Table of Contents

For each HTML element

Iterates over a list of selected elements in an HTML document.

A typical use case for this action is extracting relevant content (or elements) from an HTML document.

Menus, scripts, headers, and footers can be removed so that the result is the 'real' content. The extracted content elements can then be inserted into a vector database, and used for Retrieval-Augmented Generation (RAG) in an AI chat.

HTML For Each Element

Example Example
This Flow retrieves an HTML page, extracts relevant elements using CSS selectors, fixes links in each element, and finally converts it to Markdown text.

Properties

Name Required Description
Title No The title of the action.
HTML content Yes The source HTML document to parse. This can be a string, a byte array, or a Stream.
CSS selectors Yes CSS selectors are the query expressions to identify elements for extraction. See below for details and examples.
Return variable name No Name of the variable containing the current element.
Description No Additional notes or comments about the action or configuration.

Returns

Each element is returned as a string.

CSS Selectors

Selectors can include HTML tags, attributes, class names, or css elements. Multiple expressions are separated with commas.

For example, given the following HTML:

<html>
    <header>test</header>
    <body>
    <div>
        <div class="x">test1</div>
        <div class="x">test2</div>
    </div>

To extract the div's using class='x', we can use the CSS selector 'div.x'.

This returns 2 elements:

    <div class="x">test1</div>

    <div class="x">test2</div>

To also include the header, we can use the selector 'header, div.x'.

This returns 3 elements:

    <header>test</header>

    <div class="x">test1</div>

    <div class="x">test2</div>
