User guide

This small tool allows to compare two XML data structures, and visualize the diff.

Copy and paste, drag and drop a XML file or directly type in the editors above, and then click on "Compare" button they will be compared if the two XML are valids.
You can also click on "load XML from URL" button to load your XML data from a URL (Must be https).
You can also click on "Browse XML file" button to load your XML data from a local file.

You can also directly compare two XML files by specifying their urls in the GET parameters url1 and url2.
Example: https://extendsclass.com/xml-diff.html?url1=https://extendsclass.com/mock/rest/3b3aea6de65f5bd7576a1079bf9b6ec5/sample1.xml&url2=https://extendsclass.com/mock/rest/3b3aea6de65f5bd7576a1079bf9b6ec5/sample2.xml

Then you can visualize the differences between the two XML documents. It highlights the elements which are different:

Different value between the two XML: highlight in red color
Element only presents in a single XML: highlight in yellow or orange color

You can navigate to next / previous difference:

Clicks on "Next diff" button in order to go to the next difference
Clicks on "Previous diff" button in order to go to the previous difference

Online XML compare tool
It can be helpful to compare XML documents, unfortunately it can be difficult to see the differences between large XML documents. This free online tool will allows you to do this easily.
XML diff tool makes a semantic comparison, it compares every attribute–value pairs of objects. It compares each node according to their position in the arrays. It sorts and formats the XML strings in order to find the semantic differences instead of just the text ones.
Note: For mixed-content elements (containing character data and elements), it compares the elements two by two according to their order (instead of by type) in the parent element.
Mixed content exemple:

XML vs JSON

Extensible Markup Language (XML) is a markup language that uses human-readable text to transmit data. This format is a W3C Recommendation.

JSON and XML are similar on many specificities:

Both can be used to receive / send data from / to a web server.
Both can be used by programming languages
...

JSON has advantages over XML: JSON is shorter and it is therefore quicker to read and write.

Despite the progress of using the json format, the xml format is still widely used.

Copied and pasted 36kB xml, and nothing happens. I checked the "Console". Browser: Chrome (the latest) Failed with the following in the console: Uncaught TypeError: Cannot read property 'length' of undefined at displayElement (xml-diff.html:401) at xml-diff.html:428 at NodeList.forEach (<anonymous>) at displayElement (xml-diff.html:421) at xml-diff.html:428 at NodeList.forEach (<anonymous>) at displayElement (xml-diff.html:421) at compareXML (xml-diff.html:180) at onChangeText (xml-diff.html:47) at codemirror.js:50

Nice tool.
It appears that tag names and the first attribute name get smashed together in the orange and yellow sections.

Hi,
just little bug: I compared two xml files and result was perfect (similar xml - same nodes but in different order), then I turn off my pc. Next day I restored my browser, this page was loaded, so I input two xml files again (same files as day before). This time comparing not working, files was evalueated as different (with red lines). There is probably some problem with reloading of page.

Great page though.
Have a nice day.

This is the only proper xml diff checker. Most comparison tools are just line by line comparators, which is useless if the xml is formatted into a single line or if the data is not in order.
A real xml comparison tool should compare randomly ordered data. This tool just does that.
