Question

在做javascript编程，现在需要合并2个xml文件为一个xml文件。然后直接读取合并后的xml文件~~拜托大家了 ~~

1.xml文件如下

<dataset>
<record>
<data>5</data>
<name>chen</name>
</record>
<record>
< data>4</data>
<name>sun</name>
</record>
</dataset>

2.xml文件如下

<dataset>
<record>
<sex>f</sex>
<collor>yellow</collor>
</record>
<record>
<sex>m</sex>
<collor>black</collor>
</record>
</dataset>

Answer 1

<button onclick="alert(xml.lookxml())" id=button1 name=button1>查看XML标签</button>
<hr>
添加节点：姓名：<input type=text id="name"> 内容：<input type=text id="content"> <input type=button value="添加XML节点" onclick="addnode()" id=button3 name=button3>
<hr>
xpath查询：<input type=text id="sql"><input value="xpath查询" type=button onclick="Ctable(oo('sql').value)" id=button4 name=button4>
<hr>
<div id=createTable></div>
