使用JDOM处理XML数据之PDF篇（二）
XML文件的代码和
http://www.csdn.net/Develop/read_article.asp?id=20733 相同
格式转换的XSLT-FO文件的代码如下：
watchlist.pdf.xsl
<?xml version="1.0"?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0"
xmlns:fo="http://www.w3.org/1999/XSL/Format"
>
<xsl:template match ="/">
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">

margin-right="2.5cm">

<fo:region-before extent="1.5cm"/>
<fo:region-after extent="1.5cm"/>
</fo:simple-page-master>
</fo:layout-master-set>
<!-- defines the content -->
<fo:page-sequence master-name="simple">

start-indent="10pt">

</fo:table-body>

</fo:flow>
</fo:page-sequence>

</xsl:template>
</xsl:stylesheet>
最后我们在一个JSP文件中来调用这个javabean:
pdfWriter.jsp
<%@ page contentType="text/html; charset=gb2312" %>
<%@ page import="org.jdom.*" %>
<%@ page import="org.jdom.output.*" %>
<%@ page import="org.jdom.input.*" %>
<%@ page import="java.io.*" %>
<%@ page import="java.util.*" %>
<%@ page import="XML.*" %>
<%
String aa=getServletContext().getRealPath("/")+"j2ee_xml\\";
String fileName="watchlist.xml";
String trace=aa+fileName;
String styleName="watchlist.pdf.xsl";
String styleTrace=aa+styleName;
String resultName="aa.pdf";
String resultTrace=aa+resultName;
XML.PDFWriter PDFWriter = new XML.PDFWriter();
try {
PDFWriter.createPDFFromXML(styleTrace,trace, resultTrace);
} catch (Exception e) {
System.out.println(e.getMessage());
}
%>
aa.pdf就是格式化后的结果。
到现在使用XML数据的三种方式都介绍过了：
直接读取：http://www.csdn.net/Develop/read_article.asp?id=20720
使用XSLT转化成HTML：http://www.csdn.net/Develop/read_article.asp?id=20733
和这篇里介绍的使用XSL-FO转化成二进制格式。
