title: Example with Grep4j 1.5 version (for jdk 1.5)
body: <p>I need to find if any of several strings of my List exist in a List of files with extension .txt and .xml.</p>
  
  <p>I have my own list of strings: <code>"hello"</code>,<code>"goodbye"</code>,<code>"etc"</code>.</p>
  
  <p>I need the list of files with <code>"hello"</code> or <code>"goodbye"</code> or <code>"etc"</code>.</p>
  
  <p>For example:</p>
  
  <pre><code>a.csv contains:
  a|b|hello|d
  
  b.xml contains:
  &lt;a&gt;
   &lt;b&gt;&lt;/b&gt;
   &lt;c&gt;goodbye&lt;/c&gt;
  &lt;/a&gt;
  </code></pre>
  
  <p>The List of files in this case are:</p>
  
  <pre><code>/path/folder1/a.csv
  /path/folder2/b.xml
  </code></pre>
  
  <p>And then, renombrate with folder name:</p>
  
  <pre><code>/path/folder1/a.csv.folder1
  /path/folder2/b.xml.folder2
  </code></pre>
