Ability to Insert IDs into XML Tags about docxtemplater

[edi9999]

Hello,

I remember someone doing something very similar a few years back. (Maybe it was you ?). I could'n t find whether it was on a github issue or per email.

I think the way he did it at the time was, before passing the data to docxtemplater, he would open the word/document.xml, and add unique ids to each <w:t> tag.

Then you could generate your docx from that same zip file.

Something like this (untested code, but likely should work) :

const zip = new JSZip(buf);
const text = zip.file("word/document.xml").asText();
const { DOMParser, XMLSerializer } = require('@xmldom/xmldom')
const document = new DOMParser().parseFromString(text, "text/xml");
const textTags = document.getElementsByTagName("w:t");
let trackedId = 1;
for (let i = 0, len = textTags.length; i < len; i++) {
	const textTag = textTags[i];
	textTag.setAttribute("_trackedId", trackedId++)
}
const newText = new XMLSerializer().serializeToString(document);
zip.file("word/document.xml", newText);
const doc = new Docxtemplater(zip, { paragraphLoop: true, linebreaks: true });
doc.render({
     first_name: "John",
});

I'm not exactly sure how you then convert your XML to HTML and keep the tags, if you have more insights, please post them here so that future users can also benefit from this !
