python - elementtree.parse() 不打开文件 open() 将

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。我无法让元素树打开我想要的文件。但是，我可以使用 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()

将代码更新为此，对于我收到的评论：

    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")
