title: xgettext to generate po file from html files
body: <p>This is something I am trying so hard to get. tried a bunch of options, including this one found here <a href="https://stackoverflow.com/questions/12026651/extracting-gettext-strings-from-javascript-and-html-files-templates">Extracting gettext strings from Javascript and HTML files (templates)</a>. No go. </p>
  
  <p>this is the sample html</p>
  
  <pre><code>&lt;h1 data-bind="text: _loc('translate this')"&gt;&lt;/h1&gt;
  </code></pre>
  
  <p>the command I have tried (php, glade..)</p>
  
  <pre><code>xgettext -LPHP --force-po -o E:\Samples\poEdit\translated.po --from-code=utf-8 -k_loc E:\Samples\poEdit\html\samplePO.html
  </code></pre>
  
  <p>glade seems to look only inside tags and completely skips the keyword. Anyone solve this problem?</p>
