标题: 请教python爬虫问题
完全对python爬虫不懂，现有html网页文件，我用了BeautifulSoup，请问如何提取/kegg-bin/show_pathway?158190805124419/hsa01100.args，hsa01100，Met**lic pathways - Homo sapiens (human)，53这四个呢？谢谢
<li><a href="/kegg-bin/show_pathway?158190805124419/hsa01100.args" target="_blank">hsa01100</a> Met**lic pathways - Homo sapiens (human) (<a href="javascript:display('hsa01100')">53</a>)

1. from bs4 import BeautifulSoup
   
2. a='<li><a href="/kegg-bin/show_pathway?158190805124419/hsa01100.args" target="_blank">hsa01100</a> Met**lic pathways - Homo sapiens (human) (<a href="javascript:display(\'hsa01100\')">53</a>)'
   
3. soup=BeautifulSoup(a,'lxml')
   
4. soup.li.contents[0]['href']
   
5. soup.li.contents[0].text
   
6. soup.li.contents[1]
   
7. soup.li.contents[2].text
