xslt 静态化页面的生成程序

来源：互联网发布：什么是数据漫游编辑：程序博客网时间：2024/04/30 07:55

用 xslt 生成静态页面 ,遍历数据库中的数据 ,使得访问速度大大加快,对搜索引擎优化也有好处.

下面是配置文件

<?xml version="1.0" encoding="GBK" ?>

- <Config>

<cpDataFile>CPConfig/CpData.xml</cpDataFile>

<xsltFile>CPConfig/Page.xslt</xsltFile>

<xsltFileM>CPConfig/PageM.xslt</xsltFileM>

<lsServerPath>你的数据库调用方式</lsServerPath>

<rootPath>Static/html/</rootPath>

<exMatLogo>exLog.txt</exMatLogo>

- <nearInfo>

- <nearlyItems>

</nearlyItems>

- <nearlyItems>

</nearlyItems>

- <nearlyItems>

</nearlyItems>

- <nearlyItems>

</nearlyItems>

</nearInfo>

</Config>

下面是主程序 java xslt 生成文件结合上面的 config.xml

main函数运行
