Method Description
In Beautiful Soup, the soup and Tag object has a convenience property – string property. It returns a single string within a PageElement, Soup or Tag. If this element has a single string child, then a NavigableString corresponding to it is returned. If this element has one child tag, return value is the ”string” attribute of the child tag, and if element itself is a string, (with no children), then the string property returns None.
Syntax
Tag.string
Example 1
The following code has the HTML string with a <div> tag that encloses three <p> elements. We find the string property of first <p> tag.
from bs4 import BeautifulSoup, NavigableString markup = '''''' <div id="Languages"> <p>Java</p> <p>Python</p> <p>C++</p> </div> '''''' soup = BeautifulSoup(markup, ''html.parser'') tag = soup.p navstr = tag.string print (navstr, type(navstr)) nav_str = str(navstr) print (nav_str, type(nav_str))
Output
Java <class ''bs4.element.NavigableString''> Java <class ''str''>
The string property returns a NavigableString. It can be cast to a regular Python string with str() function
Example 2
The string property of an element with children elements inside, returns None. Check with the <div> tag.
tag = soup.div navstr = tag.string print (navstr)
Output
None
