I'm pretty fresh and trying to paste certain xpath from a website into sheets.
Url: "https://www.btcmarkets.net/"
Xpath: (from chrome copy xpath function) : //*[#id="LastPriceAUDBTC"]
I keep getting
formula parse error
I have managed to get the table headings on with:
Xpath: "//tr"
but not the information within
Is this even possible?
I know the google finance add-ons but I am analyzing the difference in prices of different exchanges.
QUERY #2
I would also like to
=importxml("http://www.xe.com/currencyconverter/convert/?Amount=1&From=EUR&To=CAD","//*[#id="ucc-container"]/span[2]/span[2]")
Should I be using =importDATA and shaving off what I don't want?
You need to use double quotes around the entire xpath but single quotes around the class name/id name/attribute name:
"//*[#id='LastPriceAUDBTC']"
And
=importxml("http://www.xe.com/currencyconverter/convert/?Amount=1&From=EUR&To=CAD","//*[#id='ucc-container']/span[2]/span[2]")

I am trying to use Octoparse to extract the podcast details from Marie Brown's "Beyond the kitchen table" website. https://beyondthekitchentable.co.uk/podcast/
I'm using Octoparse's free version which allows for scraping locally. The problem is that while Octoparse will automatically auto-detect the Title, Title_URL, and Content webpage data and correctly set up the Pagination, Scroll Page, and Loop item workflow to extract (Title, Title_URL, and Content fields), it does not auto-detect the 'Date' and 'Podcast time duration' fields of each individual podcast as these pieces appear to be getting embedded from an iframe. However, while I am able to custom add Date and Podcast time duration using an Absolute Xpath i.e. //div[#class="cfm-episodes-list"]/div[1]/div[2]/div[1]/iframe[1]. This results in the same value copied for each record. So when I attempt to fix this by using the Relative XPath setting in Octoparse to loop each item //span[#class="cp-episode-date"] in order to gather all individually unique, it does not get any values even though this relative Xpath //span[#class="cp-episode-date"] is finding all items when I use WebDevTools to search and find all occurrences seen within Chrome. I saw what might be another helpful post on Stackexchange about this but I was not able to make sense of it.
This portion //span[#class="cp-episode-date"] is relative Xpath as it finds multiple Date items in Chrome WebDevTools but it is not complete and I am not sure how to implement the unique Iframe traversal for the Date and Podcast time duration custom added fields I added that Octoparse's Relative XPath settings are looking for. I even tried to install the SelectorsHub Chrome browser extension but it didn't pull up the nested SelectorHub to query the Xpath the way the SelectorHub Youtube video demonstrates - it only showed me the relative Xpath I already am showing below.
Please have a look at this site using Octoparse and see if it is possible. If so, how can I do it?
When Absolute Path is used - //div[#class="cfm-episodes-list"]/div[1]/div[2]/div[1]/iframe[1]
vs.
When Relative Path is used - //span[#class="cp-episode-date"]
There are plenty of iframes inside the webpage. I don't know if Octoparse could handle this. Choose another starting point.
For example, use Apple Podcast :
https://podcasts.apple.com/gb/podcast/the-website-coach/id1587503231
Dates could be recovered with the following XPath :
//div[#class="l-row"]//time[#class]/#aria-label
Other possibility, scrape the following page :
https://feeds.captivate.fm/the-website-coach/
Dates could be recovered with the following XPath :
//h4/text()
Even easier, get directly the data from this URL (.json file) :
https://itunes.apple.com/lookup?id=1587503231&media=podcast&entity=podcastEpisode&limit=100
I am trying to get some values from an online XML document, but I cannot find the right xpath to navigate to those values. I want to import these values into a Google Spreadsheet document, which requires me to get the exact xpath.
The website is this one, and I am trying to get the information for "WillPay" information from MeetingInfo Venue=S1, Races RaceNo=1, Pools PoolInfo Pool=WIN, in OddsInfo.
For now, the value of "Number=1" should be 3350 (or something close to this, it changes quite often), and I would like to load all of these values onto the google spreadsheet document.
What I've tried is locating the xpath of all of it, and tried to my best attempt to get
"/AOSBS_XML/Meetings/MeetingInfo/Races/Pools/PoolInfo/OddsSet/OddsInfo/#WillPay"
but it doesn't work.
I've been stuck on this problem for months now and I've been avoiding it, but realised I can't anymore because it's hindering my work. Please help.
Thanks!

Try using this xpath expression:
//MeetingInfo[#Venue="S1"]/Races//RaceInfo[#RaceNo="1"]//Pools//PoolInfo[#Pool="WIN"]//OddsSet//OddsInfo[#Number="1"]/#WillPay
An alternative :
//OddsInfo[#WillPay][ancestor::PoolInfo[#Pool='WIN'] and ancestor::RaceInfo[#RaceNo='1'] and ancestor::MeetingInfo[#Venue='S1']]
I'm having trouble using xpath in Rapidminer when trying to retrieve reviews form the google play store. The problem seems to be that these reviews are in double quotes and I can't get rapidminer to spit out the text...only blanks. I have a number of other xpath queries that are working fine for other commands where i use divs and span etc. I'm able to get things to work on google spreadsheet for this query through =importXML, but not in rapidminer.
This is what I have in XPATH:
//*[#class='review-text']")
So I added a /text() to the end and still nothing. I have played around with adding //div instead of //* and have used h:/span also. I'm kind of hoping there's a special syntax for retrieving quotes that i'm unaware of?
Here is the HTML i'm looking to scrape in the image below:

Please see my comment below on further failed tests. Thanks.
I am trying to scrape data from https://www.snpedia.com/index.php/Rs7136259 to create an automated database of genomic information using google sheets.
I would like to retrieve the odds ratio contained in a table on the page. I have tried to figure out the XPath, but nothing I do works. I copied as XPath from InspectElement but that's returning a #N/A error. The information I am trying to scrape is the "Odds Ratio".
My current query:
=importxml(J2,"//*div[#id="mw-content-text"]/table/tr[7]/td")
Thanks for your input. I have searched the other links but could not figure it out. Sorry for being so green.
As noted in the comments, *div is not valid XPath. Another problem is that you have double quotes inside of double quotes, which is also invalid.
It looks like this works:
=importxml(J2,"//*[#id='mw-content-text']/table/tr[7]/td")
I continue to get this error when I try to run this XPath query
//div[#iti='0']
on this link (flight search from google)
https://www.google.com/flights/#search;f=LGW;t=JFK;d=2014-05-22;r=2014-05-26
I get something like this:
=ImportXML("https://www.google.fr/flights/#search;f=jfk;t=lgw;d=2014-02-22;r=2014-02-26";"//div[#iti='0']")
I verified and the XPath is correct (I get the answer wanted using XPath helper, the answer wanted are the data relative to the first flight selected).
I guess that it is a problem of syntax, but I tried more or less all the combinations of lower/uppercase, punctuation (replacing ; , ' ") and I tried to link the URI and the XPath query stored in cells, but nothing works.
Any help will be appreciated.
As a matter of fact, maybe it is a bug on the new google sheets or they have changed how the function works. I've activated mine and when I try to use the ImportXML it simply wont work. Since I have some old sheets here (on the old mechanism) they still work normally. If I copy and paste the script from the old to the new one it simply doesn't get any data.
Here a example:
=ImportXML("http://www.nytimes.com/pages/todayspaper/index.html";"//div[#class='columnGroup first']//h3")
If I run this on the old mechanism it works fine, but if I run the same on the new mechanism, first it will exchange my ";" for a "," and then it will bring a "#N/A" with a warning of "Error: Imported XML content cannot be parsed".
Edit (05/05/2015):
I am happy to say that I tested this function again today on the new spreadsheets and they've fixed it. I was checking that every two months and now finally they have solved this issue. The example I've added above is now returning information.
I'm sorry, but you won't be able to easily parse Google result pages. The reason your function throws an error is because the content of the page you see in your browser is generated by javascript, and Google spreadsheet doesn't execute js.
Your ImportXML has the right syntax, it doesn't return anything because the node you're looking for isn't there (importXML Parse Error).
You will have to find another source if you want these result in your spreadsheet. For info some libraries already parse the usual result page (http://www.seerinteractive.com/blog/google-scraper-in-google-docs-update for example, if it still works), but I doubt finding one for your special case will be easy.
This gives the answer (importXML Parse Error), but it's not entirely obvious.
ImportXML doesn't load Javascript. When you're building ImportXML queries on Google results, make sure you're testing against a version of the page that has Javascript turned off. You can do this using the Chrome DevTools.
(But I agree that ImportXML is fickle, idiosyncratic, and generally rage-inducing).
