With Xpath, how do you select these elements but not those?
You could use the XPath //div[starts-with(@class,"cl1 ")]; note the space after cl1. For example, In [20]: import lxml.html as LH In [21]: doc = LH.parse('data.html') In [24]: doc.xpath('//div[starts-with(@class,"cl1 ")]') Out[24]: [<Element div at 0x7f0568c68100>, <Element div at 0x7f0568c68158>] In [25]: [LH.tostring(elt) for elt in doc.xpath('//div[starts-with(@class,"cl1 ")]')] Out[25]: ['<div class="cl1 a"></div>\n',...

Obtaining position info when parsing HTML in Python
python,html,parsing,lxml,html5lib
After some additional research and more carefully reviewing of the source code of html5lib, I discovered that html5lib.tokenizer.HTMLTokenizer does retain partial position information.

How can I modify the attributes of an SVG file from Python?
You do not set the attribute again, but use its value instead of the elmenet in this line: yes_votes.set(yes_votes, str(int(yes_votes) + 1)) yes_votes contains the content of the attribute and not a reference to the attribute itself. Change it to: element.set( "data-yes", str(int(yes_votes) + 1)) ...
lxml not parsing unicode properly for HTML
It's just an encoding issue. It looks like you're using requests, which is good, because it does this work for you. First, requests guesses at the encoding, which you can access with r.encoding. For that page, requests guessed at utf-8. You could do: data = r.content.decode('UTF-8') # or data =...
XML scanning for value
The proper way to access nodes in namespace is by passing prefix-namespace URL mapping as additional argument to xpath() method, for example : ns = {'tes' : 'http://www.blah.com/client/servlet'} source_type = sourceobject.xpath('//tes:actions/tes:type/text()', namespaces=ns) Or, another way which is less recommended, by literally ignoring namespaces using xpath function local-name() : source_type =...

Installing lxml on RHEL for Python 2.7
The short answer is, not easily. I'm assuming you're using RHEL5 since you mentioned python 2.4 was in the repo. The problem is that lxml is not a pure python library, it is a rather thin wrapper around two C/C++ libraries, libxml2 and libxslt. This means that any RPM installer...

How can I set up lxml and pypy on Yosemite?
PyPy does not work with lxml (at least not very well, even if it accidentally does), due to lxml being built on top of Cython which uses CPython C API bindings. Consider using lxml-cffi instead https://github.com/amauryfa/lxml/tree/cffi
python - find xpath of element containing string
You can use getpath() to get xpath from element, for example : import requests from lxml import html page = requests.get("http://www.w3schools.com/xpath/") root = html.fromstring(page.text) tree = root.getroottree() result = root.xpath('//*[. = "XML"]') for r in result: print(tree.getpath(r)) Output : /html/body/div[3]/div/ul/li[10] /html/body/div[3]/div/ul/li[10]/a /html/body/div[4]/div/div[2]/div[2]/div[1]/div/ul/li[2] /html/body/div[5]/div/div[6]/h3 /html/body/div[6]/div/div[4]/h3 /html/body/div[7]/div/div[4]/h3 ...

Parsing xpath with python
How about using .text_content()? .text_content(): Returns the text content of the element, including the text content of its children, with no markup. table = tree.xpath('//table/tr') for item in table: print ' '.join(item.text_content().split()) join()+split() here help to replace multiple spaces with a single one. It prints: February 20, 2015 9:00 PM...
TypeError: unhashable type: 'list' while posting data
The lxml tree.xpath() method returned a list object. You cannot use a list object as a dictionary key. If you meant to retrieve the first (perhaps only) result of the XPath query, then do so explicitly: post_data={'A': 'B', token[0]: '1'} If you needed to use all results of the query...
Python and lxml.html get_element_by_id output questions
python,html,html-parsing,lxml,lxml.html
I'm afraid lxml.html cannot handle parsing this particular HTML source. It parses the h3 tag with id="productDetails" as an empty element (and this is in a default "recover" mode): <h3 class="productDescription2" id="productDetails" itemprop="description"></h3> Switch to BeautifulSoup with html5lib parser (it is extremely lenient): from urllib2 import urlopen from bs4 import...
Issue with parsing html with lxml by xpath
python,parsing,xpath,lxml,lxml.html
You can make a shorter and more reliable xpath expression and you have to use namespaces: tree.xpath('//text[@class="bar-text-label"]/text()', namespaces={'n': 'http://www.w3.org/2000/svg'}) Alternative solution could be to use selenium browser automation package: from selenium import webdriver from selenium.webdriver.common.by import By from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support import expected_conditions as EC driver = webdriver.Firefox()...
Python: Scrape Data from Web after Inputing Info
python,web-scraping,html-parsing,lxml,lxml.html
The main issue was that you needed to make a GET request, not a POST. Plus, @Paul Lo is right about the date ranges. For the sake of example, I'm querying from 2010 to 2015. Also, you have to pass query parameters as strings. 00 evaluated to 0, requests converted...
Find all HTML and non-HTML encoded URLs in string
python,html,regex,beautifulsoup,lxml
I upvoted because it triggered my curiosity. There seems to be a library called twitter-text-python, that parses Twitter posts to detect both urls and hrefs. Otherwise, I would go with the combination regex + lxml
Get inner text from lxml
That's often referred to as "inner xml" rather than "inner text". This is one possible way to get inner xml of an element : import lxml.etree as etree import lxml.html html = "<p>this is <b>the</b> good stuff<p>" tree = lxml.html.fromstring(html) node = tree.xpath("//p")[0] result = node.text + ''.join(etree.tostring(e) for e...
Fix the location of attributes in etree.Element
As for your first question, this seems to be a good answer. As for your second question, the "tostring()" method follows this standard (as per the documentation)....
Convert XML to string to find length
To serialize to a unicode string (thus, getting length in characters) in Python 2: root_str = etree.tostring(root_el, encoding=unicode) root_len_chars = len(root_str) To encode that unicode string in UTF-8, and get the length in bytes (for that encoding): root_len_bytes = len(root_str.encode('utf-8')) ...
Parsing forum posts using lxml/python
python,parsing,web-scraping,lxml,lxml.html
Find the element with xpath (not text) and use text_content() method: details = tree.xpath('.//div[contains(@id, "post_message_33583236")]')[0] print(details.text_content()) Prints: With all the talk about raising the minimum wage, I think the real issue is that people are not getting a liveable wage anymore. This applies to many skilled people too in which...
lxml: I can't remove a span tag and the text inside
You can try with strip_elements() function, like: from lxml import etree as et parser = et.XMLParser(remove_blank_text=True, recover=True) documentXml=et.parse(html_FileName, parser) for class1Node in documentXml.xpath('//div[@class="class1-text"]'): chineseNode=class1Node.xpath('.//span[@class="class3"]') et.strip_elements(chineseNode[0].getparent(), 'span', with_tail=False) print(et.tostring(documentXml)) It yields: b'<div num="1" class="class1"><div class="class1-text"><span class="class2">\n some english...
Python lxml - find tag block ammend
python,xml,xml-parsing,tags,lxml
You can make an xpath expression to get all products where territory is IE: //product[territory = "IE"] But, you need to handle an empty namespace here: from lxml import etree data = """<?xml version="1.0" encoding="UTF-8"?> <package xmlns="http://apple.com/itunes/importer" version="film5.0"> <video> <products> <product> <territory>GB</territory> <cleared_for_sale>true</cleared_for_sale> <wholesale_price_tier>1</wholesale_price_tier> </product> <product>...
Python 3.4 : LXML : Parsing Tables
python,python-3.x,datatables,lxml
Rather than use a huge long XPath as generated by Chrome, you can just search for a table with the yfnc_tabledata1 class; there is just the one: >>> tree.xpath("//table[@class='yfnc_tabledata1']") [<Element table at 0x10445e788>] Get to your <td> from there: >>> tree.xpath("//table[@class='yfnc_tabledata1']//td[1]")[0].text_content() 'Period EndingDec 31, 2014Dec 31, 2013Dec 31, 2012\n \n...
how to use lxml to get the url
res.content is a string, an HTML string. You need to use lxml.html.fromstring(): import lxml.html import requests res = requests.get('http://www.ipeen.com.tw/comment/778246') doc = lxml.html.fromstring(res.content) name = doc.xpath(".//meta[@itemprop='name']/@content") print name ...
Pandas read_html equivalent for a lxml table
I am able to now answer my own question and maybe this can be of assistance to others. I tried modifying the read_html source code in pandas without much success because of some recognition issues. Nonetheless the answer is much simpler than you might think. >>>import pandas as pd >>>import...
Saving spider results to database
python,python-3.x,sqlalchemy,web-scraping,lxml
As far as I understand, this is a Scrapy-specific question. If so, you just need to activate your pipeline in settings.py: ITEM_PIPELINES = { 'myproj.pipeline.NordfrontPipeline': 100 } This would let the engine know to send the crawled items to the pipeline (see control flow): If we are not talking about...
Problems grabbing data with xpath and lxml in Python
As far as I can see, the correct URL is http://data.treasury.gov/feed.svc/DailyTreasuryYieldCurveRateData?$filter=month%28NEW_DATE%29%20eq%201%20and%20year%28NEW_DATE%29%20eq%202015 whereas in your code there is (no ? after Data) http://data.treasury.gov/feed.svc/DailyTreasuryYieldCurveRateData$filter=month%28NEW_DATE%29%20eq%201%20and%20year%28NEW_DATE%29%20eq%202015 That's why your code currently produces the following XML: <?xml version="1.0" encoding="utf-8" standalone="yes"?> <error...
