Example 1
The following example shows the use of new_tag() method. A new tag for <a> element. The tag object is initialized with the href and string attributes and then inserted in the document tree.
from bs4 import BeautifulSoup
soup = BeautifulSoup(''<p>Welcome to <b>online Tutorial library</b></p>'', ''html.parser'')
tag = soup.new_tag(''a'')
tag.attrs[''href''] = "www.tutorialspoint.com"
tag.string = "Tutorialspoint"
soup.b.insert_before(tag)
print (soup)
Output
<p>Welcome to <a href="www.tutorialspoint.com">Tutorialspoint</a><b>online Tutorial library</b></p>
Example 2
In the following example, we have a HTML form with two input elements. We create a new input tag and append it to the form tag.
html = ''''''
<form>
<input type = ''text'' id = ''nm'' name = ''name''>
<input type = ''text'' id = ''age'' name = ''age''>
</form>''''''
from bs4 import BeautifulSoup
soup = BeautifulSoup(html, ''html.parser'')
tag = soup.form
newtag=soup.new_tag(''input'', attrs={''type'':''text'', ''id'':''marks'', ''name'':''marks''})
tag.append(newtag)
print (soup)
Output
<form> <input id="nm" name="name" type="text"/> <input id="age" name="age" type="text"/> <input id="marks" name="marks" type="text"/></form>
Example 3
Here we have an empty <p> tag in the HTML string. A new tag is inserted in it.
from bs4 import BeautifulSoup
soup = BeautifulSoup(''<p></p>'', ''html.parser'')
tag = soup.new_tag(''b'')
tag.string = "Hello World"
soup.p.insert(0,tag)
print (soup)
Output
<p><b>Hello World</b></p>
