OK I put chain module to cocoon.xconf
<component-instance
class="org.apache.cocoon.components.modules.input.JXPathMetaModule"
logger="core.modules.input.utils" name="jxpath">
<input-module name="chain"/>
<function name="java.lang.String" prefix="str"/>
<package name="java.util" prefix="util"/>
</component-instance>
in chain module is always string attribute "dn" ()
<component-instance
class="org.apache.cocoon.components.modules.input.ChainMetaModule"
logger="core.modules.input"
name="chain">
<input-module name="request-param"/>
<input-module name="request-attr"/>
<input-module name="session-attr"/>
<input-module name="defaults"/>
</component-instance>
so how can I access to length of the string in dn attribute ?
the example str:length(dn) do not work

Pls see javadocs for module. A meta module works on the output of
another module which you haven't specified in your declaration. Thus the
default, "request-attr" is used.
You cannot nest modules in your sitemap. See InputModuleAction javadocs
for a possible solution.
