java - Selenium WebDriver: clicking on elements within an SVG using XPath

Question

I have an SVG object with a few circle and rectangle elements. Using webdriver, I can click on the main svg object, but not any of the elements within it. The problem only seems to be with clicking (or any mouse interaction), as I can use getAttribute() to return the value(s) of width, ID, x/y, text, etc, for anything under it.

Here is an example of the HTML:

    <div id="canvas">
        <svg height="840" version="1.1" width="757" xmlns="http://www.w3.org/2000/svg" style="overflow: hidden; position: relative;">
            <image x="0" y="0" width="757" height="840" preserveAspectRatio="none">
            <circle cx="272.34" cy="132.14">
            <rect x="241.47" y="139.23">
            <text style="text-anchor: middle; x="272.47" y="144.11">
        </svg>
    </div>

And an example of WebDriver trying to right click a rectangle element (and failing):

    WebElement mapObject = driver.findElement(By.xpath("//*[name()='svg']/*[name()='rect']"));
    Actions builder = new Actions(driver);
    builder.contextClick(mapObject).perform();

But this works and returns a value:

    driver.findElement(By.xpath("//*[name()='svg']/*[name()='rect']")).getAttribute("x");    

When WebDriver errors, it's usually this:

    org.openqa.selenium.WebDriverException: '[JavaScript Error: "a.scrollIntoView is not a function" {file: "file:///var/folders/sm/jngvd6s97ldb916b7h25d57r0000gn/T/anonymous490577185394048506webdriver-profile/extensions/[email protected]/components/synthetic_mouse.js" line: 8544}]' when calling method: [wdIMouse::move]

I've spent some time researching this and it seems to be a somewhat common issue with Selenium and SVGs, however I'm wondering if there is a workaround. The only solutions I've found are interacting with the SVG itself, which I can already do.

I'm using Selenium 2.28 (and tried 2.29) w/ Java + Firefox 17.

Any ideas greatly appreciated.

Answer 1

For anyone interested, I solved this in the following ways:

1) I was originally testing this on OSX with Firefox 17 and Selenium 2.28/29, but figured out it only works (at least for me) on Windows with Firefox 18 and Selenium 2.29

2) interacting with SVGs with the standard:

driver.findElement(By.xpath(YOUR XPATH)).click();

doesn't work. You need to use Actions.

3) to interact with SVG objects, the following XPath works:

"/*[name()='svg']/*[name()='SVG OBJECT']";

The SVG object being anything under the SVG element (e.g. circle, rect, text, etc).

An example of clicking an SVG object:

WebElement svgObject = driver.findElement(By.xpath(YOUR XPATH));
Actions builder = new Actions(driver);
builder.click(svgObject).build().perform();

Note: you need to call the path inside the click() function; using:

moveToElement(YOUR XPATH).click().build().perform();

doesn't work.
