Splunk Simple XML : Invalid character entry in XML help with CDATA in href

hi UI gurus,
we have a simple requirement to display certain links in a dashboard. All is good until there is invalid (un-encoded) characters involved. then if I use [[CDATA]] then Splunk simple XML takes the values as literal

Below is dashboard we want to achieve

<dashboard>
  <label>test HREF CDATA</label>
  <row>
    <html>
            <h1>
                HREF test with un-encoded characters
            </h1>
            <li>Lookup Links
                <ul>
                    <li>My Lookup => 
                    <a href="../lookup_editor/owner=nobody&namespace=search&lookup=xyz.csv&type=csv">Link</a>
                    </li>
                </ul>
            </li>
    </html>
  </row>
</dashboard>

Since the href is "un-encoded", this complains. When we change the <a> link as below

<![CDATA[<a href="../lookup_editor/owner=nobody&namespace=search&lookup=xyz.csv&type=csv">Link</a>]]>

Then splunk XML does not render href properly.
What's the best way to use "href" links properly in Simple XML?

PS: Even <link> don't like & in the URL as below also have same problem

   <link>
        ../lookup_editor/owner=nobody&namespace=search&lookup=xyz.csv&type=csv
   </link>

how about $url|u$?

    <drilldown>
      <set token="a_link">$click.value2$</set>
       <eval token="url">trim(mvindex(split($a_link$,"("),1),")")</eval>
       <link target="_blank">
         <![CDATA[ https://httpbin.org/json ]]></link>
    </drilldown>

this works

Got the gist of the logic. Thanks again. If you want to put as answer, will mark as "answer"

but in the above, where are we passing the "token" to the link URL?

If you write statically, you only have to convert this problem when writing it, right?
