 ## Usage

-The `@fin.cx/xinvoice` module is designed for handling and embedding XML data specifically tailored for xinvoice formats within PDF files. It streamlines the management of financial documents, typically involving the creation, manipulation, and embedding of structured invoice data. This section will cover a comprehensive usage guide, providing in-depth explanations of using each feature in a TypeScript environment with ESM syntax.
+The `@fin.cx/xinvoice` module streamlines the management of electronic invoices, handling the creation, manipulation, and embedding of structured invoice data in PDF files. Below are examples of common use cases.

-### Setting Up Your TypeScript Environment
-
-Before diving into the module’s functionalities, configure your TypeScript setup to handle ECMAScript modules. Here’s an example of a `tsconfig.json` configuration:
-
-```json
-{
-  "compilerOptions": {
-    "module": "ESNext",
-    "target": "ESNext",
-    "moduleResolution": "node",
-    "strict": true,
-    "esModuleInterop": true,
-    "experimentalDecorators": true,
-    "outDir": "./dist",
-    "types": ["node"]
-  },
-  "include": ["src/**/*"],
-  "exclude": ["node_modules", "dist"]
-}
-```
-
-This configuration ensures that TypeScript compiles your code using the latest ES module syntax, enabling direct and type-safe imports.
-
-### Importing the `@fin.cx/xinvoice` Module
-
-With your TypeScript environment configured, import the `@fin.cx/xinvoice` module as follows:
+### Basic Usage

 ```typescript
 import { XInvoice } from '@fin.cx/xinvoice';
-```
-
-### Core Functionality: XInvoice Class
-
-#### Introduction to XInvoice
-
-The `XInvoice` class stands at the heart of our module, enabling the creation, manipulation, and management of invoices. It allows you to incorporate XML data into PDF files seamlessly, providing a bridge between human-readable PDF formats and machine-readable XML specifications required for financial documents.
-
-#### Creating an XInvoice Instance
-
-To harness the power of `XInvoice`, instantiate it with a path to the necessary file locations for your invoice processing needs:
-
-```typescript
-const xInvoice = new XInvoice();
-```
-
-Here, we just initialize an `XInvoice` object that we can later configure with necessary inputs.
-
-#### Adding PDF and XML Data
-
-Before embedding XML data into a PDF or extracting such information, provide the `XInvoice` instance with the required PDF and XML data:
-
-```typescript
 import { promises as fs } from 'fs';

-async function loadFiles() {
-  const pdfBuffer = await fs.readFile('./path/to/your/invoice.pdf');
-  const xmlString = await fs.readFile('./path/to/your/invoice.xml', 'utf-8');
+// Create a new invoice
+const invoice = new XInvoice();
+invoice.id = 'INV-2023-001';
+invoice.from = {
+  name: 'Supplier Company',
+  // Add more details...
+};
+invoice.to = {
+  name: 'Customer Company',
+  // Add more details...
+};
+// Add more invoice details...

-  await xInvoice.addPdfBuffer(pdfBuffer);
-  await xInvoice.addXmlString(xmlString);
+// Export to XML
+const xml = await invoice.exportXml('zugferd');
+
+// Load from XML
+const loadedInvoice = await XInvoice.fromXml(xml);
+
+// Load from PDF
+const pdfBuffer = await fs.readFile('invoice.pdf');
+const invoiceFromPdf = await XInvoice.fromPdf(pdfBuffer);
+
+// Export to PDF
+const pdfWithXml = await invoice.exportPdf(pdfBuffer);
+await fs.writeFile('invoice-with-xml.pdf', pdfWithXml);
+```
+
+### Working with Different Invoice Formats
+
+```typescript
+// Load a ZUGFeRD invoice
+const zugferdXml = await fs.readFile('zugferd-invoice.xml', 'utf8');
+const zugferdInvoice = await XInvoice.fromXml(zugferdXml);
+
+// Load a Factur-X invoice
+const facturxXml = await fs.readFile('facturx-invoice.xml', 'utf8');
+const facturxInvoice = await XInvoice.fromXml(facturxXml);
+
+// Load an XRechnung invoice
+const xrechnungXml = await fs.readFile('xrechnung-invoice.xml', 'utf8');
+const xrechnungInvoice = await XInvoice.fromXml(xrechnungXml);
+```
+
+### PDF Handling
+
+```typescript
+// Extract XML from PDF
+const pdfBuffer = await fs.readFile('invoice.pdf');
+const invoice = await XInvoice.fromPdf(pdfBuffer);
+
+// Embed XML into PDF
+const existingPdf = await fs.readFile('document.pdf');
+const pdfWithInvoice = await invoice.exportPdf(existingPdf);
+await fs.writeFile('invoice-with-xml.pdf', pdfWithInvoice);
+```
+
+### Validating Invoices
+
+```typescript
+// Validate an invoice
+const validationResult = await invoice.validate();
+if (validationResult.valid) {
+  console.log('Invoice is valid');
+} else {
+  console.log('Validation errors:', validationResult.errors);
 }
 ```

-The method `addPdfBuffer` takes a `Buffer` or `Uint8Array` of the PDF file, while `addXmlString` accepts the invoice's XML representation in string format.
+## Architecture

-#### Embedding XML into PDF
+XInvoice uses a modular architecture with specialized components:

-Embedding XML data into a PDF is a significant capability of this module. Once you've loaded the PDF and XML data, invoke the `getXInvoice` method:
+### Core Components
+
+- **XInvoice**: The main class that provides a high-level API for working with invoices
+- **Decoders**: Convert format-specific XML to a common invoice model
+- **Encoders**: Convert the common invoice model to format-specific XML
+- **Validators**: Validate invoices against format-specific rules
+
+### PDF Processing
+
+- **PDF Extractors**: Extract XML from PDF files using multiple strategies:
+  - Standard Extraction: Extracts XML from standard PDF/A-3 embedded files
+  - Associated Files Extraction: Extracts XML from associated files (AF entry)
+  - Text-based Extraction: Extracts XML by searching for patterns in the PDF text
+- **PDF Embedders**: Embed XML into PDF files
+
+This modular approach ensures maximum compatibility with different PDF implementations and invoice formats.
+
+## Supported Invoice Formats
+
+| Format | Version | Read | Write | Validate |
+|--------|---------|------|-------|----------|
+| ZUGFeRD | 1.0 | ✅ | ✅ | ✅ |
+| ZUGFeRD | 2.0/2.1 | ✅ | ✅ | ✅ |
+| Factur-X | 1.0 | ✅ | ✅ | ✅ |
+| XRechnung | 1.2+ | ✅ | ✅ | ✅ |
+| UBL | 2.1 | ✅ | ✅ | ✅ |
+| CII | 16931 | ✅ | ✅ | ✅ |
+| FatturaPA | 1.2 | ✅ | ✅ | ✅ |
+
+## Advanced Usage
+
+### Custom Encoders and Decoders

 ```typescript
-await xInvoice.getXInvoice();
+// Using specific encoders
+import { ZUGFeRDEncoder, FacturXEncoder } from '@fin.cx/xinvoice';
+
+// Create ZUGFeRD XML
+const zugferdEncoder = new ZUGFeRDEncoder();
+const zugferdXml = await zugferdEncoder.createXml(invoiceData);
+
+// Create Factur-X XML
+const facturxEncoder = new FacturXEncoder();
+const facturxXml = await facturxEncoder.createXml(invoiceData);
+
+// Using specific decoders
+import { ZUGFeRDDecoder, FacturXDecoder } from '@fin.cx/xinvoice';
+
+// Decode ZUGFeRD XML
+const zugferdDecoder = new ZUGFeRDDecoder(zugferdXml);
+const zugferdData = await zugferdDecoder.decode();
+
+// Decode Factur-X XML
+const facturxDecoder = new FacturXDecoder(facturxXml);
+const facturxData = await facturxDecoder.decode();
 ```

-This process attaches the XML to the PDF document, creating a structured combination that can be saved, shared, or further processed.
-
-#### Retrieving Embedded XML from PDF
-
-To access previously embedded XML data from a PDF, use the `getXmlData` method:
-
-```typescript
-const embeddedXml = await xInvoice.getXmlData();
-console.log(embeddedXml);
-```
-
-This method extracts the XML content directly from the PDF file, decoding it into a string.
-
-### Advanced Usage: XML Parsing and Data Extraction
-
-#### Parsing XML into Structured Invoice Data
-
-When dealing with complex financial documents, converting XML into possible structured data reflects prudent practice. If your focus is analyzing invoice contents, the module offers parsing into TypeScript interfaces:
-
-```typescript
-const parsedInvoiceData = await xInvoice.getParsedXmlData();
-console.log(parsedInvoiceData);
-```
-
-The retrieval produces an object conforming to the following structure defined by `IXInvoice`:
-
-```typescript
-interface IXInvoice {
-  InvoiceNumber: string;
-  DateIssued: string;
-  Seller: IParty;
-  Buyer: IParty;
-  Items: IInvoiceItem[];
-  TotalAmount: number;
-}
-
-interface IParty {
-  Name: string;
-  Address: IAddress;
-  Contact: IContact;
-}
-
-interface IAddress {
-  Street: string;
-  City: string;
-  PostalCode: string;
-  Country: string;
-}
-
-interface IContact {
-  Email: string;
-  Phone: string;
-}
-
-interface IInvoiceItem {
-  Description: string;
-  Quantity: number;
-  UnitPrice: number;
-  TotalPrice: number;
-}
-```
-
-Each invoice object encompasses seller and buyer information, invoice items and their quantities, collectively synthesizing a comprehensive view of the document's content.
-
-### Custom Extensibility: Encoding and Decoding XML
-
-#### Factur-X/ZUGFeRD XML Encoding
-
-Beyond pre-built functionalities, the module supports custom XML encoding of structured data into PDF attachments. Utilize `FacturXEncoder` for generating standards-compliant XML:
-
-```typescript
-import { FacturXEncoder } from '@fin.cx/xinvoice';
-
-const encoder = new FacturXEncoder();
-const factorXXml = encoder.createFacturXXml(invoiceLetterData);
-```
-
-This encoder transforms invoice data into compliant Factur-X/ZUGFeRD XML format, following the European e-invoicing standard EN16931. The encoder handles all the complexities of creating valid XML including proper namespaces, required fields, and structured data elements.
-
-For backward compatibility, you can also use:
-
-```typescript
-const zugferdXml = encoder.createZugferdXml(invoiceLetterData);
-```
-
-#### XML Decoding for Multiple Invoice Formats
-
-The library supports decoding multiple electronic invoice formats through the `FacturXDecoder` class:
-
-```typescript
-import { FacturXDecoder } from '@fin.cx/xinvoice';
-
-const decoder = new FacturXDecoder(xmlString);
-const letterData = await decoder.getLetterData();
-```
-
-This decoder automatically detects the XML format (ZUGFeRD/Factur-X, UBL, or FatturaPA) and extracts relevant invoice data into a structured `ILetter` object, suitable for custom processing.
-
-#### Circular Encoding and Decoding
-
-A powerful feature of this library is the ability to perform circular encoding and decoding, allowing you to create XML from structured data and then extract the same data back from the XML:
+### Circular Encoding and Decoding

 ```typescript
 // Start with invoice data
@ -202,28 +174,36 @@ const invoiceData = { /* your structured invoice data */ };

 // Create XML
 const encoder = new FacturXEncoder();
-const xml = encoder.createFacturXXml(invoiceData);
+const xml = await encoder.createXml(invoiceData);

 // Decode XML back to structured data
 const decoder = new FacturXDecoder(xml);
-const extractedData = await decoder.getLetterData();
+const extractedData = await decoder.decode();

 // Now extractedData contains the same information as your original invoiceData
 ```

-This circular capability ensures data integrity throughout the invoice processing lifecycle.
+## Development

-### Supported Invoice Standards
+### Building the Project

-The library currently supports the following electronic invoice standards:
+```bash
+# Install dependencies
+pnpm install

- **ZUGFeRD/Factur-X** - The German and French implementations of the European e-invoicing standard EN16931, based on UN/CEFACT Cross Industry Invoice (CII) XML schema
- **UBL (Universal Business Language)** - An OASIS standard for XML business documents
- **FatturaPA** - The Italian electronic invoicing standard
+# Build the project
+pnpm run build
+```

-Each format is automatically detected during decoding, and the encoders create standards-compliant documents that pass validation.
