[news.eclipse.birt.usability] XML dataset: how to define an XML dataset

[antoine.logean@xxxxxxxxxxxxxxxxx (Antoine)]

Hi everybody,

I use XML as data source. How can I define an xml data set that contains 
other data sets ?. As exemple (see below) I have a "DataSet_QCHistory" 
that contains many "ReviewRequests". This is the first level of my dataset 
(that is represented in a master table within the report). Now a 
"ReviewRequest" contains either many "Documents" and "Recommendations". 
This is the second level (a second table within the master table) of data 
sets that I would like to define.

	<DataSet_QCHistory>
		<ReviewRequest>   <-----------------------first level data set
			<sectionNumber>1</sectionNumber>
			<name>QC1</name>
			<dateOfReview>2007-12-31</dateOfReview>
			<Decision>Reworked</Decision>
			<Documents>   <------------------second level data set
				<externalLink>
					<title>QC1 Request Form</title>
				</externalLink>
				<externalLink>
					<title>GetCustomer policy</title>
				</externalLink>
			</Documents> 
			<Recommendations> <------------second level data set
				<recommendation>
					<content>Recommendation 1</content>
				</recommendation>
				<recommendation>
					<content>Recommendation 2</content>
				</recommendation>
				<recommendation>
					<content>Recommendation 3</content>
				</recommendation>
			</Recommendations>
			<QC2_mandatory>true</QC2_mandatory>
		</ReviewRequest>
		<ReviewRequest>
			<sectionNumber>1</sectionNumber>
			<name>QC1</name>
			<dateOfReview>2007-12-31</dateOfReview>
			<Decision>Reworked</Decision>
			<Documents>
				<externalLink>
					<title>QC1 Request Form</title>
				</externalLink>
				<externalLink>
					<title>GetCustomer policy </title>
				</externalLink>
			</Documents>
			<Recommendations>
				<recommendation>
					<content>Recommendation 1</content>
				</recommendation>
				<recommendation>
					<content>Recommendation 2</content>
				</recommendation>
				<recommendation>
					<content>Recommendation 3</content>
				</recommendation>
			</Recommendations>
			<QC2_mandatory>true</QC2_mandatory>
		</ReviewRequest>
	</DataSet_QCHistory>

Thank you very much for you help.
