python读xml中元素顺序问题

a.xml内容如下:
      </project>
<project name="asdf" branch="asfasdfas" naname="xiao xin" QD6="091010">
<componentList table="cpp">
<entry>ae </entry>
<entry>pl </entry>
<entry>pp </entry>
<entry>ps </entry>
<entry>sa </entry>
</componentList>
<componentList table="java">
</componentList>

</project>


相应的处理函数如下：

def GetexpectData(project,branch):
        global locList
        global cppcomponentss,componentReposityy;
        cppcomponentss= {}
        tree = ET.parse("a.xml")
        p = getByAttr(tree.findall("project"),"name",project)
        if p!=None:
                compList = getByAttr(p.findall("componentList"),"table","cpp")
                comps = compList.findall("expect")
                for each in comps:
        &
