Допустим у меня есть фрагмент HTML текста.

The code in many of the following examples is somewhat more explicit and less dense than <font color='red'> code <b> you are <i> likely </i> to find in actual </b> Web pages </font> . The intent here is to clarify the concepts, not to express optimal coding conciseness and style.

Который выглядит вот так

Мне нужно, замэтчить строку чистого! текста " dense than code you are likely to find in actual Web " игнорируя HTML тэги при поиске чтобы потом захайлатить этот текст, сделав желтый бэкграунд.

The code in many of the following examples is somewhat more explicit and less <span style="background:yellow"> dense than <font color='red'> code <b> you are <i> likely </i> to find in actual </b> Web </span> pages </font> . The intent here is to clarify the concepts, not to express optimal coding conciseness and style.

Может у кого есть готовый пример? Буду признателен.
