xml转html例子2
xml转为html
2010-05-0413:29
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）
packageweb;
importjava.io.BufferedReader;
importjava.io.ByteArrayOutputStream;
importjava.io.File;
importjava.io.FileInputStream;
importjava.io.IOException;
importjava.io.InputStreamReader;
importjava.io.StringReader;
importjava.util.Properties;
importjavax.servlet.ServletException;
importjavax.servlet.http.HttpServlet;
importjavax.servlet.http.HttpServletRequest;
importjavax.servlet.http.HttpServletResponse;
importjavax.xml.transform.OutputKeys;
importjavax.xml.transform.Transformer;
importjavax.xml.transform.TransformerException;
importjavax.xml.transform.TransformerFactory;
publicclassXmlToHtmlActionextendsHttpServlet{
/**

privatestaticfinallongserialVersionUID=1L;
publicvoiddoPost(HttpServletRequestrequest,HttpServletResponseresponse)
throwsServletException,IOException{
StringxmlContent=this.getFileContent("F:/szworkspace/play/WebRoot/xsl/cd_catalog.xml");
StringxslContent=this.getFileContent("F:/szworkspace/play/WebRoot/xsl/cd_catalog.xsl");
/*xslContent="<?xmlversion=\"1.0\"?>";
xslContent+="<xsl:stylesheetxmlns:xsl=\"http://www.w3.org/TR/WD-xsl\">";
xslContent+="</xsl:stylesheet>";*/
try{
Stringhtml=this.xmlToHtml(xslContent,xmlContent);
response.getWriter().print(html);
}catch(Exceptione){
e.printStackTrace();
}
}
publicvoiddoGet(HttpServletRequestrequest,HttpServletResponseresponse)
throwsServletException,IOException{
doPost(request,response);
}
/**
*@desc获得文件内容，可能会有编码问题
*@paramfileName文件路径
**/
privateStringgetFileContent(StringfileName){
StringBuilderstrContent=newStringBuilder();
BufferedReaderbis=null;
try{
Filefile=newFile(fileName);
bis=newBufferedReader(newInputStreamReader(newFileInputStream(
file),"GBK"));
Stringline=null;
while((line=bis.readLine())!=null){
strContent.append(line).append("\n");
}
}catch(Exceptione){
e.printStackTrace();
}finally{
if(bis!=null){
try{
bis.close();
}catch(IOExceptione){
//TODOAuto-generatedcatchblock
e.printStackTrace();
}
}
}
returnstrContent.toString();
}
/**
*@desc将xml字符串转换为html
*@parambosXslSouxsl内容
*@parambosXmlSouxml内容
**/
privateStringxmlToHtml(StringxslContent,StringxmlContent)throwsTransformerException{
StringReaderbosXslSou=newStringReader(xslContent);
StringReaderbosXmlSou=newStringReader(xmlContent);
TransformerFactorytFactory=TransformerFactory.newInstance();
//获取xsl的字符流
Transformertransformer=tFactory.newTransformer(newjavax.xml.transform.stream.StreamSource(bosXslSou));
Propertiesproperties=transformer.getOutputProperties();
properties.setProperty(OutputKeys.ENCODING,"GBK");
properties.setProperty(OutputKeys.METHOD,"html");
transformer.setOutputProperties(properties);
ByteArrayOutputStreambosRes=newByteArrayOutputStream();
transformer.transform(newjavax.xml.transform.stream.StreamSource(bosXmlSou),newjavax.xml.transform.stream.StreamResult(bosRes));
StringsHtmlCont=newString(bosRes.toString());
returnsHtmlCont;
}
}
xsl文件：
<?xmlversion="1.0"encoding="GBK"?>
<xsl:stylesheetxmlns:xsl="http://www.w3.org/1999/XSL/Transform"version="1.0">
<xsl:outputmethod="html"encoding="GBK"/>
<xsl:templatematch="/">
<html>
<body>
<tableborder="2"bgcolor="yellow">
<tr>
<th>Title</th>
<th>Artist</th>
</tr>
<xsl:for-eachselect="CATALOG/CD">
<tr>
<td>
<xsl:value-ofselect="TITLE"/>
</td>
<td>
<xsl:value-ofselect="ARTIST"/>
</td>
</tr>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
xml文件：
<?xmlversion="1.0"encoding="GBK"?>
<CATALOG>
<CD>
<TITLE>EmpireBurlesque</TITLE>
<ARTIST>BobDylan</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。
