substring for words
<p>text:</p>

<p>Sed ut perspiciatis unde omnis iste natus error sit voluptatem ac</p>

<p>i want to substring words not in regular way like word.Substring(1, 29).</p>

<p>regular way: </p>

<p>"Sed ut perspiciatis unde om"</p>

<p>but i want:</p>

<p>"Sed ut perspiciatis unde" </p>

<p>so only full words are shown. if word is cut inside one word before will be shown. hope understand what i am looking for.</p>
