You don't say whether the elements with "yes/no" flags can be nested, which
makes quite a difference to the solution. Assuming they can't, and that
you're only interested in the E elements, and that these all have the flag
present, I would write it as:

<xsl:template match="E[@flag='yes']">
<xsl:copy-of select="."/>
</xsl:template>

<xsl:template match="E[@flag='no']"/>
