I have the following html snippet:
<h1 class="header" itemprop="name">Some text here<span class="nobr">
I would like to get the text between the html tags, I'm struggling with this for hours now, please help me! What regex would solve my problem?
You should not use regex for that, but some HTML parser. As you didn't specify language, it is hard to help, but you will find it by googling...
If you need it just for this one case, you can use regex />(.*?)</
In Javascript you can access that info via:
document.getElementsByTagName("h1").item(0).textContent
or
document.getElementsByClassName("header").item(0).textContent
Like other's have said - you shouldn't be using regular expressions for parsing HTML. But with that aside the following will grab that text for you:
(?<=\>).+(?=\<)

From the book Oreilly Mastering Regular Expressions, I found out this example:
to take only text from O’Reilly Media
he proposed to use the regex like this <a\b([ˆ>]+)>(.+?)</a>
But for me no luck to catch only text.
Please, could enyone explain to me how build regex to catch only text.
I try to understand regex, so please, be polite, don't tell me to use another methods to parse html.
Thank you.
To reveal all the text between tags, strip off the tags.
<(?:(?:(?:(script|style|object|embed|applet|noframes|noscript|noembed)(?:\s+(?>"[\S\s]*?"|'[\S\s]*?'|(?:(?!/>)[^>])?)+)?\s*>)[\S\s]*?</\1\s*(?=>))|(?:/?[\w:]+\s*/?)|(?:[\w:]+\s+(?:"[\S\s]*?"|'[\S\s]*?'|[^>]?)+\s*/?)|\?[\S\s]*?\?|(?:!(?:(?:DOCTYPE[\S\s]*?)|(?:\[CDATA\[[\S\s]*?\]\])|(?:--[\S\s]*?--)|(?:ATTLIST[\S\s]*?)|(?:ENTITY[\S\s]*?)|(?:ELEMENT[\S\s]*?))))>

So say I have some HTML that looks like the following
This text
This Text
This Text
What regex would grab 'this text'? I'm really new to the concept of regex so have tried things like "(.*)" but not really had much success. Can anyone offer advice? :D
You can use the following regular expression
<a\b[^>]*>(.*?)</a>

You could use boost::regex in order to find url's in html code.
Related question about C++ library for HTML parsing, which you could use to parse your HTML. Then look for <a> tags.
I am having a hard time building a regular expression to grab some words from a HTML text.
Let's say I have the following :
<p style="padding-left :12px">SOME_TEXT_I_WANT</p><p>SOME_OTHER_TEXT</p>
*SOME_TEXT_I_WANT* and *SOME_OTHER_TEXT* can be either a bunch of words like "SOME RANDOM TEXT" or HTML text like "<strong>SOME BOLD TEXT</strong>"
My goal is to extract those texts with one regex.
Which language do you intend to use? Does a HTML parser exist for this language? If yes, consider using a parser.
However, if this is a "one-off", you may be able to get through with something along the lines of:
#<p[^>]*>(.*?)</p>#
The above has certain limitations, most notably it does not match <p data-something="a > b">...</p> nor nested <p>s. (I am not able to tell whether the mark-up you're trying to parse actually allows nested <p>s—just informing you on possible pitfalls.)
Assuming you are using PHP:
$html = "<p>some text here</p>"
preg_replace("/<.+?>/","", $html);
Don't use regex. If you ask why, there is a very popular SO post that describes what can happen if you try to use regex for parsing HTML.
Use your language's HTML or XML parser and extract what you need using existing functionality.
