Hello!!

I have a XML with an element named Question. I also have a XSL looking like this:

Code:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl"
>

    <xsl:template match="@* | node()">
		<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
			<fo:layout-master-set>
				<fo:simple-page-master master-name="Letter" page-height="11in" page-width="8.5in">
					<fo:region-body region-name="only_region" margin="1in" background-color="#CCCCCC"/>
				</fo:simple-page-master>
			</fo:layout-master-set>
			<fo:page-sequence master-reference="Letter">
				<fo:flow flow-name="only_region">
					<fo:block text-align="center">???</fo:block>
				</fo:flow>
			</fo:page-sequence>
		</fo:root>
    </xsl:template>
</xsl:stylesheet>
In the fo:block I would like to get the value in element Question from the XML. How do I do this?
