I think your problem is to show link
in html
and that should not appear in the exported data.
If it is you can define a display:column
with media
type html.
<display:column media="html" titleKey="DetailView">
<a href="action_page.html?param1=123¶m2=456">View</a>
</display:column>
<display:column media="xml" titleKey="DetailView">View</display:column>
