To insert a string or an element at a specified position in a tag in Beautiful Soup, use the Tag.insert(~) method.

The insert(~) is analogous to a Python list's insert(~) method; it takes in the following two arguments:

  • the index at which to place the element

  • the string or element to insert

Example

Consider the following HTML document:

my_html = "<p><b>I</b> enjoy <b>scraping</b> the web</p>
soup = BeautifulSoup(my_html)

Here, there are 5 locations where we can insert new content:

"<p>*<b>I</b>* enjoy *<b>scraping</b>* the web*</p>"

The 5 locations are indicated by a *.

NOTE

To insert a string or element at the last *, you should use Tag.append(~) method instead.

Inserting a string

Let's insert some string at the 2nd * (i.e. 1st index):

p_tag = soup.find("p")
p_tag.insert(1, "AAA")
print(p_tag)
<p><b>I</b>AAA enjoy <b>scraping</b> the web</p>

Inserting an element

Let's insert an element at the 3rd * (i.e. 2nd index):

# Make a new tag and initialise its content
new_tag = soup.new_tag("b")
new_tag.string = "Snacks"

p_tag = soup.find("p")
p_tag.insert(2, new_tag)
print(p_tag)
<p><b>I</b> enjoy <b>Snacks</b><b>scraping</b> the web</p>
