XSLT: escaping double quote

Question

I have XSLT code like:

<xsl:if test="product_name='3" Magnifier'">
             <attribute name="Business Unit">
             Consumer
             </attribute>   
</xsl:if>

the value 3" Magnifier (has quote), I couldn't compare it with product name because of quote ambiguity. So how to escape double quote & resolve ambiguity.

Thanks.
