Why not simply:

1. flow
cocoon.sendPage("mypipeline", {"myxml": mystring})

2. jxtemplate

<data>
${myxml}
</data>

3. sitemap
<map:generate type="jx" src="insertxml.jx"/>


Or more general:

cocoon.request.setAttribute("myxml", mystring);
cocoon.sendPage("mypipeline");

template:
${cocoon.request.getAttribute(cocoon.parameters.myxml)}

sitemap:
<map:generate type="jx" src="insertxml.jx">
	<map:parameter name="myxml" value="myxml"/>
</map:generate>
