I have text which contains code.
It is possible to recognize because code exist into an html tag like this
<code> print(i)
</code>
I know it is possible to remove html tags in R?
However how is it possible to remove the content into a specific tag like my case?
The code I mention exists in text.
A better example:
You can find an incredible solution if you use <code> print(i) </code> and you will solve your problem.
and I want to remove the specific tag and what it is inside the tag and have only:

I am using Scrapy and having trouble when dealing with hyper links. The article will have a name but that would be a hyperlink to another page. I can't figure out how to embed the tag text with the tag text. I am trying to practice on this article.
response.css('div.article-body p::text').extract()
You want to use a css wild card selector.
response.css('div.article-body p *::text').extract()
Alternatively, if you wanted everything inside div.article-body
response.css('div.article-body *::text').extract()
I think the easier way would be to use the XPath functions string() or normalize-space() like:
response.css('.article-body > p').xpath('normalize-space(.)').extract()
I am new to RiotJS (just discovered it yesterday). I just tried to do a little experiment which did NOT work. I created two tag files (navbar.tag and dropdown.tag). Each one was as simple as could be – simply a h3 tag with the name of the file:
// navbar.tag
<h3>Navbar</h3>
// dropdowntag
<h3>Dropdown</h3>
On my index.html page I want to nest the dropdown tag within the navbar tag like this:
<navbar>
<dropdown></dropdown>
</navbar>
That does not to work. Navbar shows up, but not dropdown. Only if I separate the two tags do both work -- i.e., like this:
<navbar></navbar>
<dropdown></dropdown>
Any idea how I can nest different tags within an html page. I know you can nest them within .tag files, but that is not what I want to do. What I want is the flexibility to nest custom tags that I create on ay html page (like I can do with regular html tags).
Any ideas?
Thanks.
You cannot modify the existing structure. RiotJS use this constraint as an advantage to ensure good performance.
To insert another tag into existing tag, use <yield/>.
See JSFiddle.
My External CSS and template was created by a friend fluent in CSS. But my friend isn't understanding that I don't know HOW to 'apply' (write) the tags in the HTML page to 'call' the CSS.
I know the difference between id (#whatever) and class (.whatever) But I don't know if a CSS entry like
.header caption (with styles listed) translates then to
'p class="header caption" with opening/closing tags ???
What I'm looking for, but not finding on the web, is a listing of how the most common tags are written as css. For example, I know
p class="left"
applies the CSS to align left, instead of HTML tag align="left" But How do I write the actual tag for
.table
.td
.tr
Is there a website to show:
"This is the tag in HTML, no External CSS" "This is the way to write the same tag for External CSS"
Second question... Other than for the 'p class' or easy tags, do I start every tag with:
class="" ?
p class="" ?
div class="" ?
When do I use SPAN vs DIV ?
I have searched for how to apply External CSS, for what tags to use--yes, I understand that every person might use different naming for divs and classes-- but I really need examples that will show the basic tags so I can plug in the 'different naming' from my
'external css'
Is there one website that shows (all on one page) examples of the tags? A website tutorial that doesn't assume novices already know how to write the tags to apply css?
Thanks
This is were I got my start in html. It teaches basic html and there are other videos that go along with it.
This will likely clear up some confusion with css.
Codeacademy.com is a much more thorough course of a multitude of web languages.
Is it possible to insert script tag using content property of CSS?
The example below inserts plain text instead of a html tag
#someDiv:before {
content:"<script>$(function(){ console.log('test');});</script>";
}
Content inserted with the content property will only ever be plain text. This is to prevent recursion. It also helps by preventing people from doing crazy things like inserting script elements with CSS.
How would you get the following tag using CSS?
<p>You can only use the text inside the tag</p>
As in xpath I'd use the following:
//p[contains(text(), "inside the tag")
PS: I can't close the xpath, it tries to auto complete with code... :S
I believe CSS3 selectors can only filter attributes, not the text within tags. So you could do something like a[href~="aspx"] to match links to aspx pages, but that's as far as content-based matching can go.
For what you want to do, you'll probably have to use javascript or server-side processing.
Have a look at quirksmode and W3 for more information.
This is what I was looking for!
p:contains("inside the tag")
