playwright-xpath

a playwright custom selector engine for xpath 3.1 using fontoxpath

installation

npm install playwright-xpath

usage

import xpath3 from 'playwright-xpath'

selectors.register('xpath3', xpath3)
;(async () => {
    await page.setContent('<button>Click me</button>')

    // (the starts-with function is only available in xpath 2 and above)
    await page.click("xpath3=//button[starts-with(., 'Click')]")

features

xpath 3.1

currently, all browsers (and playwright) only support xpath 1.0. however there are many useful features that were added in xpath 2 and above which are now supported thanks to fontoxpath

svg support

due to how xml namespaces work, svg elements do not work when using xpath on html. to work around this, the playwright-xpath selector engine allows you to specify the svg prefix:

await page.setContent('<svg><text>asdf</text></svg>')
await page.waitForSelector('xpath=//svg/text') // doesn't work
await page.waitForSelector('xpath3=//svg/text') // doesn't work
await page.waitForSelector('xpath=//svg:svg/svg:text') // doesn't work
await page.waitForSelector('xpath3=//svg:svg/svg:text') // works
