elementtree.parse（）没有打开文件open（）会

Question

我正在尝试编写一个python脚本，它将打开一个XML文件添加一些元素，然后退出。我无法获取元素树来打开我想要的文件。我可以用open（）打开文件。示例代码

try:
    file = open(projectLocation + "\etc\config\struts-config.xml", 'r')
    print "oppenned file" #this will print
    tree = ET.parse(projectLocation + "\etc\config\struts-config.xml") #this fails
    print "oppenned xml"
except:
    print "could not open " + projectLocation + "\etc\config\struts-config.xml"
    sys.exit()

为我收到的评论更新代码：

    tree = ET.parse(projectLocation + "\etc\config\struts-config.xml")
    print "oppenned xml"

这给了我错误：

        Traceback (most recent call last):

    tree = ET.parse(projectLocation + "\etc\config\struts-config.xml")
