How to Extract Text From an HTML File Within Seconds

How Text is Embedded into an HTML File

For whatever reason you need to extract text from an HTML file, it helps to learn a bit about how texts or different types of data are embedded in an HTML file before getting to work.

The main component of an HTML file is an array of elements within which all types of data are embedded, including text. These elements are arranged in a certain way to form the layout of a web page.

This is an example taken from one of the W3School HTML exercises :

You can view the above as an element.

and

as the tags (the former marks an opening and the latter an end). Text is often wrapped between tags such as

, , , etc.

Understanding the structure of an HTML file would be helpful if you only wish to extract a particular piece of data from the HTML file (or the webpage). And this is exactly how Xpath would come into play – a query language for selecting elements from an XML/HTML document.

How to Extract Texts from HTML

There are two things you can try for capturing text from HTML files.

Programming Language

For those simple HTML documents, people who have basic coding knowledge would choose to write a program to remove all HTML tags and retain only the text inside HTML files, using Regular Expression or XPath. There are several widely used programming languages such as C#, Java, Python, JS, PHP, Go, and NodeJs that are available for computer programmers.

Some of these languages have their own parser for HTML that are available for free and you will know more about these HTML parsers by clicking here https://en.wikipedia.org/wiki/Comparison_of_HTML_parsers .

Testing and debugging your codes can take up some time which should be well expected if you’ve had any experience with coding at all.

Web Data Extraction Tools

There are many powerful web extraction tools, such as Octoparse , available for you to harvest almost everything on the web page, including the text, links, images, etc. You can convert whatever you get into a structured data format.

There’s no need for any coding, so it’s good for those who have no coding experience. In most cases, you don’t need to write Regular Expression or XPath, but it’s always going to be a plus if you want to fulfill more sophisticated data requirements. Octoparse, as it is designed for non-coders, comes with a user-friendly interface that allows you to easily interact with the web pages. It’s easy to manage and export the data without an IDE.

If you are a non-coder, Octoparse’s Auto-detect mode would be extremely helpful for you to get started. The software will detect the web page automatically and have the valuable data organized in a spreadsheet for you.

HTML Extraction Example

If you are still a newbie to any programming language but want to download information from web pages eagerly, a web scraping tool can be extremely helpful. Octoparse’s auto-detect algorithm makes data scraping easy for no-coders. For most of the webpage out there, you can get it done in only three simple steps.

I am taking this page as an example: https://techcrunch.com/

Say you want to scrape the blogs from Techcrunch (or any other similar websites), simply enter the URL into Octoparse and launch the auto-detection, you will get a scraper that helps get you the structured data as below:

scrape data from techcrunch

By clicking the “save” button, you’ve got yourself a scraper at your disposal. You can run the scraper any time you need the data or put it on schedule for regular data feeds.

how scraper works

If you opt for local runs, you’ll actually get to see the process working in real-time. When the task is completed, you can download the data in Excel, CSV, or JSON. With the help of Octoparse, data extraction from an HTML file can be this easy.

HTML to TEXT Converter Online aids in the conversion of HTML to plain text, which is easy to read and parse, as well as the saving and sharing of TEXT. If you’re doing cross-browser testing, an HTML to text converter can come in handy. For example, if you’re writing tests for a part of a web application that ensures users can’t post HTML comments to your application, you can quickly create test cases for this scenario using this programme.

This programme will remove all HTML tags from the user’s input, leaving only text (text nodes and anchor text). This utility can also be used to remove HTML tags and extract strings from HTML. After removing the HTML tags from the data, you are left with only the strings that go between the HTML tags, but the tags themselves are no longer present.

How to extract text from HTML?

Depending on your specific use case and the tools you have available, there are a few different ways to extract text from HTML. Here are a few approaches you can take:

  • A regular expression can be used to search through an HTML document and extract text. If you only want to extract specific pieces of text or work with a small amount of HTML, this can be a good option
  • Most modern web browsers include developer tools that allow you to inspect and extract web page elements. If you need to extract text from a live web page but don’t want to deal with the hassle of loading the HTML into your programme, this can be useful.
  • Depending on the programming language you use, libraries such as Readability.js for JavaScript can help you extract main content from an article while minimizing noise such as ads, sidebar, and others.

The approach you take will be determined by your specific requirements, such as the size and structure of the HTML, the information to be extracted, and the resources available. If you need to extract text from large amounts of HTML, an HTML parser is likely to be more efficient and error-free than a regular expression.

What can you do with HTML to TEXT?

When you convert HTML to plain text, you remove all formatting, images, and other non-text elements from the document, leaving only the text. This can be useful in a variety of ways, including:

  • Giving users who prefer or require it a plain text version of an HTML document
  • Text extraction from an HTML document for use in text-based analysis or search

Html to text converter examples

In this example, we pull out lorem ipsum text from HTML code. We also apply the «Collapse Whitespace» option and remove extra spaces around deleted tags.

Lorem Ipsum

What is lorem ipsum?

Lorem ipsum is a classic pangram, conditional, often meaningless placeholder text inserted into the page layout.

Is a distorted section from the philosophical treatise «On the ends of good and evil» by Cicero.

In this example, we strip all tags from a poem written in HTML code. We leave all whitespace characters in their place (by disabling collapse-whitespace option) and enable
tag line breaks (by enabling br-tags option).
