Re: Re: Keeping a running total?

<xsl:when test="count(preceding-sibling::factory/@widget) > $limit">

Failing that, come up with a concise input XML and give an example of
the required output XML.  Your original question was a bit wordy...

<xml>
   <factory x="A" capacity="2">
   <factory x="B" capacity="1">
   <factory x="C" capacity="2">
   <factory x="D" capacity="1">
   <factory x="E" capacity="2">
</xml>
