getting cs1010(Newline in constant) exception on driver.FindElement(By.XPath) lines

Question

Both backslash and apostrophe are common characters used in XPath. Perhaps this always happens, and I only see it now because I added a watch to the line, but it seems every FindElement line is throwing this exception

One of the lines throwing this error is ...

if (loadedPage.FindElements(By.XPath("//div[@class='field signature capture']")).Count != 0)

I expect the proper XPath syntax to not cause an exception.

HTML ...

                    <div class='loaded page' id='page_0' style='height:1030.0px;width:796.0px;background-image:url(/packages/INDle9T1Y4PGRpKDir2KZxuTWoY=/documents/26a85bc2-d735-4135-ad15-d09ce11699f1/pages/0?v=322608);'>
                      <!-- - cssclass  = "field role_#{approval.role.id} #{field.type} #{field.subtype} #{approval.accepted? ? 'accepted' : ''}" -->
                      <div approval='hc1T31A6E0I6' class='field signature capture ' esl_id='_ircL7s98umMX' id='ircL7s98umMX' style='height:55.0px;left:468.0px;top:369.0px;width:220.0px;' tabindex='1' title='Click on the yellow box to capture your handwritten signature.'>

                        </div>
                      </div>

Answer 1

To check your Html i can see there is white space at end end of the class attribute.

Instead of this.

if (loadedPage.FindElements(By.XPath("//div[@class='field signature capture']")).Count != 0)

Try this.

if (loadedPage.FindElements(By.XPath("//div[contains(@class,'field signature capture')]")).Count != 0)

OR

if (loadedPage.FindElements(By.XPath("//div[normalize-space(@class)='field signature capture']")).Count != 0)

Answer 2

While this did not address the initial question regarding the syntax of FindElement and it causing the CS1010: Newline in Constant exception, this did help get me past the issue that was blocking me.
