Beautiful Soup - find_previous_siblings() Method
Method Description
The find_previous_siblings() method in Beautiful Soup package returns all siblings that appear earlier to this PAgeElement in the document and match the given criteria.
Syntax
find_previous_siblings(name, attrs, string, limit, **kwargs)
Parameters
name − A filter on tag name.
attrs − A dictionary of filters on attribute values.
string − A filter for a NavigableString with specific text.
limit − Stop looking after finding this many results.
kwargs − A dictionary of filters on attribute values.
Return Value
The find_previous_siblings() method a ResultSet of PageElements.
Example 1
Let us use the following HTML snippet for this purpose −
<p> <b> Excellent </b> <i> Python </i> <u> Tutorial </u> </p>
In the code below, we try to find all the siblings of <> tag. There are two more tags at the same level in the HTML string used for scraping.
from bs4 import BeautifulSoup soup = BeautifulSoup("<p><b>Excellent</b><i>Python</i><u>Tutorial</u></p>", 'html.parser') tag1 = soup.find('u') print ("previous siblings:") for tag in tag1.find_previous_siblings(): print (tag)
Output
<i>Python</i> <b>Excellent</b>
Example 2
The web page (index.html) has a HTML form with three input elements. We locate one with id attribute as marks and then find its previous siblings.
from bs4 import BeautifulSoup fp = open("index.html") soup = BeautifulSoup(fp, 'html.parser') tag = soup.find('input', {'id':'marks'}) sibs = tag.find_previous_sibling() print (sibs)
Output
[<input id="age" name="age" type="text"/>, <input id="nm" name="name" type="text"/>]
Example 3
The HTML string has two <p> tags. We find out the siblings previous to the one with id1 as its id attribute.
html = ''' <p><b>Excellent</b><p>Python</p><p id='id1'>Tutorial</p></p> ''' from bs4 import BeautifulSoup soup = BeautifulSoup(html, 'html.parser') tag = soup.find('p', id='id1') ptags = tag.find_previous_siblings() for ptag in ptags: print ("Tag: {}, Text: {}".format(ptag.name, ptag.text))
Output
Tag: p, Text: Python Tag: b, Text: Excellent
