Just to turn around your message:

I don't think so.  xsl:with-param is used to pass parameters into
templates.  Perhaps you meant xsl:param (to match the end tag you've got in
that template), but neither of these instructions will do anything about
adding things to your output, which I think is what you want.

>From what you've described, your input will look something like:

<fundgraph startDate="99-11-03" endDate="00-11-03" fundName="Technical">
  <fundvalue date="99-11-03" value="0.58" ordinal="0" />
  <fundvalue date="99-12-03" value="0.75" ordinal="0" />

and you want output might (complete guess here) look something like:

<object ...>
  <param name="startDate" value="99-11-03" />
  <param name="endDate" value="00-11-03" />
  <param name="title" value="Technical" />
  <param name="99-11-03" value="0.58" />
  <param name="99-12-03" value="0.75" />

The param elements that you're creating in the output are not the same as
the xsl:param elements that are used within XSLT to pass values into the
stylesheet or into templates.  The param elements in your output are in the
HTML namespace, whereas the xsl:param elements in the stylesheet are in the
XSLT namespace.

Just to start you off with the above example, you create elements within
your output either by using the xsl:element instruction:

  <xsl:element name="object">

or by literally putting the element in the result tree:


So, to create the above, you could have a stylesheet that looks like:

<!-- set the output method to HTML -->
<xsl:output method="html" indent="yes" />

<xsl:template match="fundgraph">
  <!-- create an object element -->
  <object ...>
    <!-- create the param elements from the fundgraph attribute values -->
    <param name="startDate" value="{@startDate}" />
    <param name="endDate" value="{@endDate}" />
    <param name="title" value="{@fundName}" />
    <!-- iterate over each of the fundvalue elements, 
         adding a param element for each              -->
    <xsl:for-each select="fundvalue">
      <param name="{@date}" value="{@value}" />

I hope that gets you started.  If not, feel free to post more details,
namely a sample bit of source XML and the output that you want to have
created from it.
