Compare XML ignoring order of child elements
提问by Andrew Garrison
Does anybody know of a tool that will compare two XML documents. Belay that mocking… there's more. I need something that will make sure each node in file 1 is also in file 2 regardless of order. I thought XML Spy would do it with the Ignore Order of Child Nodes option but it didn't. The following would be considered the same:
有谁知道比较两个 XML 文档的工具。保护那个嘲讽……还有更多。我需要一些东西来确保文件 1 中的每个节点也在文件 2 中，无论顺序如何。我认为 XML Spy 会使用忽略子节点顺序选项来实现，但事实并非如此。以下情况将被视为相同：
<Node>
<Child name="Alpha"/>
<Child name="Beta"/>
<Child name="Charlie"/>
</Node>
<Node>
<Child name="Beta"/>
<Child name="Charlie"/>
<Child name="Alpha"/>
</Node>

You might want to google for "XML diff tool", which will give you more than adequate results. One of them is OxygenXml, a tool I frequently use. You can also try Microsofts XML Diff and Patch Tool.
您可能想在 google 上搜索“ XML diff tool”，它会给您足够的结果。其中之一是OxygenXml，这是我经常使用的工具。你也可以试试微软的XML Diff and Patch Tool。
Good Luck.
祝你好运。

I wrote a simple python tool for this called xmldiffs:
我为此编写了一个简单的 python 工具xmldiffs：
Compare two XML files, ignoring element and attribute order.
Usage:
xmldiffs [OPTION] FILE1 FILE2Any extra options are passed to the
diffcommand.
比较两个 XML 文件，忽略元素和属性顺序。
用法：
xmldiffs [OPTION] FILE1 FILE2任何额外的选项都会传递给
diff命令。

With Beyond Compareyou can use in the File Formats-Settings the XML SortConversion. With this option the XML children will be sorted before the diff.
使用Beyond Compare，您可以在File Formats-Settings 中使用XML Sort转换。使用此选项，XML 子项将在差异之前排序。
A trial / portable version of Beyond Compare is available.
可以使用Beyond Compare 的试用版/便携版。

I had a similar need this evening, and couldn't find something that fit my requirements.
今晚我有类似的需求，但找不到符合我要求的东西。
My workaround was to sort the two XML files I wanted to diff, sorting alphabetically by the element name. Once they were both in a consistent order, I could diff the two sorted files using a regular visual diff tool.
我的解决方法是对我想要比较的两个 XML 文件进行排序，按元素名称的字母顺序排序。一旦它们的顺序一致，我就可以使用常规的可视化差异工具比较这两个排序的文件。
If this approach sounds useful to anyone else, I've shared the python script I wrote to do the sorting at http://dalelane.co.uk/blog/?p=3225
如果这种方法对其他人有用，我已经在http://dalelane.co.uk/blog/?p=3225 上分享了我编写的用于排序的 python 脚本

Here is a diff solution using SWI-Prolog
这是使用 SWI-Prolog 的差异解决方案
:- use_module(library(xpath)).
load_trees(XmlRoot1, XmlRoot2) :-
load_xml('./xml_source_1.xml', XmlRoot1, _),
load_xml('./xml_source_2.xml', XmlRoot2, _).
find_differences(Reference, Root1, Root2) :-
xpath(Root1, //'Child'(@name=Name), Node),
not(xpath(Root2, //'Child'(@name=Name), Node)),
writeln([Reference, Name, Node]).
diff :-
load_trees(Root1, Root2),
(find_differences('1', Root1, Root2) ; find_differences('2', Root2, Root1)).
Prolog will unify the Name variable to match nodes from file 1 and file 2. The unification on the Node variable does the "diff" detection.
Prolog 将统一 Name 变量以匹配来自文件 1 和文件 2 的节点。 Node 变量上的统一进行“差异”检测。
Here's some sample output below:
下面是一些示例输出：
% file 1 and file 2 have no differences
?- diff.
false.
% "Alpha" was updated in file 2
?- diff.
[1,Alpha,element(Child,[name=Alpha],[])]
[2,Alpha,element(Child,[name=Alpha,age=7],[])]
false.

With C# You could do this and afterwards compare it with any diff tool.
使用 C#，您可以执行此操作，然后将其与任何差异工具进行比较。
public void Run()
{
LoadSortAndSave(@".. first file ..");
LoadSortAndSave(@".. second file ..");
}
public void LoadSortAndSave(String path)
{
var xdoc = XDocument.Load(path);
SortXml(xdoc.Root);
File.WriteAllText(path + ".sorted", xdoc.ToString());
}
private void SortXml(XContainer parent)
{
var elements = parent.Elements()
.OrderBy(e => e.Name.LocalName)
.ToArray();
Array.ForEach(elements, e => e.Remove());
foreach (var element in elements)
{
parent.Add(element);
SortXml(element);
}
}

Wrote a simple java program to do so. Stored two XML's being compared in a HashMap, with key as XPath of element(including text value of element) and value as number of occurrences of that element. then compared two HashMap's for both keyset and values.
写了一个简单的java程序来做到这一点。将两个 XML 存储在一个 HashMap 中进行比较，键是元素的 XPath（包括元素的文本值），值是该元素的出现次数。然后比较两个 HashMap 的键集和值。
/**
* creates a map of elements with text values and no nested nodes.
* Here Key of the map is XPATH of element concatenated with the text value of element, value of the element is number of occurrences of that element.
*
* @param xmlContent
* @return
* @throws ParserConfigurationException
* @throws SAXException
* @throws IOException
*/
/** * 创建具有文本值且没有嵌套节点的元素映射。
* 这里映射的Key是元素的XPATH与元素的文本值连接，元素的值是该元素出现的次数。
* * @param xmlContent * @return * @throws ParserConfigurationException * @throws SAXException * @throws IOException */
private static Map<String, Long> getMapOfElementsOfXML(String xmlContent)
throws ParserConfigurationException, SAXException, IOException {
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setValidating(false);
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc1 = db.parse(new ByteArrayInputStream(xmlContent.getBytes()));
NodeList entries = doc1.getElementsByTagName("*");
Map<String, Long> mapElements = new HashMap<>();
for (int i = 0; i < entries.getLength(); i++) {
Element element = (Element) entries.item(i);
if (element.getChildNodes().getLength() == 1&&element.getTextContent()!=null) {
final String elementWithXPathAndValue = getXPath(element.getParentNode())
+ "/"
+ element.getParentNode().getNodeName()
+ "/"
+ element.getTagName()
+ "/"
+ element.getTextContent();
Long countValue = mapElements.get(elementWithXPathAndValue);
if (countValue == null) {
countValue = Long.valueOf(0l);
} else {
++countValue;
}
mapElements.put(elementWithXPathAndValue, countValue);
}
}
return mapElements;
}
static String getXPath(Node node) {
Node parent = node.getParentNode();
if (parent == null) {
return "";
}
return getXPath(parent) + "/" + parent.getNodeName();
}

i recently gave a similar answer here (Open source command line tool for Linux to diff XML files ignoring element order), but i'll provide more detail...
我最近在这里给出了类似的答案（Linux 的开源命令行工具来区分 XML 文件忽略元素顺序），但我将提供更多详细信息...
if you write a program to walk the two trees together, you can customize the logic for identifying "matches" between the trees, and also for handling nodes that don't match. here is an example in xslt 2.0 (sorry it's so long):
如果您编写一个程序来一起遍历两棵树，您可以自定义用于识别树之间“匹配”以及处理不匹配节点的逻辑。这是 xslt 2.0 中的一个示例（抱歉它太长了）：
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:set="http://exslt.org/sets"
xmlns:primary="primary"
xmlns:control="control"
xmlns:util="util"
exclude-result-prefixes="xsl xs set primary control">
<!-- xml diff tool
import this stylesheet from another and call the "compare" template with two args:
primary: the root of the primary tree to submit to comparison
control: the root of the control tree to compare against
the two trees will be walked together. the primary tree will be walked in document order, matching elements
and attributes from the control tree along the way, building a tree of common content, with appendages
containing primary and control only content. that tree will then be used to generate the diff.
the process of matching involves finding, for an element or attribute in the primary tree, the
equivalent element or attribute in the control tree, *at the same level*, and *regardless of ordering*.
matching logic is encoded as templates with mode="find-match", providing a hook to wire in specific
matching logic for particular elements or attributes. for example, an element may "match" based on an
@id attribute value, irrespective of element ordering; encode this in a mode="find-match" template.
the treatment of diffs is encoded as templates with mode="primary-only" and "control-only", providing
hooks for alternate behavior upon encountering differences.

with the stylesheet as is, the following is the output when applied to the example:
使用样式表，以下是应用于示例时的输出：
<Node>
<Child
++++++++<!-- ... -->

<Child

--------<!-- ... -->
- name="Charlie">

<Child
++++++++<!-- ... -->
+ name="Charlie"
--------<!-- ... -->
- name="Alpha">

</Node>
but, if you add this custom template:
但是，如果您添加此自定义模板：
<xsl:template match="Child" mode="find-match" as="element()?">
<xsl:param name="candidates" as="element()*"/>
<xsl:sequence select="$candidates[@name = current()/@name][1]"/>
</xsl:template>
which says to match a Childelement based on its @nameattribute, then you get no output (meaning there is no diff).
它说根据Child元素的@name属性匹配元素，然后你没有输出（意味着没有差异）。
