// Turns out IE11 doesn't support XPath, so not using `./xpathBrowser` for browsers.
// https://github.com/catamphetamine/read-excel-file/issues/26
// The inclusion of `xpath` package in `./xpathNode`
// increases the bundle size by about 100 kilobytes.
// IE11 is a wide-spread browser and it's unlikely that
// anyone would ignore it for now.
// There could be a separate export `read-excel-file/ie11`
// for using `./xpathNode` instead of `./xpathBrowser`
// but this library has been migrated to not using `xpath` anyway.
// This code is just alternative/historical now, it seems.
