如何比较两个XML逻辑上是否一致？（要考虑空格问题和等价问题）

1.xml
<?xml version="1.0" encoding="UTF-8"?>
xsi:schemaLocation="http://mapservice.easymap.com EasyXML1.1.xsd">
<REQUEST>
<EXECUTE>
<INSERT tablename="table1">
<FIELDS>
<FIELD name="f1" value="sdf"/>
<FIELD name="f2" value="gggg"/>
</FIELDS>
</INSERT>
</EXECUTE>
</REQUEST>
2.xml
<?xml version="1.0" encoding="UTF-8"?>
xsi:schemaLocation="http://mapservice.easymap.com EasyXML1.1.xsd">
<REQUEST>
<EXECUTE>
<INSERT tablename="table1">
<FIELDS>
<FIELD name="f1" value="sdf"/>
<FIELD name="f2" value="gggg"/>
</FIELDS>
</INSERT>
</EXECUTE>
</REQUEST>

1. 没看出这两个xml有什么区别.
2. 如果要比较, 那就把xml解析到object, 然后比较object.

写错了
1.xml
<?xml version="1.0" encoding="UTF-8"?>
xsi:schemaLocation="http://mapservice.easymap.com EasyXML1.1.xsd">
<REQUEST>
<EXECUTE>
<INSERT tablename="table1">
<FIELDS>
<FIELD name="f1" value="sdf"/>
<FIELD name="f2" value="gggg"/>
</FIELDS>
</INSERT>
</EXECUTE>
</REQUEST>
2.xml

<?xml version="1.0" encoding="UTF-8"?>
xsi:schemaLocation="http://mapservice.easymap.com EasyXML1.1.xsd">
<REQUEST>
<EXECUTE>
<INSERT tablename="table2">
<FIELDS>
<FIELD name="f3" value="asd"/>
<FIELD name="f4" value="hhhh"/>
</FIELDS>
</INSERT>
</EXECUTE>
</REQUEST>

个人见解：先解析xml，然后对比元素的个数，子元素。属性。。
