This saves you the hassle of starting up a desktop editor and installing a plugin. Be aware that your XML config files might contain sensitive data, do not use online validation tools if this is the case. The UX is highly intuitive and a desktop editor like VSCode gives you a secure location to run verifications on XML files that contain confidential data.
In this post I quickly run through the XML validation rules and what a well formed XML document needs to be valid, as well as 7 tools, both desktop and online, to verify validity and how they compare. The validators I cover here verifies the XML syntax. An XML document also has a structure. This is the extensible part. In order to communicate data using XML the send and receiver of the document need to understand the structure of the document. They need to agree on what elements will appear in the document and what they mean.
After the prolog, a valid document must have only one root element. This element is the parent element of all elements in the document.
An XML element is made up of a start tag and an end tag with content in the middle. Here are some examples. Closing tags have a forward slash before the name to identify them as closing tags. The above element is self contained, because it does not enclose any data or further elements it can be closed with the shorthand notation of adding the slash to the end of the name.
Schemas can also be found in the following additional locations when the schema has a non-empty target namespace:. When editing an XSLT file, the xslt. Validation errors are shown as blue wavy underlines. Errors from the XSLT compiler are shown as red wavy underlines.
When editing an XML Schema file, the xsdschema. Any compilation errors are also shown with red wavy underlines. DTD processing limits the number of entity references by default to 10, references and can accomodate most XML schemas.
The error message in Visual Studio may read "Exceeded entity references limit for filename". Just by having a device that runs on Windows OS, users can make the most of this tool.
