遇到一个正则表达式获取key-value键值对的问题???
如下例子:

<td>dc.description</td>
<td>Host shifts are a key mechanism of parasite evolution and responsible for the emergence of many economically important pathogens. Varroa destructor has been a major factor in global honeybee (Apis mellifera) declines since shifting hosts from the Asian honeybee (Apis cerana) > 50 years ago. Until recently, only two haplotypes of V. destructor (Korea and Japan) had successfully host shifted to A. mellifera. In 2008, the sister species V. jacobsoni was found for the first time parasitizing A. mellifera in Papua New Guinea (PNG). This recent host shift presents a serious threat to world apiculture but also provides the opportunity to examine host shifting in this system. We used 12 microsatellites to compare genetic variation of V. jacobsoni on A. mellifera in PNG with mites on A. cerana in both PNG and surrounding regions. We identified two distinct lineages of V. jacobsoni reproducing on A. mellifera in PNG. Our analysis indicated independent host shift events have occurred through small numbers of mites shifting from local A. cerana populations. Additional lineages were found in the neighbouring Papua and Solomon Islands that had partially host shifted to A. mellifera, that is producing immature offspring on drone brood only. These mites were likely in transition to full colonization of A. mellifera. Significant population structure between mites on the different hosts suggested host shifted V. jacobsoni populations may not still reproduce on A. cerana, although limited gene flow may exist. Our studies provide further insight into parasite host shift evolution and help characterize this new Varroa mite threat to A. mellifera worldwide.</td>

其中 ,我要获取里面的 <td></td>标签中的内容,获取规则是这样, 以下面举例
<td>dryad.dansEditIRI</td>
<td>https://easy.dans.knaw.nl/sword2/container/3e576bf7-26e1-404c-9cc8-bc8bd53c9591</td> 第一个<td>作为key,第二个<td>作为value,请问我是用正则表达式该怎样获取呢?或者有什么办法能够方便的取得这样的key-value值呢??
java
python
因为数据是标准的xml（html是xml的特例），所以可以用xml分析工具准确的获取。
而xml分析工具有很多，前面的bs4下的BeautifulSoup是一种， xml.dom.minidom 也是一种。（这是python语言适用）
此外其他语言，比如都有自己的xml分析模块，也可以利用。而不要限于正则式（其实正则式并不适于处理这么复杂的数据）
