When I try to install node-red-contrib-xml-validate/xml-validate I get the following error:

```auto
8 Feb 08:39:30 - [warn] ------------------------------------------------------
8 Feb 08:39:30 - [warn] [node-red-contrib-xml-validate/xml-validate] Error: Cannot find module '/usr/local/lib/node_modules/node-red/red/red'
Require stack:

- /usr/local/lib/node_modules/node-red/red.js

```

I tried both ways from the palette in node-red ui and from the with ```  
npm install node-red-contrib-xml-validate

```auto

I installed java, as it as a dependency on it.

I do have all files listed in the require stack log...
```

As [node-red-contrib-xml-validate](https://github.com/alessh/node-red-contrib-xml-validate) was last updated 6 years, 1 month ago and there has been no response to the single issue raised last year, I think you will have to assume this node is abandoned.

You could try adding [libxml-xsd](https://www.npmjs.com/package/libxml-xsd) to the setup tab on a function node and use something like this...

read file node --\> function --\> debug

function code...

```auto
var schema = libxmlXsd.parse(msg.payload); //schemaString loaded from file
var validationErrors = schema.validate(msg.documentString); //documentString passed in msg
msg.payload = validationErrors;
return msg; 

```
