Regular expression with xml tag
<p>I have this XML string:</p>

<pre><code>   &lt;TransactionId&gt;1231231&lt;/TransactionId&gt;
   &lt;TransactionDescription&gt;Card was succesfully created: DDCARD-26913899&lt;/TransactionDescription&gt;
   &lt;Error&gt;00&lt;/Error&gt;
   &lt;ExpiryDate&gt;1084412&lt;/ExpiryDate&gt;
</code></pre>

<p>I need to extract the string after the colon( which is unique) and containing the number, in this case (DDCARD-26913899).
  The string after the value i want to extract is an XML tag and can be any other tag other than TransactionDescription.</p>

<p>I want to do it by using regular expression in Java , but i don't know how.
  Appreciate any help</p>
