Title : Test142.XML 1.1 and Related Technologies


1. An Intranet Web application provides news for thousands of users inside one company. The application gets XML data from a database and then transforms the data into HTML with server-side XSLT.

A. Update the database to a higher version.
B. Use well formed XHTML tags in the application.
C. Supply the XML data and the stylesheet to Web browsers.
D. Use XSL-FO to make the transformation.
Answer: C

2. XML data is stored and retrieved within a relational database for a data-centric application by means of mapping XML schema elements to database tables. There are concerns that the queries and updates to this database are slow due to the number of joins required in the SQL. What is the best option for improving the storage and retrieval of this XML data?
A. Transform XML documents into canonical form before persisting.
B. Modify the current XML schema by converting elements to attributes where possible and re-map to tables in order to reduce the number of tables and therefore the number of joins required.
C. Store the XML data as CLOBs without decomposing them into relational tables and provide an 'id' based lookup.
D. Modify the current XML schema by merging all of the XML documents into a main XML document and query using XPath.
Answer: BD

3. The link element in the following XML fragment is the context node. Its target attribute is stored within the xsl:variable linkTarget. What XPath expression will find the page element whose id attribute value is described by the value of linkTarget?














A. ..//page[@id = $linkTarget]
B. ../../page[@id = '003']/page[@id = linkTarget]
C. //page[@id = $linkTarget]
D. ancestor::page/ancestor::page/child::page/child::page[id = $linkTarget]

B. When browsers request and customers order hard copies, render the XML data with CSS and then use the file for viewing and printing.
C. When browsers request, render the XML data with CSS. When customers order hard copies, transform the XML data with XSL-FO and then convert the file into PDF for printing.
D. When browsers request, render the XML data with XSL-FO and then convert the file into PDF for viewing. When customers order hard copies, transform the XML data with CSS and then use the file for printing.

Answer: C

6. Calculating sub-totals from an XML document using XSL transformation requires special considerations. Which of the following options is the best solution to solve this problem?
A. Create a fragment variable containing the values to total, and then use the node-set() XSLT extension and the XPath "sum()" function to calculate the value.
B. Create a special XSLT variable that contains the results of an XPath query that performs a "sum()" of the values to be totaled.
C. Use XSLT recursion to define a variable value that calculates the "value-of" the elements to be sub-totaled.
D. Use XSLTC to precompile a custom Java translet that will extract the values to be totaled and returns the sum of those values. This return value is then used in an XSL variable for output.
Answer: A
