Dynamic arguments to a Logicsheet?

[Jonathan Stimmel <js...@taos.com>]

I've finally begun ot play with logicsheets over the past couple
weeks, and for the most part they've worked as I expected.

One thing I can't see how to do is to pass dynamic data to a custom
tag. I can do:
  <ns:myTag param="value"/>
but not:
  <ns:myTag>
    <xsp:attribute name="param">
      <request:get-parameter name="param"/>
    </xsp:attribute>
  </ns:myTag>

Also, my logicsheet is just a wrapper around the sql taglib, however
I have to add "xmlns:sql='http://www.apache.org/1999/SQL' to both the
logicsheet and xsp page (the latter shouldn't need to know about the
implementation of the taglib, IMO).

Are these actual limitations, or am I just missing something obvious?

Ok, I've almost got this working, thanks to some documentation in the
cocoon2 source branch. The catch is that you must use child nodes
to pass dynamic data:
  <ns:myTag>
    <ns:param><request:get-parameter name="param"/></ns:param>
  </ns:myTag>
However, I now have the following ugly code in my logicsheet:
  <sql:query>
    <xsl:text>SELECT * FROM Table</xsl:text>
    <xsl:text> WHERE Column=" +</xsl:text>
    <xsl:call-template name="get-nested-string">
      <xsl:with-param name="content" select="dir:category"/>
    </xsl:call-template>
    <xsl:text>+ "</xsl:text>
  </sql:query>
I borrowed get-nested-string from the sql logicsheet. Note the '" +'
and '+ "' I had to add to get the generated code correct. The <xsl:text>
nodes are also rather annoying; without them, I had to place the entire
query on a single line.

In XSL you would do:

<xsl:element name="ns:myTag">
<xsl:attribute name="param"> ...

I don't know if XSP also has a <xsp:element> thing, you should check it
out.
