xml转为html
2010-05-04 13:29
依据一定的格式把xml转为html，要用到xsl。xsl语法可以在网上找详细资料。现贴出代码：
java类（我是通过一个http去访问的）
package web;
import java.io.BufferedReader;
import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.StringReader;
import java.util.Properties;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.xml.transform.OutputKeys;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
public class XmlToHtmlAction extends HttpServlet {
/**
*
*/
private static final long serialVersionUID = 1L;
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String xmlContent = this.getFileContent("F:/szworkspace/play/WebRoot/xsl/cd_catalog.xml");
String xslContent = this.getFileContent("F:/szworkspace/play/WebRoot/xsl/cd_catalog.xsl");
/*xslContent = "<?xml version=\"1.0\" ?>";
xslContent +="<xsl:stylesheet xmlns:xsl=\"http://www.w3.org/TR/WD-xsl\">";
xslContent +="</xsl:stylesheet>";*/
try{
String html = this.xmlToHtml(xslContent, xmlContent);
response.getWriter().print(html);
}catch(Exception e){
e.printStackTrace();
}
}
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request,response);
}
/**
* @desc 获得文件内容，可能会有编码问题
* @param fileName 文件路径
* */
private String getFileContent(String fileName) {
StringBuilder strContent = new StringBuilder();
BufferedReader bis = null;
try {
File file = new File(fileName);
bis = new BufferedReader(new InputStreamReader(new FileInputStream(
file),"GBK"));
String line = null;
while ((line = bis.readLine()) != null) {
strContent.append(line).append("\n");
}
} catch (Exception e) {
e.printStackTrace();
} finally {
if (bis != null) {
try {
bis.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
return strContent.toString();
}
/**
* @desc 将xml字符串转换为html
* @param bosXslSou xsl内容
* @param bosXmlSou xml内容
* */
private String xmlToHtml(String xslContent, String xmlContent) throws TransformerException {
StringReader bosXslSou = new StringReader(xslContent);
StringReader bosXmlSou = new StringReader(xmlContent);
TransformerFactory tFactory = TransformerFactory.newInstance();
// 获取xsl的字符流
Transformer transformer = tFactory.newTransformer(new javax.xml.transform.stream.StreamSource(bosXslSou));
Properties properties = transformer.getOutputProperties();
properties.setProperty(OutputKeys.ENCODING,"GBK");
properties.setProperty(OutputKeys.METHOD, "html");
transformer.setOutputProperties(properties);
ByteArrayOutputStream bosRes = new ByteArrayOutputStream();
transformer.transform(new javax.xml.transform.stream.StreamSource(bosXmlSou),new javax.xml.transform.stream.StreamResult(bosRes));
String sHtmlCont = new String(bosRes.toString());
return sHtmlCont;
}
}
xsl文件：
<?xml version="1.0" encoding="GBK"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="html" encoding="GBK"/>
<xsl:template match="/">
<html>
<body>
<table border="2" bgcolor="yellow">
<tr>
<th>Title</th>
<th>Artist</th>
</tr>
<xsl:for-each select="CATALOG/CD">
<tr>
<td>
<xsl:value-of select="TITLE" />
</td>
<td>
<xsl:value-of select="ARTIST" />
</td>
</tr>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
xml文件：
<?xml version="1.0" encoding="GBK"?>
<CATALOG>
<CD>
<TITLE>Empire Burlesque</TITLE>
<ARTIST>Bob Dylan</ARTIST>
<COUNTRY>USA</COUNTRY>
<COMPANY>Columbia</COMPANY>
<PRICE>10.90</PRICE>
<YEAR>1985</YEAR>
</CD>
<CD>
<TITLE>测试</TITLE>
<ARTIST>CC</ARTIST>
<COUNTRY>USA</COUNTRY>
<COMPANY>Columbia</COMPANY>
<PRICE>10.90</PRICE>
<YEAR>1985</YEAR>
</CD>
</CATALOG>
然后自己配置sevelt吧。
