python - html- inserting sibling element containing nested tags

How to insert a sibling element containing nested tags ?



I am trying to use the insert_before function but this seems to work only for single tag.
For example, having



<html>
<body>
<div class= first_class>
<h1 id=Heder1>Header1</h1>
</div>
</body>
</html>


I try to insert above each <div class= first_class>



 <button class="accordion">
<div class="preface">
<i>Text</i>
</div>
</button>


I try to use below logic, but it doesn't work as expected. The section is not being inserted.



section_code = BeautifulSoup('<button class="accordion"><div class="preface"><i>Text</i></div></button>', 'lxml')

section = section.html.body.contents[0]

titels = soup.find_all("h1")

for title in titels:
title.parent.insert_before(section)


How can this be achieved?



Desired output



<html>
<body>
<button class="accordion">
<div class="preface">
<i>Text</i>
</div>
</button>
<div class= first_class>
<h1 id=Heder1>Header1</h1>
</div>
</body>
</html>

  • i think you need to try to use section_code instead of section in the line of the loop. i mean in the line title.parent.insert_before(section)

  • @stormfield using section_code instead of section doesn't work, it inserts the snippet in the wright place but adds unwanted tags for <html> and <body>, as it handles it as a complete html code

You just need to do a bit more. If you insert as str instead of bs4.element.Tag. The string will be html encode



from bs4 import BeautifulSoup

html = """
<html>
<body>
<div class= first_class>
<h1 id=Heder1>Header1</h1>
</div>
</body>
</html>

"""

insert = """

<button class="accordion"><div class="preface"><i>Text</i></div></button>
"""
insert_content = BeautifulSoup(insert,"lxml")
soup = BeautifulSoup(html,"lxml")

title = soup.find("div")

title.insert_before(insert_content.find("button"))
print(soup.prettify())


Output



<html>
<body>
<button class="accordion">
<div class="preface">
<i>
Text
</i>
</div>
</button>
<div class="first_class">
<h1 id="Heder1">
Header1
</h1>
</div>
</body>
</html>

  • @ kcorlidy the logic works on the self contained example, however when I pass the html code to the html variable html=BeautifulSoup(open('C://Folder/Test.html'),'lxml') then I get an error: 'Couldn't find a tree builder with the features you requested: lmxl. Do you need to install a parser library?' I use python 3.5. how need I pass the html code to the html variable to make the script working?
