-- [求助]xml格式化为体
感谢大家留意到我的这个贴子，这是一个树型结构XML文件，比如：
a1a2a3->a3
|_a1a2->a3
|_a2->a3
<?xml version="1.0" encoding="ISO-8859-1" ?>
<ruletree dbid="nomBD">
<rule support="1" confidence="confident" specialisable="yes">
<leftside>a1a2a4</leftside>
<item>a3</item>
<rule support="1" confidence="confident" specialisable="yes">
<leftside>a1a2</leftside>
<item>a3</item>
<rule support="1" confidence="confident" specialisable="no">
<leftside>a2</leftside>
<item>a3</item>
</rule>
</rule>
<rule support="1" confidence="confident" specialisable="no">
<leftside>a1a4</leftside>
<item>a3</item>
</rule>
</rule>
<rule support="1" confidence="confident" specialisable="yes">
<leftside>a1a4a5</leftside>
<item>a3</item>
<rule support="1" confidence="confident" specialisable="no">
<leftside>a1a5</leftside>
<item>a3</item>
<rule support="1" confidence="confident" specialisable="no">
<leftside>a5</leftside>
<item>a3</item>
</rule>
</rule>
</rule>
</ruletree>
问题：当我想格式化rule的时候，里面还包含有两个rule，
<rule support="1" confidence="confident" specialisable="yes">
<leftside>a1a2a4</leftside>
<item>a3</item>
<rule support="1" confidence="confident" specialisable="yes">
<leftside>a1a2</leftside>
<item>a3</item>
<rule support="1" confidence="confident" specialisable="no">
<leftside>a2</leftside>
<item>a3</item>
</rule>
</rule>
请大家帮忙，如何格式化此XML？
