Hpple XPath查询的问题，我有以下的HTML片段为正方体HOCR输出
<span class='ocr_line' id='line_11' title="bbox 0 482 377 539">
<span class='ocrx_word' id='word_34' title="bbox 0 484 51 539"><em>WORD1</em></span>
<span class='ocrx_word' id='word_35' title="bbox 56 482 119 528">WORD2</span>
<span class='ocrx_word' id='word_35' title="bbox 56 482 119 528"><em></em></span>
<span class='ocrx_word' id='word_36' title="bbox 137 483 171 528"><strong><em>WORD3</em></strong></span>
<span class='ocrx_word' id='word_37' title="bbox 176 482 244 528"><h1>WORD4</h1></span>
</span>
我想XPath查询字符串抢出来的BBOX字符串和字1-4节点内容。我遇到了麻烦，因为单词与<em> s和<strong> s嵌套，可能也是空的！谢谢。
