I am trying to get the HTML content of child node with lxml and xpath in Python. As shown in code below, I want to find the html content of the each of product nodes. Does it have any methods like product.html?
productGrids = tree.xpath("//div[@class='name']/parent::*")
for product in productGrids:
print #html content of product
from lxml import etree
print(etree.tostring(root, pretty_print=True))
you may see more examples here: http://lxml.de/tutorial.html
I believe you want to use the tostring() method:
from lxml import etree
tree = etree.fromstring('<html><head><title>foo</title></head><body><div class="name"><p>foo</p></div><div class="name"><ul><li>bar</li></ul></div></body></html>')
for elem in tree.xpath("//div[@class='name']"):
# pretty_print ensures that it is nicely formatted.
print etree.tostring(elem, pretty_print=True)
You can use product.text_content()
Simple function to get innerHTML or innerXML
.
Try it out directly https://pyfiddle.io/fiddle/631aa049-2785-4c58-bf82-eff4e2f8bedb/
.
function
def innerXML(elem):
elemName = elem.xpath('name(/*)')
resultStr = ''
for e in elem.xpath('/'+ elemName + '/node()'):
if(isinstance(e, str) ):
resultStr = resultStr + ''
else:
resultStr = resultStr + etree.tostring(e, encoding='unicode')
return resultStr
invocation
XMLElem = etree.fromstring("<div>I am<name>Jhon <last.name> Corner</last.name></name>.I work as <job>software engineer</job><end meta='bio' />.</div>")
print(innerXML(XMLElem))
.
Logic Behind
tostring another way to do this
x=doc.xpath("//div[@class='name']/parent::*")
print(map(etree.tostring,x))
After right clicking (copy, copy xpath) on the specific field you want (in chrome's inspector), you might get something like this:
//*[@id="specialID"]/div[12]/div[2]/h4/text()[1]
If you wanted that text element for each "specialID"
//*[@id="specialID"]/div/div[2]/h4/text()[1]
You could select another field and it'll interleave the results
//*[@id="specialID"]/div/div[2]/h4/text()[1] | //*[@id="specialID"]/div/some/weird/path[95]
Example could be improved, but it illustrates the point:
//*[@id="mw-content-text"]/div/ul[1]/li[11]/text()
from lxml import html
import requests
page = requests.get('https://en.wikipedia.org/wiki/Web_scraping')
tree = html.fromstring(page.content)
data = tree.xpath('//*[@id="mw-content-text"]/div/ul[1]/li/a/text() | //*[@id="mw-content-text"]/div/ul[1]/li/text()[1]')
print(len(data))
for i in range(len(data)):
print(data[i])
