📦 AppML Data Handling – Bind JSON, XML & SQL Data to HTML Easily

📂 Introduction – Manage Data Easily with AppML

AppML is engineered to bind structured data like JSON, XML, text files, and SQL databases directly to HTML elements using a simple and declarative syntax. This eliminates the need for writing complex JavaScript or backend integration logic.

By connecting your web pages to real-time data sources, AppML enables dynamic, filterable, and sortable content views—perfect for product listings, school dashboards, and admin panels.

✅ With AppML, you can display, update, and interact with external data sources in real time—without writing any backend code.

🔍 How to filter and sort data directly within HTML views

📘 Topics Covered

📦 Topic	💡 Description
🔄 AppML – Working with Data	Learn how to load, update, and display dynamic content using data files or databases.
📁 AppML – Data Files: JSON, XML, Text	Understand how to structure and integrate different types of external data sources.
🗄️ AppML – Databases Overview	Explore how AppML communicates with backend databases like MySQL.
🧩 AppML – Using SQL Databases	Connect HTML views to SQL results using AppML’s built-in data mapping.
🧾 AppML – AppML Datafiles Format	Learn the correct syntax and field structure required in AppML-readable files.
🔍 AppML – Data Filtering and Sorting	Add instant filtering and sorting features to tables and lists directly in HTML.

🔄 AppML – Working with Data

AppML allows you to fetch data from external files using the appml-data attribute in HTML. Example:

<div appml-data="products.json">
  <h3>{{name}}</h3>
  <p>{{price}}</p>
</div>

✅ This binds data fields like name and price from the JSON file and renders them automatically.

📁 AppML – Data Files: JSON, XML, Text

AppML supports:

JSON: Most common for structured data
XML: Useful for SOAP-based APIs
Text: Plain data records in delimiter-separated format

🔹 Files should follow a schema where data is stored under the records array.

🗄️ AppML – Databases Overview

AppML can also interface with backend SQL databases via AJAX calls. The backend (like PHP) fetches data and returns it in JSON format which AppML then renders dynamically.

🧩 AppML – Using SQL Databases

Example setup:

<div appml-data="get_data.php"></div>

Your get_data.php fetches data from MySQL and returns:

{
  "records": [
    { "id": 1, "name": "Laptop", "price": "$799" },
    ...
  ]
}

✅ AppML takes care of rendering and updating the UI without any JS code.

🧾 AppML – AppML Datafiles Format

A valid AppML data file (JSON format) must look like this:

{
  "records": [
    { "name": "Item A", "price": "$50" },
    { "name": "Item B", "price": "$75" }
  ]
}

🔹 XML and text files must follow compatible formats with headers and value structures.

🔍 AppML – Data Filtering and Sorting

AppML lets you sort and filter views using simple HTML attributes like:

<input appml-filter="name">
<table>
  <tr appml-repeat="records">
    <td>{{name}}</td>
  </tr>
</table>

✅ No JavaScript is needed for search or sorting behavior—AppML manages it.

📌 Summary – Recap & Next Steps

AppML simplifies working with structured data by offering real-time binding between external files or databases and your HTML views. Whether you’re rendering tables, dashboards, or search results, AppML keeps your code minimal and maintainable.

🔍 Key Takeaways:

Supports JSON, XML, text, and SQL data integration
Auto-binds structured data into HTML
Enables filtering, sorting, and dynamic updates natively

⚙️ Real-World Relevance:
Great for product listings, dashboards, and real-time reports where backend code should be minimized.

❓ FAQs

❓ What data file formats does AppML support?
✅ JSON, XML, and plain text files—each structured for tabular data rendering.

❓ Can AppML fetch data from a database directly?
✅ Not directly, but you can use server scripts (like PHP) to return SQL results as JSON.

❓ How can I add search functionality with AppML?
✅ Use appml-filter attributes on input elements. AppML handles filtering automatically.
