xslt调用自定义函数(C#/Js/Java)

本文主要演示xslt调用自定义的函数，此处用C#作为编写自定义函数的语言，用C#去完成xslt对xml的筛选功能。

View Code

private static DataTable OutputDataTable()
{
string xmlPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "target.xml");
string xsltPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "CSRCNAV.xslt");
string schemaPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "CSRCNAV.xsd");

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(xmlPath);

//设置可以执行脚本函数
XsltSettings settings = new XsltSettings();
settings.EnableDocumentFunction = true;
settings.EnableScript = true;

//设置xslt可以包含外部的xslt文件
XmlUrlResolver resolver = new XmlUrlResolver();
resolver.Credentials = System.Net.CredentialCache.DefaultCredentials;

MemoryStream memoryStream = new MemoryStream();
XslCompiledTransform xslCompiledTransform = new XslCompiledTransform();
xslCompiledTransform.Load(xsltPath, settings, resolver);
xslCompiledTransform.Transform(xmlDoc, null, memoryStream);

using (DataTable dt = new DataTable())
{
dt.ReadXmlSchema(schemaPath);
memoryStream.Position = 0;
dt.ReadXml(memoryStream);

return dt;
}
}
