I coded a search function and used:
$this->db->like('title', $uri,'BOTH');
Now if the title was to be: "Förfest" searching for: "ör" returns the correct array though "förfest" or "Förfest" doesn't. Anyone know why it doesn't?
the search query is first urlencoded (with Javascript) then urldecoded (with PHP).
Fixed it myself. Problem was that i mixed $this->db->like and $this->db->where in the same function which resulted in only one being used.

So, this is about a content from a website which I want to get and put it in my Google Sheets, but I'm having difficulty understanding the class of the content.
target link: https://www.cnbc.com/quotes/?symbol=XAU=
This number is what I want to get from. Picture 1: The part which i want to scrape
And this is what the code looks like in inspector. Picture 2: The code shown in inspector
The target is inside a span attribute but the span attribute looks very difficult to me, so I tried to simplify it using this line of code here =IMPORTXML("https://www.cnbc.com/quotes/?symbol=XAU=","//table[#class='quote-horizontal regular']//tr/td/span")
Picture 3: List is shown when putting the code
After some tries, I am able to get the right target, but it confuse me, Im using this code =IMPORTXML("https://www.cnbc.com/quotes/?symbol=XAU=","//table[#class='quote-horizontal regular']//tr/td/span[#class='last original'][1]")
Picture 4: The right target is shown when the xpath query is more specified
As what you can see in 2nd Picture, 'last original' is not really the full name of the class, when I put the 'last original ng-binding' instead it gave me an error saying imported content is empty
So, correct me if my code is wrong, or accidental worked out somehow because there's another correct way?
How about this answer?
Modified formula 1:
When the name of class is last original and last original ng-binding, how about the following xpath and formula?
=IMPORTXML(A1,"//span[contains(#class,'last original')][1]")
In this case, the URL of https://www.cnbc.com/quotes/?symbol=XAU= is put in the cell "A1".
In this case, //span[contains(#class,'last original')][1] is used as the xpath. The value of span that the name of class includes last original is retrieved. So last original and last original ng-binding can be used.
Modified formula2:
As other xpath, how about the following xpath and formula?
=IMPORTXML(A1,"//meta[#itemprop='price']/#content")
It seems that the value is included in the metadata. So this sample retrieves the value from the metadata.
Reference:
IMPORTXML
To complete #Tanaike's answer, two alternatives :
=IMPORTXML(B2;"//span[#class='year high']")
"Year high" seems always equal to the current stock index value.
Or, with value retrieved from the script element :
=IMPORTXML(B2;"substring-before(substring-after(//script[contains(.,'modApi')],'""last\"":\""'),'\')")
Note : since I'm based in Europe, you need to replace ; with , in the formulas.
I am using PRAW to scrape data off of reddit. I am using the .search method to search very specific people. I can easily print the title of the submission if the keyword is in the title, but if the keyword is in the text of the submission nothing pops up. Here is the code I have so far.
import praw
reddit = praw.Reddit(----------)
alls = reddit.subreddit("all")
for submission in alls.search("Yoa ming",sort = comment, limit = 5):
print(submission.title)
When I run this code i get
Yoa Ming next to Elephant!
Obama's Yoa Ming impression
i used to yoa ming... until i took an arrow to the knee
Could someone make a rage face out of our dearest Yoa Ming? I think it would compliment his first one so well!!!
If you search Yoa Ming on reddit, there are posts that dont contain "Yoa Ming" in the title but "Yoa Ming" in the text and those are the posts I want.
Thanks.
You might need to update the version of PRAW you are using. Using v6.3.1 yields the expected outcome and includes submissions that have the keyword in the body and not the title.
Also, the sort=comment parameter should be sort='comments'. Using an invalid value for sort will not throw an error but it will fall back to the default value, which may be why you are seeing different search results between your script and the website.
My current issue is to find HTML-Tags inside of property values. I thought it would be easy to search with a query like /jcr:root/content/xgermany//*[jcr:contains(., '<strong>')] order by #jcr:score
It looks like there is a problem with the chars < and > because this query finds everything which has strong in it's property. It finds <strong>Some Text</strong> but also This is a strong man.
Also the Query Builder API didn't helped me.
Is there a possibility to solve it with a XPath or SQL Query or do I have to iterate through the whole content?
I don't fully understand why it finds This is a strong man as a result for '<strong>', but it sounds like the unexpected behavior comes from the "simple search-engine syntax" for the second argument to jcr:contains(). Apparently the < > are just being ignored as "meaningless" punctuation.
You could try quoting the search term:
/jcr:root/content/xgermany//*[jcr:contains(., '"<strong>"')]
though you may have to tweak that if your whole XPath expression is enclosed in double quotes.
Of course this will not be very robust even if it works, since you're trying to find HTML elements by searching for fixed strings, instead of actually parsing the HTML.
If you have an specific jcr:primaryType and the targeted properties you can do something like this
select * from nt:unstructured where text like '%<strong>%'
I tested it , but you need to know the properties you are intererested in.
This is jcr-sql syntax
Start using predicates like a champ this way all of this will make sense to you!
HTML Encode <strong>
HTML Decimal <strong>
Query builder is your friend:
Predicates: (like a CHAMP!)
path=/content/geometrixx
type=nt:unstructured
property=text
property.operation=like
property.value=%<strong>%
Have go here:
http://localhost:4502/libs/cq/search/content/querydebug.html?charset=UTF-8&query=path%3D%2Fcontent%2Fgeometrixx%0D%0Atype%3Dnt%3Aunstructured%0D%0Aproperty%3Dtext%0D%0Aproperty.operation%3Dlike%0D%0Aproperty.value%3D%25%3Cstrong%3E%25
Predicates: (like a CHAMP!)
path=/content/geometrixx
type=nt:unstructured
property=text
property.operation=like
property.value=%<strong>%
Have a go here:
http://localhost:4502/libs/cq/search/content/querydebug.html?charset=UTF-8&query=path%3D%2Fcontent%2Fgeometrixx%0D%0Atype%3Dnt%3Aunstructured%0D%0Aproperty%3Dtext%0D%0Aproperty.operation%3Dlike%0D%0Aproperty.value%3D%25%26lt%3Bstrong%26gt%3B%25
XPath:
/jcr:root/content/geometrixx//element(*, nt:unstructured)
[
jcr:like(#text, '%<strong>%')
]
SQL2 (already covered... NASTY YUK..)
SELECT * FROM [nt:unstructured] AS s WHERE ISDESCENDANTNODE([/content/geometrixx]) and text like '%<strong>%'
Although I'm sure it's entirely possible with a string of predicates, it's possibly heading down the wrong route. Ideally it would be better to parse the HTML when it is stored or published.
The required information would be stored on simple properties on the node in question. The query will then be a lot simpler with just a property = value query, than lots of overly complex query syntax.
It will probably be faster too.
So if you read in your HTML with something like HTMLClient and then parse it with a OSGI service, that can accurately save these properties for you. Every time the HTML is changed the process would update these properties as necessary. Just some thoughts if your SQL is getting too much.
I have Адреса магазинов on page and want to store text, then click on this link and verify that the page where am I going to contains this text in headers. So I tried to find element by xpath, and selenium.getText get the right result, but selenium.click goes to another link. Where have I made a mistake? Thanks in advance!
String m_1 = selenium.getText("xpath=html/body/div[3]/div[2]/div[1]/h4[1]");
selenium.click("xpath=html/body/div[3]/div[2]/div[1]/h4[1]");
selenium.waitForPageToLoad("30000");
assertTrue(selenium.getText("css=h3").contains(m_1));
page:http://www.svyaznoy.ru/map/
Resume:
using xpath=//descendant::a[#href='/address_shops/'][2] or css=div.deff_one_column a[href='/address_shops/'] get right results
using xpath=//a[#href='/address_shops/'] - Element is not currently visible
xpath=//a[#href='/address_shops/'][2] - Element not found
There is a missing slash at the beginning of the expression. I am kind of surprised this got through at all - the first slash means "begin at root node".
Also, it is better to select the <a> element instead of the <h>. Sometimes it works, sometimes is misclicks, sometimes the click doesn't do anything at all. Try to be as concrete as you can be.
Try this one.
String m1 = selenium.getText("xpath=/html/body/div[3]/div[2]/div/h4/a");
selenium.click("xpath=/html/body/div[3]/div[2]/div/h4/a");
selenium.waitForPageToLoad("30000");
// your variable is named m1, but m_1 was used here
assertTrue(selenium.getText("css=h3").contains(m1));
By the way, there are even better XPath expressions you could use. See the documentation, it really is helpful. Just an example, this would work, too, and is much easier to write and read:
String m1 = selenium.getText("xpath=//a[#href='/address_shops/']");
selenium.click("xpath=//a[#href='/address_shops/']");
Sorry, didn't notice page link. Css for second link can be something like that css=div.deff_one_column a[href='/address_shops/']
I am coding with Groovy, however, I don't believe its a language specific set of questions.
I actually have two questions
First Question
I've run into an issue while using HtmlUnit. It is telling me that what I am trying to grab is null.
The page I'm testing it on is:
http://browse.deviantart.com/resources/applications/psbrushes/?order=9&offset=0#/dbwam4
My code:
client = new WebClient(BrowserVersion.FIREFOX_3)
client.javaScriptEnabled = false
page = client.getPage(url)
//coming up as null
title = page.getByXPath("//html/body/div[4]/div/div[3]/div/div/div/div/div/div/div/div/div/div/h1/a")
println title
This simply prints out: []
Is this because the page uses onclick()? If so, how would I get around that? Enabling javascript creates a mess in my cmd prompt.
Second Question
I am wanting to also get the image but am having trouble because when I attempt to get the XPath (via firebug) it shows up as: //*[#id="gmi-ResViewSizer_img"]
How do I handle that?
First Answer:
/html/body/div[3]/div/div[3]/div/div/div/div/div/div/div/div/div/div/h1/a
Your XPATH was off by one in the predicate filter for the 4th div of the body, it should be the 3rd div. It appears the HTML for the site can/does change from when you had origionally snagged the XPATH using Firebug. You may need to adjust your XPATH to accommodate for potential change and be less sensitive to some differences in document structure.
Maybe something like this:
/html/body//div/h1/a
Second Answer: The XPATH that you listed will work. It may look odd/short(and may not be the most efficient), but // starts at the root node and looks throughout every node in the tree, * matches on any element(to include the img) and the [] predicate filter restricts it to those that have an id attribute who's value equals "gmi-ResViewSizer_img".
There are many other options for XPATHs that could work as well. It will also depend on how often the HTML structure changes. This is one that also works for the page referenced to select that img:
/html/body/div/div/div/div/img[1]
I had the same problem, I solved when I realize iframe tags on page, try call
((HtmlPage)current_page.getFrames()[n].getEnclosedPage()).getElementByXPath(...
where n is the position in frame in iframe collection. It's work for me !!!
Thanks a lot.
