Assume the use of XML Data like [XML Data] referenced in a separate window.

When a data element is present in XML Data, there are three possibilities for b element as shown in [XML Data b Element] (separate window). No other possibilities are available.

Consider inserting any XML data into an XMLDB using the methods shown in [Operation 1] or [Operation 2].

Select the correct answer that allows for a clear identification of the three different possibilities for [XML Data b Element].

[Operation 1]

After validating against the following [XML Schema], insert XML data (having no validation errors) into the XMLDB.

When no b element is present, the b element value is null.

When b element is present, the b element value is either 1 or 2 in [XML Data b Element].

[Operation 2]

After validating against the following [DTD], insert XML data (having no validation errors) into the XMLDB (do not consider the existence of a document type declaration in the XML data).

When the b element value is "null", the value of the b element is null.

When the b element value is a character string other than "null", the b element value is 1 in [XML Data b Element].

When the b element is an empty element, the b element value is 2 in [XML Data b Element].

[DTD]

See separate window.

Assume you wish to execute a query on [example xml] (separate window) to obtain a record element that includes a data element for which the condition attribute value is "good," and for which the element value is 100 or less.

Select the correct result of executing the [XQuery] (separate window). The expected result would be "C;" however, the query may not be processed as expected.

Select the correct result of executing the [XQuery] on [example xml] referenced in a separate window. Do not consider indents (ignorable white space such as line feeds, tabs, etc.) in [example.xml] or the execution results.
