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。

C#代码：
1） 导出一个Format后的文件output.xml：
View Code
///
<summary>
/// 输出Format后的xml文件output.xml
/// </summary>
private static void OutputFormatXML()
{
string xmlPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, " target.xml ");
string xsltPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, " CSRCNAV.xslt ");
string outputPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, " output.xml ");
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(xmlPath);
StringBuilder sbXml = new StringBuilder();
StringWriter stringWriter = new StringWriter(sbXml);
XmlTextWriter xmlTextWriter = new XmlTextWriter(stringWriter);
// 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;
XslCompiledTransform xslCompiledTransform = new XslCompiledTransform();
xslCompiledTransform.Load(xsltPath, settings, resolver);
xslCompiledTransform.Transform(xmlDoc, xmlTextWriter);
XmlDocument xmlFormatDoc = new XmlDocument();
xmlFormatDoc.LoadXml(sbXml.ToString());
xmlFormatDoc.Save(outputPath);
}
/// 输出Format后的xml文件output.xml
/// </summary>
private static void OutputFormatXML()
{
string xmlPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, " target.xml ");
string xsltPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, " CSRCNAV.xslt ");
string outputPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, " output.xml ");
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(xmlPath);
StringBuilder sbXml = new StringBuilder();
StringWriter stringWriter = new StringWriter(sbXml);
XmlTextWriter xmlTextWriter = new XmlTextWriter(stringWriter);
// 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;
XslCompiledTransform xslCompiledTransform = new XslCompiledTransform();
xslCompiledTransform.Load(xsltPath, settings, resolver);
xslCompiledTransform.Transform(xmlDoc, xmlTextWriter);
XmlDocument xmlFormatDoc = new XmlDocument();
xmlFormatDoc.LoadXml(sbXml.ToString());
xmlFormatDoc.Save(outputPath);
}
2） 再加上一个schema文件还可以构造成想要的DataTable：
Schema文件：
CSRCNAV.xsd
<?
xml version="1.0" encoding="utf-8"
?>
< xs:schema id ="CSRCNAVSet" xmlns ="" xmlns:xs ="http://www.w3.org/2001/XMLSchema" xmlns:msdata ="urn:schemas-microsoft-com:xml-msdata" >
< xs:element name ="CSRCNAVSet" msdata:MainDataTable ="CSRCNAV" msdata:UseCurrentLocale ="true" >
