Difference between .string and .text BeautifulSoup

.string on a Tag type object returns a NavigableString type object. On the other hand, .text gets all the child strings and return concatenated using the given separator. Return type of .text is unicode object.

From the documentation, A NavigableString is just like a Python Unicode string, except that it also supports some of the features described in Navigating the tree and Searching the tree.

From the documentation on .string, we can see that, If the html is like this,

<td>Some Table Data</td>
<td></td>

Then, .string on the second td will return None.
But .text will return and empty string which is a unicode type object.

For more convenience,

string

• Convenience property of a tag to get the single string within this tag.
• If the tag has a single string child then the return value is that string.
• If the tag has no children or more than one child then the return value is None
• If this tag has one child tag then the return value is the ‘string’ attribute of the child tag, recursively.

And text

• Get all the child strings and return concatenated using the given separator.

If the html is like this:

<td>some text</td>
<td></td>
<td><p>more text</p></td>
<td>even <p>more text</p></td>

.string on the four td will return,

some text
None
more text
None

.text will give result like this,

some text

more text
even more text
