RE: XSL with namespace from NVD

Hello,

You need to stay within the context of the matched b:entry
element; modify your stylesheet thusly:

  <xsl:template match="b:entry">
    <div>
      <xsl:number format="1."/>
      <xsl:value-of select="@name"/>
      <xsl:text> : </xsl:text>
      <xsl:value-of select="@CVSS_base_score"/>
    </div>
  </xsl:template>

and you will get what you want.

Regards,
EB
