Question

尝试将XML文件解析为ElementTree：

>>> import xml.etree.cElementTree as ET
>>> tree = ET.ElementTree(file='D:\Temp\Slikvideo\JPEG\SV_4_1_mask\index.xml')

我收到以下错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Program Files\Anaconda2\lib\xml\etree\ElementTree.py", line 611, in __init__
    self.parse(file)
  File "<string>", line 38, in parse
ParseError: junk after document element: line 3, column 0

XML文件的开头如下：

<?xml version="1.0" encoding="UTF-8" ?>
<Version Writer="E:\d\src\Modules\SceneSerialization\src\mitkSceneIO.cpp" Revision="$Revision: 17055 $" FileVersion="1" />
<node UID="OBJECT_2016080819041580480127">
    <source UID="OBJECT_2016080819041550469454" />
    <data type="LabelSetImage" file="hfbaaa_Bolus.nrrd" />
    <properties file="sicaaa" />
</node>
<node UID="OBJECT_2016080819041512769572">
    <source UID="OBJECT_2016080819041598947781" />
    <data type="LabelSetImage" file="ifbaaa_Bolus.nrrd" />
    <properties file="ticaaa" />
</node>

后面跟着更多的节点。

我在第3行第0列看不到任何垃圾？我认为必须有另一个错误原因。

.xml文件由外部软件MITK生成，所以我认为应该没问题。

使用Win 7,64位，VS2015，Anaconda

正如@Matthias Wiehl所说，ElementTree只需要一个根节点，而不是格式良好的XML，应该在其原点修复。作为一种解决方法，您可以在文档中添加假根节点。

var version = "?v=0.0.1";
// array of URL's to request
var links = ["app/css/normalize.min.css", "app/css/bootstrap.min.css", ..];

$.holdReady(true);

$.when.apply($, $.map(links, function(path) {
  return new $.Deferred(function(d) {
               $("<link>", {href: path + version, rel: "stylesheet"})
               .appendTo("head").on("load", d.resolve);
             })
}))
.then(function() {
  $.holdReady(false)
});

$(document).ready(function() {
  // do stuff when all `<link>` elements have been appended to `<head>`
})

Answer 2

文档的根节点（Version）在第2行打开和。解析器不期望在根节点之后有任何节点。解决方案是删除关闭正斜杠。

Answer 3

尝试像这样修复文档。关闭末尾的version元素

<?xml version="1.0" encoding="UTF-8" ?>
<Version Writer="E:\d\src\Modules\SceneSerialization\src\mitkSceneIO.cpp" Revision="$Revision: 17055 $" FileVersion="1">
    <node UID="OBJECT_2016080819041580480127">
        <source UID="OBJECT_2016080819041550469454" />
        <data type="LabelSetImage" file="hfbaaa_Bolus.nrrd" />
        <properties file="sicaaa" />
    </node>
    <node UID="OBJECT_2016080819041512769572">
        <source UID="OBJECT_2016080819041598947781" />
        <data type="LabelSetImage" file="ifbaaa_Bolus.nrrd" />
        <properties file="ticaaa" />
    </node>
</Version>
