The capture taglib won't solve this problem, because the captured
content can't be parameterized.
To achieve this, you can put the reused part in a method defined in a
<xsp:logic> block child of <xsp:page>. Below is an example, based on
simple.xsp form the samples.
<xsp:page
language="java"
xmlns:xsp="http://apache.org/xsp";
xmlns:xsp-request="http://apache.org/xsp/request/2.0";
xmlns:log="http://apache.org/xsp/log/2.0";
xmlns:capture="http://apache.org/cocoon/capture/1.0";
>
<xsp:logic>
private void reusedPart(String param) throws SAXException {
AttributesImpl xspAttr = new AttributesImpl();
<para>Hi there <xsp:expr>param</xsp:expr> ! I'm a simple dynamic
page generated by XSP (eXtensible Server Pages).</para>
<para>I was requested as the URI: <b><xsp-request:get-uri
as="xml"/></b></para>
}
</xsp:logic>
<page>
<log:logger name="xsp-sample" filename="xsp-sample.log"/>
<log:debug>Processing the beginning of the page</log:debug>
<title>A Simple XSP Page</title>
<content>
<capture:fragment-variable name="page_part">
<para>These 2 paragraphs were generated at the start of the XSP,
and captured for insertion at the end.</para>
<para>Brought to you by Cocoon2 at <xsp:expr>new
Date()</xsp:expr>.</para>
</capture:fragment-variable>
<xsp:logic>reusedPart("first time");</xsp:logic>
<xsp:logic>reusedPart("second time");</xsp:logic>
<para>The following list was dynamically generated:</para>
...
Hope this helps.
