[xsl] Assist With choose condition

["Scott Purcell" <spurcell at vertisinc dot com>]

Hello,
I am developing a xsl stylesheet. I need to check a condition and deal with it. Below is a snippet where I am building an img src tag. The problem is that the value in "contents" is sometimes empty. So I need to (on the commented out line) check if contents has a string in it. If it does, great, else I need to put in some default.jpg or something like that.

I have tried a couple of approaches, but with no luck.

This block is what I am trying to deal with. I don't know how to code if the block has data?
If someone could assist, I would be grateful.
Thanks,
Scott

<!-- test block to replace commented out line. -->
<xsl:choose>
   <xsl:if value-of select=''>
	default.jpg
   </xsl:if value-of select='hasdata'>
	<xsl:value-of select="contents" />
   </xsl:if>
</xsl:choose>




    <img height="100" width="100">
      <xsl:attribute name="src">
        <xsl:if test="type[.='system']">
            <xsl:value-of select="$systemimage" />
        </xsl:if>
        <xsl:if test="type[.='user']">
            <xsl:value-of select="$userimage" />
        </xsl:if>
        <xsl:if test="type[.='both']">
            <xsl:value-of select="$systemimage" />
        </xsl:if>
<!--       <xsl:value-of select="contents" /> -->
    </xsl:attribute>

    <xsl:attribute name="name">
        <xsl:value-of select="item_count" />
    </xsl:attribute>

    </img></center><br />
