Re: [xsl] Unwanted Empty Elements from transformation

[Joerg Heinicke <joerg.heinicke@xxxxxx>]

Hello,

you have a few Foundation.Core.Class elements in your XMI (?) file, that 
don't have Foundation.Core.ModelElement.name elements as childs, so the 
<xsl:value-of select="Foundation.Core.ModelElement.name"/> returns an 
empty string.

You can either change you <xsl:apply-templates/> to

<xsl:apply-templates 
select="//Foundation.Core.Class[Foundation.Core.ModelElement.name]"/>

or add a predicate to the template matcher

<xsl:template 
match="Foundation.Core.Class[Foundation.Core.ModelElement.name]">

Regards,

Joerg
