You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: tags_if.go
    path of file: ./repos/pongo2
    
    the code of the file until where you have to start completion: package pongo2

type tagIfNode struct {
	conditions []IEvaluator
	wrappers   []*NodeWrapper
}

func (node *tagIfNode) Execute(ctx *ExecutionContext, writer TemplateWriter) *Error {
	for i, condition := range node.conditions {
		resu
    
func (node *tagIfNode) Execute(ctx *ExecutionContext, writer TemplateWriter) *Error {
	for i, condition := range node.conditions {
		result, err := condition.Evaluate(ctx)
		if err != nil {
			return err
		}

		if result.IsTrue() {
			return node.wrappers[i].Execute(ctx, writer)
		}
		// Last condition?
		if len(node.conditions) == i+1 && len(node.wrappers) > i+1 {
			return node.wrappers[i+1].Execute(ctx, writer)
		}
	}
	return nil
}
