Parsing node and changing the value

1

Hi,

I have a created a formula node in my schema.

formula : { 
    inline:true,
    group: "inline",
    selectable:true,
    attrs:{
        expression:""
    },
    toDOM(node){ 
        return ["formula",{expression: node.attrs.expression}, node.attrs.expression]
    },
    parseDOM:[{
        tag:"formula",
        getAttrs(dom){
            return {
              expression: dom.attributes.expression.value
            }
        }
    }]
}

My formula tag : <formula expression=“a+b”>a+b</formula>

So when i parse this tag is is possible to replace the “a+b” with other value?

I saw getContent option in parserule but im sure how it will work?

Your getAttrs function could process the attributes it returns. Since this node has no content getContent isn’t relevant.

marijn, I have a table schema in my editor.The rows in my table needs to be dynamic based on the data im getting from my backend. Is it possible to do it ? Can you point me any examples or documentation?

You can modify / generate the document. I can’t really spell out what to do in your specific use case because A) you only vaguely described it, and B) that’s not really my job
