EssenceParser is a small C# library for parsing, traversing, and transforming HTML documents into structured, strongly-typed content trees.
It provides an object-oriented API to work with HTML as a tree of ContentNode objects, enabling transformation, filtering, serialization, and semantic analysis of HTML content.
ContentNodeTreeParserOptionsThe main class for parsing is EssenceHtmlParser. It contains key methods for working with HTML:
ReadFromString() - Loads HTML content from a string for subsequent parsing.ReadFromFileAsync() - Asynchronously loads HTML content from a file for parsing.ParseAsync() - Parses the previously loaded HTML into a ContentNodeTree structure.As a result of parsing we get ContentNodeTree, which is a hierarchical tree of content nodes, typically parsed from an HTML document. It acts as the root container for a set of top-level ContentNode instances.
The ContentNodeTree class, like ContentNode, provides a number of methods for working with an object-oriented HTML tree:
MaxDepth() - Calculates the maximum depth across all root nodes in the tree.GetNodeCount() - Computes the total number of nodes in the tree, including all descendants.FindNodes() - Searches all nodes in the tree and retains only those that match the provided predicate. This operation modifies the tree in place by flattening it to only matching nodes.Replace() - Applies a transformation to each root node using the specified function.Purge() - Removes all nodes from the tree that match the specified predicate.Clone() - Creates a deep copy of the tree, including all nodes and their attributes.ToPlainText() - Extracts and concatenates plain text from all nodes in the tree. HTML tags and structure are omitted.ToHtmlString() - Serializes the tree into an HTML-formatted string. This reflects the structure and content of the nodes, including indentation.Create an instance of ContentNodeTree and specify the options in the constructor:
var parser = new EssenceHtmlParser(new ParsingOptions());
Load your HTML from a file or pass a string directly:
string html = "<html><body><p>Hello World</p></body></html>";
parser.ReadFromString(html);
// OR
await parser.ReadFromFileAsync("your-path-to-file.html");
Now you can parse your HTML in ContentNodeTree:
var tree = await parser.ParseAsync();
You can perform operations on the received ContentNodeTree:
var scriptNodes = tree.FindNodes(n => n.Tag == HtmlTag.Script);
