Special functions to modify content
Apart from the methods we saw before, Beautiful Soup has the following other methods for modifying the content:
The
insert_after()andinsert_before()methods:As the name implies, these methods are used to insert a tag or string after or before another tag or string. The only parameter accepted by this method is the
NavigavleStringorTagobject.For example, we can add another
divtag withclass=ecosystemto the ecological pyramid example usinginsert_after(). To use this, we need to first find thedivtag withclass=numberwithin the first producerli; this is shown as follows:soup = BeautifulSoup(html_markup,"lxml") div_number = soup.find("div",class_="number") div_ecosystem = soup.new_tag("div") div_ecosystem['class'] = "ecosystem" div_ecosystem.append("soil") div_number.insert_after(div_ecosystem) print(soup.prettify()) #output <html> <body> <div class="ecopyramid"> <ul id="producers"> <li class="producerlist...
