Get version from manifest.xml CEP Extension

[Guest]

I have a small application developed with CEP. Is there a way to get the version from manifest.xml ? I make some checks if the version is smaller then version from my server if it is true I show some message for upgrade to a new version.
I avoid to read from file system because it's some problem with os between mac and windows and it appear some bugs, is there another solution for?

Don't you hardcode the version number in your app?

It is hardcoded but not in js or jsx file it is hardcoded in manifest.xml file.
I think a good practice is to add/modify version in manifest.xml like:

<ExtensionManifest ExtensionBundleId="examplePanel" ExtensionBundleName="examplePanel" ExtensionBundleVersion="1.0.0" Version="7.0">
<ExtensionList>
<Extension Id="examplePanel.extension" Version="1.0"/>
</ExtensionList>

I wana get this ExtensioBundleVersion or Version from manifest.xml.

It's not the right pattern but I made a function which the read manifest.xml and get the ExtensionBundleVersion attribute from file. 

function getPluginVersion() {
    const fs = require('fs');
    const path = csInterface.getSystemPath(SystemPath.EXTENSION);
    const data = fs.readFileSync(`${path}/CSXS/manifest.xml`);

    if (!data) {
        needNewVersion = true;

        return;
    }

    if (window.DOMParser) {
        const parser = new DOMParser();
        const xmlDoc = parser.parseFromString(data.toString(), 'text/xml');
        const children = xmlDoc.children;

        for (let i = 0; i <= children.length; i++) {
            if (children[i] && children[i].getAttribute('ExtensionBundleVersion')) {
                version = children[i].getAttribute('ExtensionBundleVersion');
            }
        }
    }
}

I was not familiar with Node.js, so my mentor taught me this.

function getBundleVersion(){
    var csi = new CSInterface();
    var pth = csi.getExtensions([csi.getExtensionID()])[0].basePath + "/CSXS/manifest.xml";
    var data = window.cep.fs.readFile(pth, cep.encoding.utf8).data;
    var ver = data.match(/(?<=ExtensionBundleVersion\=")[\d\.]+(?=")/);
    if(ver){
        return ver[0];
    }
}
