Hi,

	I have the following:
		<base version=""></base>

	When I do the following test:
		<xsl:if test="advertisement/source/base">
			<pickup-ref>
				<publication-ad-id>
					<xsl:apply-templates select="advertisement/source/base"/>
				</publication-ad-id>	
			</pickup-ref>
		</xsl:if>	

	I get the value of base.

	What I actualy want to test is if base has any text like 
<base version="">something here</base>. How can I do that?

TIA,
