HtmlParserLibrary is a versatile .NET library designed to seamlessly convert HTML content to JSON and vice versa. This library is built with robustness and scalability in mind, making it ideal for both small-scale and large-scale data processing tasks. It comes equipped with advanced error handling, preprocessing features, and flexible usage scenarios to ensure that your HTML and JSON data conversions are reliable and efficient.
- HTML to JSON Conversion: Converts HTML structures into a well-formed JSON format. It handles complex nested elements, attributes, and text content with ease, ensuring that the output JSON is both accurate and human-readable.
- JSON to HTML Conversion: Reconstructs HTML documents from JSON structures, preserving the original document's structure, elements, attributes, and even formatting. This feature is especially useful for dynamically generating HTML content from JSON data sources.
- Error Handling: Integrates sophisticated error handling mechanisms to process XML parsing errors, enabling continued processing even with malformed or incomplete HTML. Errors are logged and the system gracefully degrades to prevent application crashes.
- Preprocessing: Includes a suite of preprocessing tools to clean and prepare HTML content for conversion. This involves fixing common HTML issues such as self-closing tags, unescaped characters, and other non-XML-compliant constructs.
- Large-Scale Processing: Optimized for handling large HTML or JSON datasets. The library can process data in chunks, making it suitable for high-performance environments where memory management is crucial.
- Customizable Output: Provides options to customize the JSON output, allowing you to include or exclude specific HTML elements, attributes, or content based on your application's requirements.
HtmlParserLibrary can be easily integrated into your .NET project via NuGet or by cloning the repository and building it manually.
dotnet add package HtmlParserLibrary- Clone the repository:
git clone https://github.com/yourusername/HtmlParserLibrary.git
- Build the project using Visual Studio or the .NET CLI:
dotnet build
The following example demonstrates how to convert a simple HTML document into a JSON object:
using HtmlParserLibrary;
string htmlContent = "<html><head><title>Example</title></head><body><p>Hello, world!</p></body></html>";
HtmlParser parser = new HtmlParser();
string jsonOutput = parser.ConvertHtmlToJson(htmlContent);
Console.WriteLine(jsonOutput);Output Example:
{
"html": {
"head": {
"title": "Example"
},
"body": {
"p": "Hello, world!"
}
}
}This example shows how to convert a JSON structure back into an HTML document:
using HtmlParserLibrary;
string jsonContent = "{ "html": { "head": { "title": "Example" }, "body": { "p": "Hello, world!" } } }";
HtmlParser parser = new HtmlParser();
string htmlOutput = parser.ConvertJsonToHtml(jsonContent);
Console.WriteLine(htmlOutput);Output Example:
<html>
<head>
<title>Example</title>
</head>
<body>
<p>Hello, world!</p>
</body>
</html>For scenarios involving large datasets, the library provides mechanisms to process data in chunks:
using HtmlParserLibrary;
string largeJsonContent = "Your large JSON content here...";
HtmlParser parser = new HtmlParser();
List<string> processedChunks = parser.ProcessJsonData(largeJsonContent);
foreach (var chunk in processedChunks)
{
Console.WriteLine(chunk);
}The library is equipped to handle and log errors during the conversion process. If an XML parsing error occurs, the library will attempt to recover and include the raw HTML content within the JSON output for manual inspection:
using HtmlParserLibrary;
try
{
string htmlContent = "<html><head><title>Example</title><body><p>Hello, world!</p></body></html>";
HtmlParser parser = new HtmlParser();
string jsonOutput = parser.ConvertHtmlToJson(htmlContent);
Console.WriteLine(jsonOutput);
}
catch (HtmlParsingException ex)
{
Console.WriteLine("An error occurred while parsing HTML: " + ex.Message);
}- Web Scraping: Easily convert scraped HTML content into structured JSON for further data processing or analysis.
- Content Management Systems (CMS): Convert user-generated HTML content into JSON for storage in a database, enabling easy retrieval and modification.
- Email Processing: Parse and convert HTML email templates into JSON, allowing for dynamic content generation or template manipulation.
- API Development: Use JSON as a standard format for handling HTML content in API responses or requests, ensuring consistent and easy-to-parse data exchange.
