Question

我试图点击此网址http://ecos.fws.gov/ecp0/profile/speciesProfile?sId=6994上的文字，但无法提供正确的语法。

我想要做的是点击＆＃34;查看全部＆＃34;，但不幸的是，html中有多个＆＃34;查看全部＆＃34; s。 html看起来像这样：

<li style="margin-bottom:1em;">
<p><strong>Population location:</strong>Â Wherever found west of Mobile and Tombigbee Rivers in AL, MS, and LA</p>
<p><strong>Listing status:</strong>Â 
                    <span class="listingThreat">Threatened</span>
</p>
<ul>
<ul>
<li><b>States/US Territories</b> in which this population is known to or is believed to occur:Â 
    <a href="/ecp0/profile/countiesByState?entityId=181&amp;state=Alabama" onclick="window.open('', 'popup', 'width=800,height=550,scrollbars=yes,resizable=yes')" target="popup">Alabama</a>
    , <a href="/ecp0/profile/countiesByState?entityId=181&amp;state=Louisiana" onclick="window.open('', 'popup', 'width=800,height=550,scrollbars=yes,resizable=yes')" target="popup">Louisiana</a>
    , <a href="/ecp0/profile/countiesByState?entityId=181&amp;state=Mississippi" onclick="window.open('', 'popup', 'width=800,height=550,scrollbars=yes,resizable=yes')" target="popup">Mississippi</a>
</li>
<li><b>US Counties</b> in which this population is known to or is believed to occur:Â 
    <a href="/ecp0/profile/countiesBySpecies?entityId=181" onclick="window.open('', 'popup', 'width=800,height=550,scrollbars=yes,resizable=yes')" target="popup">View All</a></li>
<li><b>USFWS Refuges</b> in which this population is known to occur:Â 
    Bogue Chitto National Wildlife Refuge, Egmont Key National Wildlife Refuge, Grand Bay National Wildlife Refuge, Hobe Sound National Wildlife Refuge, Mississippi Sandhill Crane National Wildlife Refuge<br/>
</li>
</ul>
</ul>
</li>

我基本上需要选择li样式的位置＆＃34; margin-bottom：1em;＆＃34;并包含＆＃34;威胁＆＃34;和＆＃34;查看全部＆＃34;。不幸的是，对于提供的网址，有两个＆＃34;查看全部＆＃34;，两者都在style =＆＃34; margin-bottome：1em;＆＃34;的范围内。

我无法想出一种唯一识别第一个＆＃34;查看全部＆＃34;的方法。我在考虑某种条件路径，但不确定

Answer 1

尝试使用此xpath - "//span[@class='listingThreat']/ancestor::li//a[text()='View All']"

Python
