title: how to find <a href> element in a webpage using Rselenium?
body: <p>I have the following tag in a webpage:</p>
  
  <pre><code>&lt;a target="PARENT" href="/bin-din/WebOb/mom.ko/6/wo/asaksdaksjd
  /5.1.5.5.33.23.23"&gt;View Data Set&lt;/a&gt;
  </code></pre>
  
  <p>How can I lookup this element in Rselenium? For example if my current session is saved in remDr, what should I search for:</p>
  
  <pre><code>webElem &lt;- remDr$findElement(??)
  </code></pre>
  
  <p>I need to search the element using it's display link (View Data Set) since the href link changes over time. 
  Thanks much for your help</p>
