Pulling Internal note to a label

I am trying to pull the internal note to the shipping label. Right now we are able to pull the invoice number to the label, but i would like to include the internal note right above that. This is the code I have right now that pull the invoice number 

Invoice #: <xsl:value-of select="//Order/Number" /><br></br>

I have done some forum search and created this code which is pulling the internal note but it also includes a bunch of unneeded information 

Order #: <xsl:value-of select="//Note[Visibility='Internal']" />
Invoice #: <xsl:value-of select="//Order/Number" /><br></br>

I would like it to say

Order # XXX-XXXXXXX-XXXXXXX
Invoice # XXXXXXX

Any ideas?? Thank you
