title: How to export or create MATHML from MS word 2010?
body: <p>I have mathematical expressions in word document. Is it possible to export data as MATHML format?</p>
  
  <p>For example below formula existed in a word as a mathematical expression.</p>
  
  <p><img src="https://i.stack.imgur.com/sW7uo.png" alt="enter image description here"></p>
  
  <p>Above expression should represent as below MATHML code.</p>
  
  <pre><code>&lt;math xmlns="http://www.w3.org/1998/Math/MathML" display="block"&gt; 
  &lt;mrow&gt; 
  &lt;mi&gt;x&lt;/mi&gt; 
  &lt;mo&gt;=&lt;/mo&gt; 
  &lt;mfrac&gt; 
  &lt;mrow&gt; 
  &lt;mo&gt;&amp;#x2212;&lt;/mo&gt; 
  &lt;mi&gt;b&lt;/mi&gt; 
  &lt;mo&gt;&amp;#xB1;&lt;/mo&gt; 
  &lt;msqrt&gt; 
  &lt;mrow&gt; 
  &lt;msup&gt; 
  &lt;mi&gt;b&lt;/mi&gt; 
  &lt;mn&gt;2&lt;/mn&gt; 
  &lt;/msup&gt; 
  &lt;mo&gt;&amp;#x2212;&lt;/mo&gt; 
  &lt;mn&gt;4&lt;/mn&gt; 
  &lt;mi&gt;a&lt;/mi&gt; 
  &lt;mi&gt;c&lt;/mi&gt; 
  &lt;/mrow&gt; 
  &lt;/msqrt&gt; 
  &lt;/mrow&gt; 
  &lt;mrow&gt; 
  &lt;mn&gt;2&lt;/mn&gt; 
  &lt;mi&gt;a&lt;/mi&gt; 
  &lt;/mrow&gt; 
  &lt;/mfrac&gt; 
  </code></pre>

     </p>
  
  <p>I am able to paste the above example MATHML into word and it will create a graphic. But I am unable create MATHML from existing graphic (in MS Word).</p>
  
  <p>Thank you for your help</p>
