在<span>标签内打印HtmlAnchor文本

Question

我有以下HtmlAnchor

<a href="/property/tx/coldspring/77331/82-bradford-ln/167035284">
 <span itemprop="streetAddress">SOMENUMBER Bradford Ln</span>, 
 <span itemprop="addressLocality">Coldspring</span>, 
 <span itemprop="addressRegion">TX</span> 
 <span itemprop="postalCode">77331</span>
</a>

当我打印htmlAnchor.getTextContent()时，不是在span标签内打印文本。如何打印全文？
