xml通讯录文档：
通讯录.xml
<?xml version="1.0" encoding="UTF-8"?> <txl> <user> <name>zhangxiaobo</name> <tel>15785308297</tel> <qqmsn>123456789</qqmsn> <mobile>18979112826</mobile> <work>student</work> <address>henan province</address> <email>[email protected]</email> <othermsg>zhengzhou</othermsg> </user> <user> <name>chencheng</name> <tel>18695308456</tel> <qqmsn>1327348747</qqmsn> <mobile>15347912823</mobile> <work>student</work> <address>jiangxi province</address> <email>[email protected]</email> <othermsg>jinggangshan</othermsg> </user> </txl>
进行XSLT转换成html文档：
TransformXML.xsl
<?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:template match="/"> <html> <head><title>Telphone</title></head> <body> <table border="1"> <tr> <th>name</th> <th>tel</th> <th>qqmsn</th> <th>mobile</th> <th>work</th> <th>address</th> <th>email</th> <th>othermsg</th> </tr> <xsl:for-each select="txl/user"> <tr> <td><xsl:value-of select="@name"/></td> <td><xsl:value-of select="@tel"/></td> <td><xsl:value-of select="@qqmsn"/></td> <td><xsl:value-of select="@mobile"/></td> <td><xsl:value-of select="@work"/></td> <td><xsl:value-of select="@address"/></td> <td><xsl:value-of select="@email"/></td> <td><xsl:value-of select="@othermsg"/></td> </tr> </xsl:for-each> </table> </body></html> </xsl:template> </xsl:stylesheet>
中间还需要一个空白的tongxunlu.xml文档（Java部分已体现），用于数据库导出内容写成xml文件，之后通过xslt转换成html格式。
