I have just started using Google sheet's "IMPORTXML" formular to extract webpage meta data for a SEO project.
I am stuck with the following questions:
How to use this formular and XPATH to extract a list of images (on a
page), which don't have an alt tag?
Similar as the question above, how to extract a list of images (on a page), which have an alt tag?
How to extract a list of images (on a page), which do or don't have a
title tag?
Thank you for your help in advance!
Note:
See an example of my question here:
I also referenced the formular on this post http://slesinsky.org/brian/code/xpath_checker.html, which is very old and seemd no longer working.
For the images that have an alt tag, use
=IMPORTXML(A2, "//img/#alt")
For those that don't, use
=IMPORTXML(A2, "//img[not(./#alt)]")
Note that in your example, there is only one img with no alt, so the cell will appear empty, but the selection is made.
The method of writing a code element in Asciidoc is by writing an element enclosed in the grave accent(`):
`var`
And, the method to show a link is:
link:www.awebistelink.com[var]
I am attaching an image to show these two on a website that renders Asciidoc
Image Displaying the output in an asciidoc document
When I am trying to show a link highlight of a code element inside an inline code by writing:
`link:www.awebistelink.com[var]`
It renders perfectly fine on Asciidoc Please see it here
But on the website, it doesn't show any link, and simply shows a code element like as if we declared it simply as
`var`
The correct way to make a link label appear in monospace is to apply the backticks to the label itself, not the link.
Using your example, the markup should be:
link:www.awebsitelink.com[`var`]
I found the answer,
it should be
`link:www.awebistelink.com[var]`
I still don't know how it worked but now it works just fine as intended.
I am trying to insert an image in Google Colaboratory (markdown) already saved in Google Drive using this expression  but it doesn't work. For example, the Colaboratory markdown manual shows how to insert a photo inline with this example An inline image: . Ok, that is a photo from internet, but, when I replace that photo for one already saved in my Google Drive it doesn't appear.
If you have a link like this, then I've got a solution.
https://drive.google.com/file/d/-------/view?usp=sharing
In Google Drive, right-click on the picture
Choose 'Get a sharable link'
Click to 'Copy link'. You need reader permissions. Just need the id of the image.
In my case my link is:
https://drive.google.com/file/d/1xDrydbSbijvK2JBftUz-5ovagN2B_RWH/view?usp=sharing
Now we need to copy JUST the image id:
1xDrydbSbijvK2JBftUz-5ovagN2B_RWH
We will use this base link to generate your link with the image id:
https://drive.google.com/uc?export=view&id=your_id
We then copy the id in the link:
https://drive.google.com/uc?export=view&id=1xDrydbSbijvK2JBftUz-5ovagN2B_RWH
Finally, to place as an image in Google Colab:
I tried all the answers above and nothing worked because of a small change Google has created recently(at the time of writing this post). If you click on "Get Shareable link" and paste it, it would look something like this:
https://drive.google.com/open?id=12BumFEqzKxc9mog8tYuUqvpxf10ot6W3
Now just change the open?id to uc?id and it will instantly work.
According to the answers here
From the next 3 formats only the first one worked for me:
Here is an example using plain html instead of markdown.
<figure>
<center>
<img src='https://drive.google.com/uc?id=1Rb6oXW3KufLApvID5MwxsknpoON2CkQ_' />
<figcaption>Image Caption</figcaption></center>
</figure>
This way, you can also center the image, add captions etc
Unfortunately, I have tried the methods above but they didn't work for me. Then I have tried simply right-clicking on the picture that I want to display on colab, and choose 'Get a sharable link', then the link is automatically copied to my clipboard:
The link will be something like
https://docs.google.com/uc?id=-----
Then using colab's picture inserting button, and insert that link to the (https://) part
worked like a magic!
However, if you get a link like this
https://drive.google.com/file/d/-------/view?usp=sharing
after making picture public, it somehow doesn't work.
This below method works for me:
Upload the image on google drive.
Enable link sharing (Right click on image > Get shareable link)
Change access type from 'Restricted' to 'Anyone with link', keep role as 'Viewer', click 'Done'(pop up should close).
Double click on image, Spot 'More actions' icon(top right corner, 3 vertical dots).. click on it and next select 'Open in new tab' from the more action menu, a new windows opens.
Now again, spot 'More actions' icon(top right corner, 3 vertical dots).. click on it and select 'Embed item'. It will give you a HTML 'Embed snippet'.
Copy that HTML snippet and paste it in your Colab noteboook inside a markdown or code cell.
If you use a code cell, you can use magic function %%html (change iframe width and height for your needs).
%%html
<iframe src="link_placeholder" width="600" height="300"></iframe>
I tried all of the above methods, and nothing works for me. However, there is a workaround that bypasses the use of Google Drive altogether: Simply insert the image as Base64 data in normal HTML like so:
<img src='data:image/png;base64, ...lots of base64-data.. style="max-width:100%;" />
If you, for example, are using draw.io to draw a diagram that you want to include, there is a handy option for embedding data (under file->embed). If you choose "image" in this menu, you'll get a pop-up with the relevant code for you to copy. Otherwise there are image to base64-converters online that you can use.
The downside of this method is that you'll end up with a lot of data to paste. However, if you use a dedicated cell for this purpose, there won't be any need to edit that cell ever again.
(As a side note, this method works in most Markdown editors if you for some reason are unable to include an image file. Sometimes it will also work to use SVG data instead of base64, but this does not work in Google Colab.)
Here are my solutions. I liked the first one more.
First Solution :
Step1: First use a wget to fetch the picture, do not use svg file! just png
!wget https://upload.wikimedia.org/wikipedia/commons/thumb/3/38/Jupyter_logo.svg/207px-Jupyter_logo.svg.png
Run the code
Step2: Get the name of the file from last line '207px-Jupyter_logo.svg.png', after you run the wget.
from IPython.display import Image
Image("207px-Jupyter_logo.svg.png")
Run the code!
Second Solution:
use the code below and use png file
from google.colab.patches import cv2_imshow
!curl -o logo.png https://colab.research.google.com/img/colab_favicon_256px.png
import cv2
img = cv2.imread('logo.png', cv2.IMREAD_UNCHANGED)
cv2_imshow(img)
So enjoy :)
Solution for svg or other type of files
Anyway, use your link :)
3rd from Github_md_guideline
Once you get the public URL of the image, you can insert it in a Markdown cell
With
Or in a Code cell (this trick is just in Colab, as far as I know)
With
##markdown 
So you can have Markdown within a code cell.
Link to shareable image is restricted to unique code associated to that picture. Once you update the picture (happens), then you need to update the link too.
Alternative ways are described here . My solution is given there too, so I will not copy past it here.
You can simply copy the picture in the clipboard and paste it in a markdown cell
I have an NS Window with a WebView.
My program takes in a search query and executes a Google search with it, the results being displayed in the WebView, like a browser.
Instead of displaying the search results in the WebView, I'd like to automatically open the first link and display the contents of that result instead.
As a better example, how do I display the contents of the first result of Google in a WebView?
Is this even possible?
Any help greatly appreciated. Thanks!
You could use the direct Google Search API. That would be more convinient.
https://developers.google.com/custom-search/v1/cse/list?hl=de-DE
Also you could also try to make a google request like the "I'm feeling lucky" button, which will direct you automatically to the first search result.
If you have to parse the HTML, you need to have a look at the HTML structure of the google result page. Look for specific id and class css properties in the div and a tags. If you found the ones, where the actual results are you can start parsing that content. Also i guess it would be easier to put some javascript together, that will find the first result and open it. (More easier than parsing the HTML using obj-c). You can evaluate javascript in the webview using [myWebView stringByEvaluatingJavaScriptFromString: #"put your js code here"].
Sure it is possible.
The first way to accomplish that that goes through my head is to parse the HTML response from Google, then launch a WebView with the first link you extracted.
Take a look at regular expressions to make it easy.
I've added the "html"-button to TinyMCE on an EZ Publish site so that the users can write custom html into the xmlblock-field. But html-code with div-, img- and other tags get stripped when the user saves. If I use the ''-tag I assume that the html-code inside will be rendered as viewable html-code on the web page, instead of actual html-content.
How can I enable html-editing in the ezoe?
This is what I'm trying:
Click the html-button in TinyMCE.
Write html-code:
<div style="text-align:left; width:496px; margin-left:auto; margin-right:auto;">
<img id="Image-Maps_fottoey" src="some url.jpg" width="496" height="249" alt="" />
</div>
Click "Publish". When viewing the page it has no trace of the html-code from step 2.
I've tried to add the following to my override content.ini.append.php:
[literal]
AvailableClasses[]
AvailableClasses[]=html
as per http://acidre.com/blog/ez-publish-saisir-du-contenu-directement-en-html/ but that doesn't help.
Update:
It works now with the changes that I made to content.ini.append.php. This change adds "html" as a literal option and gives you a new icon in the editor, which Nicolas pointed me to (looks like a sheet of paper and is on icon row 2, first section before the Omega-icon.
When you add the html-source in the purple edit field, the editor will create links if it discovers that you've pasted inn urls. These links are blue in the editor. You must break these links with the "Break link"-icon to the far right on icon row 1. There should be no blue hyperlinks in the editor when you save. If you've managed this, the published page should display your custom html nicely :)
The usual way of enabling literal HTML in eZ Online Editor (based on TinyMCE) in eZ Publish is to uncomment the
AvailableClasses[]=html
configuration directive in an override of content.ini. A bit more of information here : http://share.ez.no/forums/setup-design/custom-tag-stop-while-running/comment64177.
Then, the literal tag should be available to editors through the literal button in TinyMCE (this button looks like a text sheet). The dropdown proposed in the pop-up menu shows 'html'.
Allowing raw html requires a few editorial guidelines and full trust in editors, but i am sure you are aware of this.
Cheers,
Nicolas
