package main
|
|
|
|
import (
|
|
"fmt"
|
|
"io/ioutil"
|
|
"log"
|
|
|
|
"tm/ted"
|
|
)
|
|
|
|
func main() {
|
|
// Create comprehensive TED parser
|
|
parser := ted.NewTEDParser()
|
|
|
|
// Read any TED XML file
|
|
xmlData, err := ioutil.ReadFile("ted_document.xml")
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
|
|
// Automatic detection and parsing
|
|
parsedDoc, err := parser.ParseXML(xmlData)
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
|
|
// Get document information

fmt.Printf("Document Type: %s\n", parsedDoc.Type)
|
|
fmt.Printf("Document ID: %s\n", document.GetID())
|
|
fmt.Printf("Notice Type: %s\n", document.GetNoticeType())

}
|
|
}
|
|
```
|
|
|
|
### Advanced Usage by Document Type
|
|
|
|
```go
|
|
// Handle specific document types
|
|
switch parsedDoc.Type {
|
|
case ted.DocumentTypeContractNotice:
|
|
cn := parsedDoc.ContractNotice
|
|
fmt.Printf("Tender Deadline: %s\n", cn.GetTenderDeadline())
|
|
amount, currency := cn.GetBudget()
|
|
fmt.Printf("Estimated Value: %s %s\n", amount, currency)

|
|
|
|
case ted.DocumentTypeDesignContest:
|
|
dc := parsedDoc.DesignContest
|
|
fmt.Printf("Design Contest ID: %s\n", dc.GetID())
|
|
if dc.ContestDesignJury != nil {
|
|
fmt.Printf("Jury Decision: %s\n", dc.ContestDesignJury.JuryDecision)
|
|
}
|
|
|
|
case ted.DocumentTypeQualificationSystemNotice:
|
|
qsn := parsedDoc.QualificationSystemNotice
|
|
fmt.Printf("Qualification System ID: %s\n", qsn.GetID())
|
|
|
|
case ted.DocumentTypeConcessionNotice:
|
|
cn := parsedDoc.ConcessionNotice
|
|
fmt.Printf("Concession ID: %s\n", cn.GetID())
|
|
if cn.ConcessionRevenue != nil {
|
|
fmt.Printf("Revenue Type: %s\n", cn.ConcessionRevenue.RevenueType)
|
|
}
|
|
|
|
case ted.DocumentTypePlanningNotice:
|
|
pn := parsedDoc.PlanningNotice
|
|
fmt.Printf("Planning ID: %s\n", pn.GetID())
|
|
fmt.Printf("Budget Lines: %d\n", len(pn.BudgetAccountLine))
|
|
|
|
case ted.DocumentTypeResultNotice:
|

rn := parsedDoc.ResultNotice
|
|
fmt.Printf("Result ID: %s\n", rn.GetID())
|
|
fmt.Printf("Tender Results: %d\n", len(rn.TenderResult))
|
|
|
|
case ted.DocumentTypeChangeNotice:
|
|
cn := parsedDoc.ChangeNotice
|
|
fmt.Printf("Change ID: %s\n", cn.GetID())
|
|
fmt.Printf("Change Reasons: %d\n", len(cn.ChangeReason))
|

|
fmt.Printf("Subcontract Calls: %d\n", len(sn.SubcontractCall))
|
|
}
|
|
```
|
|
|
|
### Working with Organizations and Extensions
|
|
|
|
```go
|
|
// Extract organization information (works for all notice types)
|
|
if doc := parsedDoc.GetDocument(); doc != nil {
|
|
// Type assertion for specific methods
|
|
if notice, ok := doc.(*ted.ContractNotice); ok {
|
|
orgs := notice.GetOrganizations()
|
|
if orgs != nil {
|
|
fmt.Printf("Organizations: %d\n", len(orgs.Organization))
|
|
for _, org := range orgs.Organization {
|
|
if org.Company != nil && org.Company.PartyName != nil {
|
|
fmt.Printf("- %s\n", org.Company.PartyName.Name)
|
|
}
|
|
}
|
|
}
|
|
|
|
// Get publication information
|
|
pub := notice.GetPublicationInfo()
|
|
if pub != nil {
|
|
fmt.Printf("Publication ID: %s\n", pub.NoticePublicationID)
|
|
fmt.Printf("OJS ID: %s\n", pub.GazetteID)
|
|
fmt.Printf("Publication Date: %s\n", pub.PublicationDate)
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
## 🔍 Document Type Detection
|
|
|
|
The parser includes intelligent document type detection:
|
|
|
|
```go
|
|
// Detect document type without parsing
|
|
docType, err := parser.DetectDocumentType(xmlData)
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
|
|
fmt.Printf("Detected document type: %s\n", docType)
|
|
|
|
// Parse specific type if known
|
|
switch docType {
|
|
case ted.DocumentTypeContractNotice:
|
|
notice, err := parser.ParseXMLAsContractNotice(xmlData)
|
|
case ted.DocumentTypePriorInformationNotice:
|
|
notice, err := parser.ParseXMLAsPriorInformationNotice(xmlData)
|
|
case ted.DocumentTypeDesignContest:
|
|
notice, err := parser.ParseXMLAsDesignContest(xmlData)
|
|
// ... other specific parsers available
|
|
}
|
|
```
|
|
|
|
## ✅ Comprehensive Validation
|
|
|
|
All notice types include thorough validation:
|
|
|
|
```go
|
|
// Validate any notice type
|
|
err := notice.Validate()
|
|
if err != nil {
|
|
log.Printf("Validation failed: %v", err)
|
|
}
|
|
```
