需要帮助掌握RelaxngValidatingReader in Commons.Xml.Relaxng

Question

环境： RelaxngValidatingReader .Net 2.0 Framework

我似乎无法让验证器等于 false，无论我如何更改 xml。我在这里错过了一些概念吗？

RNC 紧凑型

start = root
root = element root { parent1* & parent2* }
parent1 = element parent1 { element field { attribute usecase_123 {text} } }
parent2 = element parent2 { element field { attribute usecase_AAA {text} } }

XML 实例

<?xml version="1.0" encoding="utf-8" ?>
<root>
<parent1>
<hello/>
</parent1>
</root>

主程序

static void Main(string[] args)
{
RncParser parser = new RncParser(new NameTable());
TextReader source = new StreamReader("test.rnc");
RelaxngPattern grammar = parser.Parse(source);
XmlReader instance = new XmlTextReader("XMLFile1.xml");
RelaxngValidatingReader reader = new RelaxngValidatingReader(instance, grammar);
Console.WriteLine("Was the xml valid? {0}", reader.Read());
}

Answer 1

您必须重复Read()直到文件结束：

static void Main(string[] args)
{
RncParser parser = new RncParser(new NameTable());
TextReader source = new StreamReader("test.rnc");
RelaxngPattern grammar = parser.Parse(source);
XmlReader instance = new XmlTextReader("XMLFile1.xml");
RelaxngValidatingReader reader = new RelaxngValidatingReader(instance, grammar);
try {
while (!reader.EOF) {
reader.Read();
}
Console.WriteLine("validation succeeded");
}
catch (Exception ex) {
Console.WriteLine("validation failed with message:");
Console.WriteLine(ex.Message);
}
}
