PS：generateHtml函数得到字符串sample如下：

<html><head> <style> .div-line{position:absolute; top:160px;} .titlefont{font-size:18;} .phigh{padding-bottom:10;} .div-title {position:static; top:8px;font-size: 22px;margin-right:180px;} td{padding-left:10px;padding-top:2px;padding-bottom:2px;} br{line-height:10px;} p{padding-bottom:10;margin:2;} body{font-family:宋体;font-size:16px;} table{border-style:solid;font-size:16px;border-collapse:collapse;} td textarea{border-style:solid; border-color:#000000;} div#sequence {background-color:#ffff99;height:30px;width:150px;float:left;} div#no {background-color:#ffff99;height:30px;width:150px;float:right;} </style> </head> <body> <table border="0" bordercolor="#FFFFFF" bgcolor="#FFFFFF" bordertype="1" style="margin-bottom:4px;margin-top:12px" align=center width=100%> <tr> <td width=80% class="phigh">当日序列号:2</td> <td width=20% class="phigh">单号:</td> </tr> </table> <br /> <div class="div-title"> <b><u><p style="text-align:center; margin-left:180">CNY BOND TRADING (信用买卖)</p></u></b></div> <br/> <table border="1" cellspacing="0" bordercolor="#000000" bgcolor="#FFFFFF" style="margin-bottom:4px;" width="100%"> <tr> <td width="50%"> <div> <p>TRADE DATE</p> <p>成交日期2015-10-26</p> </div> </td> <td width="50%"> <div> <p>TIME</p> <p>时间17:11:00</p> </div> </td> </tr> </table> <br/> <table border="0" bordercolor="#FFFFFF" bgcolor="#FFFFFF" width="100%"> <tbody> <tr> <td width="50%"> <b>BUYER(买入方)</b> </td> <td width="50%"> <b>SELLER(卖出方)</b> </td> </tr> </tbody></table> <table border="1" cellspacing="0" bordercolor="#000000" bgcolor="#FFFFFF" width="100%"> <tbody><tr> <td width="50%"> <div> <p class="phigh">NAME 名称:鹏扬投资北京(焦翠)</p> <p class="phigh">CITY 分行/城市:</p><br/> </div> </td> <td width="50%"> <div> <p class="phigh">NAME 名称:</p> <p>CITY 分行/城市:</p> </div> </td> </tr> <tr> <td width="50%"> <div> <p>Brokerage 佣金:0.00</p> <p>Broker 经纪人:傅尚杰sjfu</p> <p>使用以下方式确认交易</p> <table border="0" bordercolor="#FFFFFF"width="100%" style="padding-left:0px;"> <tr> <td width="18%" style="padding-left:0px;">直线(</td> <td width="25%" style="padding-left:0px;"></td> <td width="25%" style="padding-left:0px;">) 电话(</td> <td width="25%" style="padding-left:0px;"></td> <td width="7%" style="padding-left:0px;">)</td> </tr> <tr> <td width="18%" style="padding-left:0px;">RM(</td> <td width="25%" style="padding-left:0px;"></td> <td width="25%" style="padding-left:0px;">) QQ(</td> <td width="25%" style="padding-left:0px;"></td> <td width="7%" style="padding-left:0px;">)</td> </tr> </table> </div> </td> <td width="50%"> <div> <p>Brokerage 佣金:0.00 </p> <p>Broker 经纪人:</p> <p>使用以下方式确认交易</p> <table border="0" bordercolor="#FFFFFF" width="100%" style="padding-left:0px;"> <tr> <td width="18%" style="padding-left:0px;">直线(</td> <td width="25%" style="padding-left:0px;"></td> <td width="25%" style="padding-left:0px;">) 电话(</td> <td width="25%" style="padding-left:0px;"></td> <td width="7%" style="padding-left:0px;">)</td> </tr> <tr> <td width="18%" style="padding-left:0px;">RM(</td> <td width="25%" style="padding-left:0px;"></td> <td width="25%" style="padding-left:0px;">) QQ(</td> <td width="25%" style="padding-left:0px;"></td> <td width="7%" style="padding-left:0px;">)</td> </tr> </table> </div> </td> </tr> </tbody> </table><br/> <table border="0" bordercolor="#FFFFFF" bgcolor="#FFFFFF" bordertype="1" style="margin-bottom:4px;margin-top:12px" align=center width=100%> <tr> <td width=50% class="phigh">CURRENCY 货币</td> <td width=50% class="phigh"><b><u></u></b></td> </tr> <tr> <td width=50% class="phigh">FACE AMOUNT 券面总额</td> <td width=50% class="phigh"></td> </tr> <tr> <td width=50% class="phigh">DIRTY PRICE 全价</td> <td width=50% class="phigh"></td> </tr> <tr> <td width=50% class="phigh">CLEAN PRICE 净价</td> <td width=50% class="phigh"></td> </tr> <tr> <td width=50% class="phigh">YIELD 收益率</td> <td width=50% class="phigh"></td> </tr> <tr> <td width=50% class="phigh">DELIVERY DATE 交割日</td> <td width=50% class="phigh">2015-10-27</td> </tr> <tr> <td width=50% class="phigh">SETTLEMENT TYPE 结算方式</td> <td width=50% class="phigh"></td> </tr> <tr> <td width=50% class="phigh">ISSUE CODE 债券代码</td> <td width=50% class="phigh">119175.SZ</td> </tr> <tr> <td width=50% class="phigh">ISSUE 债券名称</td> <td width=50% class="phigh">科慧04</td> </tr> <tr> <td width=50% class="phigh">MATURITY DATE 债券到期日</td> <td width=50% class="phigh">2019-04-23</td> </tr> <tr> <td width=50% class="phigh">SPECIAL DETAILS 特别细节</td> <td width=50% class="phigh"></td> </tr> </table> </body></html>
