title: Extract only XML files from a zip using DotNetZip
body: <p>I want to extract all XML files in the archive, I am using DotNetZip in extracting files.</p>
  
  <p>In the Documentation of DotNetZip this is the example:</p>
  
  <pre><code>using (ZipFile zip = ZipFile.Read(zipArchiveName))
  {
    zip.ExtractSelectedEntries("name = *.xml  and  mtime &gt; 2009-01-15");
  }
  </code></pre>
  
  <p>this is my method:</p>
  
  <pre><code>private void processButton_Click(object sender, EventArgs e)
  {
      string uniquePath = string.Format(@"C:\{0}", Guid.NewGuid());
      System.IO.Directory.CreateDirectory(uniquePath);
      using (ZipFile zip = ZipFile.Read(textBox1.Text))
      {
          zip.ExtractSelectedEntries("name = *.xml");
      }
  }
  </code></pre>
  
  <p>but it extracts nothing. How can I extract all xml files using DotNetZip, thanks for your help.</p>
