如何br
在以下行中的标签后提取文本:
<div id='population'>
The Snow Leopard Survival Strategy (McCarthy <em>et al.</em> 2003, Table
II) compiled national snow leopard population estimates, updating the work
of Fox (1994). Many of the estimates are acknowledged to be rough and out
of date, but the total estimated population is 4,080-6,590, as follows:<br>
<br>
Afghanistan: 100-200?<br>
Bhutan: 100-200?<br>
China: 2,000-2,500<br>
India: 200-600<br>
Kazakhstan: 180-200<br>
Kyrgyzstan: 150-500<br>
Mongolia: 500-1,000<br>
Nepal: 300-500<br>
Pakistan: 200-420<br>
Russia: 150-200<br>
Tajikistan: 180-220<br>
Uzbekistan: 20-50
</div>
我做到了:
xpathSApply(h, '//div[@id="population"]', xmlValue)
但我现在被困住了......
