这是被问过很多次的问题,但我并没有真正找到我正在寻找的东西.我通常不用Java编写代码,而是用C#编写代码,所以我对Java类等不熟悉.
题
我需要创建一个需要2个参数的方法.1.一个字符串参数(xml - 所以需要转换为某个xml类)2.带有xsl文件路径位置的字符串参数
问题是我正在制作一个工厂类,必须将xml从webservice转换为我的系统可以理解的xml.我需要一个很好的解决方案.ws上的每个方法都有一个xsl文件 - 请求(将我的xml转换为ws理解的东西)和响应(转换为我的系统理解的东西).

您可能会发现Java Almanac是一个有用的资源.
特别是使用XSL转换XML文件的典型程序.从页面复制的示例(因为它一直在消失)
import java.io.*;
import org.w3c.dom.*;
import org.xml.sax.*;
import javax.xml.parsers.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.*;
import javax.xml.transform.stream.*;
public class BasicXsl {
// This method applies the xslFilename to inFilename and writes
// the output to outFilename.
public static void xsl(String inFilename, String outFilename, String xslFilename) {
try {
// Create transformer factory
TransformerFactory factory = TransformerFactory.newInstance();
// Use the factory to create a template containing the xsl file
Templates template = factory.newTemplates(new StreamSource(
new FileInputStream(xslFilename)));
// Use the template to create a transformer
Transformer xformer = template.newTransformer();
// Prepare the input and output files
Source source = new StreamSource(new FileInputStream(inFilename));
Result result = new StreamResult(new FileOutputStream(outFilename));
// Apply the xsl file to the source file and write the result
// to the output file
xformer.transform(source, result);
} catch (FileNotFoundException e) {
} catch (TransformerConfigurationException e) {
// An error occurred in the XSL file
} catch (TransformerException e) {
// An error occurred while applying the XSL file
// Get location of error in input file
SourceLocator locator = e.getLocator();
int col = locator.getColumnNumber();
int line = locator.getLineNumber();
String publicId = locator.getPublicId();
String systemId = locator.getSystemId();
}
}
}
样本输入:
<?xml version="1.0" encoding="UTF-8"?>
<map>
<entry key="key1" value="value1" />
<entry key="key2" />
</map>
示例XSLT程序:
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="html" indent="yes"/>
<xsl:template match="map">
<HTML>
<HEAD>
<TITLE>Map</TITLE>
</HEAD>
<BODY>
<xsl:apply-templates/>
</BODY>
</HTML>
</xsl:template>
<xsl:template match="entry">
<xsl:value-of select="@key"/>=<xsl:value-of select="@value"/>
<br></br>
</xsl:template>
</xsl:stylesheet>
运行该示例生成的HTML是:
<HTML>
<HEAD>
<META http-equiv="Content-Type" content="text/html; charset=UTF-8">
<TITLE>Map</TITLE>
</HEAD>
<BODY>
key1=value1<br>
key2=<br>
</BODY>
</HTML>
