using a modern browser?

Q9. A markup language is a _ -readable language that _ text so that the computer can _ that text.

Q10. What is this code an example of?

<x a="x" a="y"></x>

Q11. XML provides a framework for specifying markup languages, while HTML is a predefined markup language. What is applicable to XML and not HTML?

Q12. What is the last step in extending XHTML modules?

Q15. You are working with an XML document that uses an XML schema. How do you specify that an element can appear multiple times inside its parent element?

Q16. The <xsl:with-param> element defines the value of a parameter to be passed into a template. It can be used within which elements?

Q17. You are checking someone else’s XML document for errors. You notice that the prolog does not have a closing tag. What do you do?

Q18. Which statement is not true about XML?

Q19. In an XML DTD ATTLIST declaration, which tokenized attribute type is used to specify multiple ID values?

Q20. You want to convert a large XML file into CSV format. You did not create the XML file, so you are not familiar with all of the syntax. What will help you get the best insight into the file contents?

This question is about understanding the XML аfile contents. XSD is the correct one here - that's the schema document, which describes the XML.

Q21. In an XML DTD, attributes are declared with an ATTLIST declaration. You need to validate the color attribute for element <car> against a fixed list of values. Which is the correct declaration?

Q22. The main ways to control the display of XML documents are with Cascading Style Sheets (CSS) and Extensible Styles Language (XSL). What is an advantage of CSS over XSL?

Q23. Which type of DTD declaration is this code an example of? <!DOCTYPE abc SYSTEM "file/file.dtd">

Q24. The purpose of an XML schema is to define the building blocks of an XML document. Which option best describes the building blocks of an XML document?

Q25. An XHTML document type definition (DTD) describes the allowed syntax and grammar of XHTML markup. Which is not one of the formal DTDs used in XHTML 1.0?

Explanation: XHTML - Doctypes

Q26. You are working with the following XML code snippet. You have this line in your XSLT code xsl:value-of-select="//car/make"/>. What does it display?

<cars>
    <car>
        <make>Cadillac
            <model>Escalade</model>
            <price year="2007">$20,000</price>
        </make>
    </car>
</cars>

Q27. You need to display the list of cars in the code snippet below in a column format, with a counter column for each row. Which XPath function do you use for the counter?

<cars>
    <car><make>Cadillac</make> <model>Escalade</model> <year>2007</year></car>
    <car><make>Ford</make> <model>Mustang</model> <year>1968</year></car>
    <car><make>Mercedes</make> <model>C-Class</model> <year>1999</year></car>
</cars>

Explanation: count() returns the total the number of nodes (3), while position() returns the 0-based index of each node.

Q28. You are working with this XML code snippet from the XML document cars.xml. You need to return the information about the cars built after the year 2000, as an ordered list, starting with the most recent. What does your XQuery look like?

<cars>
    <car><make>Cadillac</make> <model>Escalade</model ><year>2007</year></car>
    <car><make>Cadillac</make> <model>Escalade</model> <year>2011</year></car>
    <car><make>Ford</make> <model>Mustang</model> <year>1968</year></car>
    <car><make>Ford</make> <model>Mustang</model> <year>1998</year></car>
    <car><make>Mercedes</make> <model>C-Class</model> <year>1999</year></car>
    <car><make>Mercedes</make> <model>C-Class</model> <year>2009</year></car>
</cars>
<ul>
{
    for $x in doc("cars.xml")/cars/car
    where $x/year>2000
    order by $x/year descending
    return <li>{$x}</li>
}
</ul>
<ol>
{
    for $x in doc("cars.xml")/cars/car
    where $x/year>2000
    order by $x/year desc
    return <li>{data($x)}</li>
}
</ol>
<ul>
{
    for $x in doc("cars.xml")/cars/car
    where $x/year>2000
    order by $x/year
    return <li>{$x}</li>
}
</ul>
<ol>
{
    for $x in doc("cars.xml")/cars/car
    where $x/year>2000
    order by $x/year descending
    return <li>{data($x)}</li>
}
</ol>

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>

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.
