Xpath for //a class - ruby

I am trying to find xpath for Template 1. So far I have tried following but nothing works. I am trying to get Template 1
//a[#class='treenode' and contains(text(),'Template 1')]
//div[#id='objTree~templates~750764_children' and text()='Template 1']
//a[contains(#href, 'javascript:void(0)')]/text()
//a[contains(text(), 'Template 1')]
//a[#class='treenode' and starts-with(#href, '/javascript/')]
//a[text()="Template 1"]
//a[normalize-space(.) = 'Template 1']
Here is my HTML
<a class="treenode" href="javascript:void(0)" onclick="; highlightNode(this);" oncontextmenu="return showContext(this);">Template 1</a>
Ruby code:
link(:my_template1, :xpath=> "//a[#class='treenode' and contains(text(),'Template 1')]")
what is that I am doing wrong?

Your XPath expressions seem to be OK, but the link might be generated dynamically by some JavaScript, so you get NoSuchElementException as it's not present in the initial DOM. You can try to wait until link appears in the DOM.
I'm not sure about the Ruby syntax. Try this and let me know if it doesn't work:
wait = Selenium::WebDriver::Wait.new(:timeout => 15)
element = wait.until { driver.find_element(:link_text => "Template 1") }
element.click

How to extract links with xpath expression

This is the html markup I want to extract links from:
<div id="target">
chotosite
bit2lead
</div>
This is my xpath expression and scrapy code
links = response.xpath("//div[#id='target']/a/#href")
for link in links:
print(link)
What I expect to find is
https://www.chotosite.com
https://www.bit2lead.com
But what I found on console:
<Selector xpath="//div[#id='target']/a/#href" data='https://www.chotosite.com'>
<Selector xpath="//div[#id='target']/a/#href" data='https://www.bit2lead.com'>
How do I solve this problem ?
hope its help you.
In [18]: selector = scrapy.Selector(text="""<div id="target">
...: chotosite
...: bit2lead
...: </div>""")
In [20]: [link.xpath('#href').extract_first() for link in selector.xpath('//div/a')]
Out[20]: ['https://www.chotosite.com', 'https://www.bit2lead.com']
In order to get your desired results:
links = response.xpath("//div[#id='target']/a/#href").extract()
.extract() will create an array
Use response.xpath not xpath alone
now you can loop through your links
for link in links:
print(link)

Ruby Dashing: Issues with Jobs (on a CentOS Server)

I'm having a weird event occur, where my dashing dashboard's list widget is showing erroneous data. Here's the screenshot from my live Dashing widget
Erroneous Widget
Expected Output
What follows is the code for the widget:
Code in .erb
<li data-row="1" data-col="1" data-sizex="2" data-sizey="6">
<div data-id="facebook_insights" data-view="List" data-unordered="true" data-title="Facebook Insights: Weekly Post Views" data-moreinfo="Updated every 10 seconds"</div>
</li>
Code in job .rb
require 'mysql2'
social_count = Hash.new({ value: 0 })
time = Time.new()
date_time1 = Time.new(time.year, time.month, time.day-1)
...
SCHEDULER.every '10s' do
begin
db = Mysql.new(<HOST>,<USER>,<PASS>,<DBNAME>)
mysql1 = "SELECT <VAR> FROM <TABLE> WHERE <VAR> = '#{date_time1}' ORDER BY <VAR> DESC LIMIT 1"
...
result1 = db.query(mysql1)
...
rescue
ensure
db.close
end
result1.each do |row|
strrow1 = row[0]
$value1 = strrow1.to_i
end
...
social_count[0] = {label: "1:", value: $value1}
...
send_event('facebook_insights', { items: social_count.values })
end
What is really baffling, is that this code works for a similar widget using different data in the SQL query. Can anyone help me understand why?
I checked and re-checked the data and in my other, working code, I had my $value variables defined as $valueX with X being the number. I thought to myself "Maybe the variable names are getting confused due to them having the same name", so I changed my code to
Working Code
result1.each do |row|
strrow1 = row[0]
$variable1 = strrow1.to_i
end
...
social_count[0] = {label: "1:", value: $variable1}
Et Voila! Eureka! It worked. Not sure why it still got confused with the names, but from now on, my names will be unique!

Scrapy can't find XPath content

I'm writing a web crawler with Scrapy to download the text of talk-backs on a certain webpage.
Here is the relevant part of the code behind the webpage, for a specific talkback:
<div id="site_comment_71339" class="site_comment site_comment-even large high-rank">
<div class="talkback-topic">
<a class="show-comment" data-ajax-url="/comments/71339.js?counter=97&num=57" href="/comments/71339?counter=97&num=57">57. talk back title here </a>
</div>
<div class="talkback-message"> blah blah blah talk-back message here </div>
....etc etc etc ......
While writing an XPath to get the the message:
titles = hxs.xpath("//div[#class='site_comment site_comment-even large high-rank']")
and later on:
item["title"] = titles.xpath("div[#class='talkback-message']text()").extract()
There's no bug, but it doesn't work. Any ideas why? I suppose I'm not writing the path correctly, but I can't find the error.
Thank you :)
The whole code:
from scrapy.spider import BaseSpider
from scrapy.selector import Selector
from craigslist_sample.items import CraigslistSampleItem
class MySpider(BaseSpider):
name = "craig"
allowed_domains = ["tbk.co.il"]
start_urls = ["http://www.tbk.co.il/tag/%D7%91%D7%A0%D7%99%D7%9E%D7%99%D7%9F_%D7%A0%D7%AA%D7%A0%D7%99%D7%94%D7%95/talkbacks"]
def parse(self, response):
hxs = Selector(response)
titles = hxs.xpath("//div[#class='site_comment site_comment-even large high-rank']")
items=[]
for titles in titles:
item = CraigslistSampleItem()
item["title"] = titles.xpath("div[#class='talkback-message']text()").extract()
items.append(item)
return items
Here's a snippet of the HTML page for #site_comment_74240
<div class="site_comment site_comment-even small normal-rank" id="site_comment_74240">
<div class="talkback-topic">
144. מדיניות
</div>
<div class="talkback-username">
<table><tr>
<td>קייזרמן פרדי </td>
<td>(01.11.2013)</td>
</tr></table>
</div>
The "talkback-message" div is not in the HTML page when you first fetch it, but rather is fetched asynchronously via some AJAX query when you click on a comment title, so you'll have to fetch it for each comment.
Comment blocks, titles in you code snipper, can be grabbed using an XPath like this: //div[starts-with(#id, "site_comment_"]), i.e. all divs that have an "id" attribute beginning with string ""site_comment_"
You can also use CSS selectors with Selector.css(). In your case, you can grab comment blocks using either the "id" approach (as I've done above using XPath), so:
titles = sel.css("div[id^=site_comment_]")
or using the "site_comment" class without the other "site_comment-even", "site_comment-odd", "small", "normal-rank" or "high-rank" that vary:
titles = sel.css("div.site_comment")
Then you would issue a new Request using the URL that's in ./div[#class="talkback-topic"]/a[#class="show-comment"]/#data-ajax-url inside that comment div. Or using CSS selectors, div.talkback-topic > a.show-comment::attr(data-ajax-url) (by the way, the ::attr(...) is not standard, but is a Scrapy extension to CSS selectors using pseudo elements functions)
What you get from the AJAX call is some Javascript code, and you want to grab the content inside old.after(...)
var old = $("#site_comment_72765");
old.attr('id', old.attr('id') + '_small');
old.hide();
old.after("\n<div class=\"site_comment site_comment-odd large high-rank\" id=\"site_comment_72765\">\n <div class=\"talkback-topic\">\n <a href=\"/comments/72765?counter=42&num=109\" class=\"show-comment\" data-ajax-url=\"/comments/72765.js?counter=42&num=109\">109. ביבי - האדם הנכון בראש ממשלת ישראל(לת)<\/a>\n <\/div>\n \n <div class=\"talkback-message\">\n \n <\/div>\n \n <div class=\"talkback-username\">\n <table><tr>\n <td>ישראל <\/td>\n <td>(11.03.2012)<\/td>\n <\/tr><\/table>\n <\/div>\n <div class=\"rank-controllers\">\n <table><tr>\n \n <td class=\"rabk-link\"><a href=\"#\" data-thumb=\"/comments/72765/thumb?type=up\"><img alt=\"\" src=\"/images/elements/thumbU.png?1376839523\" /><\/a><\/td>\n <td> | <\/td>\n <td class=\"rabk-link\"><a href=\"#\" data-thumb=\"/comments/72765/thumb?type=down\"><img alt=\"\" src=\"/images/elements/thumbD.png?1376839523\" /><\/a><\/td>\n \n <td> | <\/td>\n <td>11<\/td>\n \n <\/tr><\/table>\n <\/div>\n \n <div class=\"talkback-links\">\n <a href=\"/comments/new?add_to_root=true&html_id=site_comment_72765&sibling_id=72765\">תגובה חדשה<\/a>\n \n <a href=\"/comments/72765/comments/new?html_id=site_comment_72765\">הגיבו לתגובה<\/a>\n \n <a href=\"/i/offensive?comment_id=72765\" data-noajax=\"true\">דיווח תוכן פוגעני<\/a>\n <\/div>\n \n<\/div>");
var new_comment = $("#site_comment_72765");
This is HTML data that you'll need to parse again using something Selector(text=this_ajax_html_data) and a .//div[#class="talkback-message"]//text() XPath or div.talkback-message ::text CSS selector
Here's a skeleton spider to get you going with these ideas:
from scrapy.spider import BaseSpider
from scrapy.selector import Selector
from scrapy.http import Request
from craigslist_sample.items import CraigslistSampleItem
import urlparse
import re
class MySpider(BaseSpider):
name = "craig"
allowed_domains = ["tbk.co.il"]
start_urls = ["http://www.tbk.co.il/tag/%D7%91%D7%A0%D7%99%D7%9E%D7%99%D7%9F_%D7%A0%D7%AA%D7%A0%D7%99%D7%94%D7%95/talkbacks"]
def parse(self, response):
sel = Selector(response)
comments = sel.css("div.site_comment")
for comment in comments:
item = CraigslistSampleItem()
# this probably has to be fixed
#item["title"] = comment.xpath("div[#class='talkback-message']text()").extract()
# issue an additional request to fetch the Javascript
# data containing the comment text
# and pass the incomplete item via meta dict
for url in comment.css('div.talkback-topic > a.show-comment::attr(data-ajax-url)').extract():
yield Request(url=urlparse.urljoin(response.url, url),
callback=self.parse_javascript_comment,
meta={"item": item})
break
# the line we are looking for begins with "old.after"
# and we want everythin inside the parentheses
_re_comment_html = re.compile(r'^old\.after\((?P<html>.+)\);$')
def parse_javascript_comment(self, response):
item = response.meta["item"]
# loop on Javascript content lines
for line in response.body.split("\n"):
matching = self._re_comment_html.search(line.strip())
if matching:
# what's inside the parentheses is a Javascript strings
# with escaped double-quotes
# a simple way to decode that into a Python string
# is to use eval()
# then there are these "<\/tag>" we want to remove
html = eval(matching.group("html")).replace(r"<\/", "</")
# once we have the HTML snippet, decode it using Selector()
decoded = Selector(text=html, type="html")
# and save the message text in the item
item["message"] = u''.join(decoded.css('div.talkback-message ::text').extract()).strip()
# and return it
return item
You can try it out using scrapy runspider tbkspider.py.

retrieve text from <p> on landing page using ruby watir

I have to retrieve the text from the web page and put it on console.
I am not able to get the text from this html below. Can anyone please help me on this.
<div class="twelve columns">
<h1>Your product</h1>
<p>21598: DECLINE: Decline - Property Type not acceptable under this contract</p>
<div class="row">
</div>
I tried b.div(:class => 'twelve columns').exist? on irb and it says true.
I tried this - b.div(:class => 'twelve columns').text, and it returns me the text on the header not in paragraph.
I tried with - b.div(:class => 'twelve columns').p.text, it returned me error - unable to locate element, using {:tag_name=>"p"}
Simply doing this on example you wrote worked for me:
browser.div(:class => 'twelve columns').p.text
Your best bet would be to check your page css for actually having provided elements structure, as well as that they are nested properly.
I slightly fixed you HTML:
<div class="twelve columns">
<h1>Your product</h1>
<p>21598: DECLINE: Decline - Property Type not acceptable under this contract</p>
<div class="row"></div>
</div>
Let's do a tiny example:
div = b.div(:class => 'twelve columns')
Enumeration of elements as follows:
div.elements.each do |e|
p e
end
Will do something like that:
<Watir::HTMLElement ... # <h1>Your product</h1>
<Watir::HTMLElement ... # <p>21598: DECLINE: Decline - Property Type not acceptable under this contract</p>
<Watir::HTMLElement ... #<div class="row">
If you want to specify child element P from the DIV do this:
p = div.p
or
p = div.element( :tag_name => 'p' )
And when get text of P:
p.text # >> 21598: DECLINE: Decline - Property Type not acceptable under this contract
Or event do with your single string:
b.div(:class => 'twelve columns').p.text
=> "21598: DECLINE: Decline - Property Type not acceptable under this contract"

WebDriver Capture Text by XPath

I am attempting to capture a line of text for an automated WebDriver test to use it in a comparison later on. However, I cannot find an XPath that will work with WebDriver. I have used the text() function before to capture text that is not in a tag, but in this instance that is not working. Here is the HTML, note that this text will never be the same, so I cannot use contains or similar functions.
<div id="content" class="center ui-content" data-role="content" role="main">
<div data-iscroll="scroller">
<div class="ui-corner-all ui-controlgroup ui-controlgroup-vertical" data-role="controlgroup">
<a class="ui-btn ui-corner-top ui-btn-hover-c" style="text-align: left" data-role="button" onclick="onDocumentClicked(21228772, "document.php?loan=********&folderseq=0&itemnum=21228772&pageCount=3&imageTypeName=1003 Application - Final&firstInitial=&lastName=")" href="#" data-corners="true" data-shadow="true" data-iconshadow="true" data-wrapperels="span" data-theme="c">
<span class="ui-btn-inner ui-corner-top">
<span class="ui-btn-text">
<img class="checkMark checkMark21228772 notViewedCompletely" width="15" height="15" title="You have not yet viewed this document." src="../images/white_dot.gif"/>
1003 Application - Final. (Jan 11 2012 5:04PM)
</span>
</span>
</a>
In this example, the text I am attempting to capture is: 1003 Application - Final. (Jan 11 2012 5:04PM)
I have inspected the element with Firebug and I have tried the following XPaths with no success.
html/body/div[1]/div[2]/div/div/a[1]/span/span
html/body/div[1]/div[2]/div/div/a[1]/span/span/text()
The WebDriver test is being written in C#.
You can either use this
driver.FindElement(By.XPath(".//div[#id='content']/following-sibling::span[#class='ui-btn-text']")
or
var elem = driver.FindElement(By.Id("Content"));
string text = string.Empty;
if(elem!=null) {
var textElem = elem.FindElement(By.Xpath(".//following-sibling::span[#class='ui-btn-text']"));
if(textElem!=null) text = textElem.Text();
}
I was able to solve this issue by removing the span tags from the XPath.
GetText("html/body/div[3]/div[2]/div/div/a[1]", SelectorType.XPath);
python webdriver code looks something like
driver.find_element_by_xpath("//span[#class='ui-btn-text']").text
But locator may be not uniqe, because I can't see all the code
PS Try to never use locators like html/body/div[1]/div[2]/div/div/a[1]/span/span
Approach:
Find the CSS Selector from the Given DOM
Derived CSS:css=#content div.ui-controlgroup > a[onclick*='onDocumentClicked'] > span > span
Use the C# Library Method to get the Text.
