In web development and content management, checking for text content in HTML documents is a common requirement. Ensuring that an HTML document contains relevant and non-empty content is critical to maintaining the quality of web pages, preventing empty pages, and improving the user experience. Manually checking HTML documents can be time-consuming and error-prone, especially when working with large or multiple files.
Using TextContent Property – C# Example
The TextContent property of HTML elements is a standard DOM property that retrieves or sets the text content of an element and its descendants. This property is precious when developers need to check for text within an element because it provides an easy way to programmatically access and modify text content.
- Load an HTML file. Use one of the HTMLDocument() constractors to load an HTML document from a file, URL, stream, or string.
- Use the
Bodyproperty of theHTMLDocumentclass to retrieve the<body>element of the loaded HTML document. - Use the
TextContent property of the
<body>element to check and determine if it contains any non-empty content. If theTextContentproperty is not null or whitespace, it indicates that the<body>element has non-empty HTML elements. Otherwise, it indicates that the<body>element is empty.
The following C# example shows how to check if HTML text content is empty:
1// Prepare a path to a source HTML file
2string inputPath = Path.Combine(DataDir, "file.html");
3
4// Load the HTML document
5using (var document = new HTMLDocument(inputPath))
6{
7 // Get the body element
8 var body = document.Body;
9
10 // Check if the body element contains any child nodes
11 if (!string.IsNullOrWhiteSpace(body.TextContent))
12 Console.WriteLine("Non-empty HTML elements found");
13 else
14 Console.WriteLine("No child nodes found in the body element.");
