[HowTo] Read html tags from normal Variable with Structure Output

[francwalter]

Hallo

I read Native JSON and HTML Reading and I use it since a while, but since yet I used it only when I do some HTTP Requests, then I use the var. %http_data to get Tags and Values out of that HTML-Soup. Great feature!

Now, I want to get content from a variable containing only parts of HTML, e.g.:

Variable %html : 

<p>

  <strong>

    <font color="red">FirstText</font>

  </strong>

</p>

<p>

  <strong>

    <font color="green">NextText</font>

  </strong>

</p>

So to get e.g. the first content of the font-tag, here "FirstText", I just do this:

%html[font](1)

or also, here for the second font-content (NextText):

%html.font(2)

This is a very useful feature, thanks for it. The library behind it is (I think) from jsoup: Java HTML Parser

jsoup does a good job, but if the html-soup is too wrong, then it would fail. E.g. if I have such:

<p>

  SomeText

</p>

TaglessText

It wont be able to parse it, then it wouldnt be recognized as html at all.

But text like  <!-- TaglessText --> will work again :)

Thanks for that great feature!

What I still dont know is how to do something like getElementById() as in JavaScript.

This doesnt work:

Variable %html : 

<p>

  <div id="myid">SomeText</dive>

</p>

 

%html(#myid)

neither this:

%html[#myid]

How can I get an element from html by its ID? The innerHtml e.g.?

This indeed does not work, but:

 

neither this:

%html[#myid]

This in fact works! Shows "SomeText"!

See the instruction here to try jsoup: Try soup

Or  documentation about jsoup elements here: Class Selector

So I was wrong, I tested it on Google (trying to find the ammount of hits of a search (id="result-stats") but Google does not allow a search just like this, need to accept the cookies-f.ck so I got a redirect (302) and no id=result-stats in my %html_data.

Didnt test thorrowly enough, sorry.
