Re: Is there any way to assert line break sentences in selenium web driver.

[Tarun Kumar]

What text do you get when you use - ui-message-error-detail as element locator?

If you get extra spaces then you can trim them using xPath function normalize-space()

Hi,

I have to assert the expected error message with actual error message . But the error message in HTML source page has line break.

I have used assert like this :

assertEquals("The email is blank. Please enter an email!",driver.findElement(By.xpath(XXXXXXXX)).gettext());

Page Source : 

<span class="ui-message-error-detail">The email is blank.<br/>Please enter an email!</span>
                                

note : If there is no line break tags , I can assert it. But due to line break I couldn't do it..script failing.

Can anyone help me..

@Tarun,normalize-space() replaces leading and trailing spaces. But in the Span's text it has <br/> in the middle of the text. 

@Nax, you have to use new line character while asserting the text. For example, the below snippet should work -

assertEquals("The email is blank.\nPlease enter an email!",driver.findElement(By.xpath(XXXXXXXX)).gettext());

@sai -

from - http://www.w3.org/TR/xpath/

<quote>The normalize-space function returns the argument string with whitespace normalized by stripping leading and trailing whitespace and replacing sequences of whitespace characters by a single space. </quote>

[Lutfi Dughman]

here is how you work around the br

//SPAN[.='The email is blank.Please enter an email!']

<span class="ui-message-error-detail">The email is blank.<br/>Please enter an email!</span>

.. now obviously this xpath doesn't tell whether there  is a BR in the span or not, but at elast it allow you to assert the content.

note there is no tspace between the '.' and work 'please'

You should also be able to get the text in two distinct blocks:

 

//span/text()[1]

//span/text()[2]

Thanks Tarun.

' normalize-space ' function worked

I have used path with normalise-space = //*[normalize-space(@id)='user-msg']/span[2]

Thanks once again for all for replies..

Sorry Tarun.. It didn't worked. I was mistaken.

My path is //*[@id='user-msg']/span[2]

How can I use the 'normalise-space' function? 

Page source is :

<div id="user-msg" class="ui-message-error ui-widget ui-corner-all"><span class="ui-message-error-icon"></span><span class="ui-message-error-detail">The email is blank.<br/>Please enter an email!</span></div>

Please send me the solution ...

Since there is </br> tag I am having a second thought about normalize-space being of no use in your case.

Did you try lutfijd  and Mark's solution?

[Nax143]

When I tried lutfijd solution , I am getting following error:

The given selector //SPAN[='The email is blank.Please enter an email!'] is either invalid or does not result in a WebElement. The following error occurred:

     [java] [InvalidSelectorError] Unable to locate an element with the xpath expression //SPAN[='The email is blank.Please enter an email!'] because of the following error:

     [java] [Exception... "The expression is not a legal expression."  code: "51" nsresult: "0x805b0033 (NS_ERROR_DOM_INVALID_EXPRESSION_ERR)"  location: "file:///var/folders/km/95m9f3rs28jfp_649qzlvsl40000gn/T/anonymous5457794172896486930webdriver-profile/extensions/fxdr...@googlecode.com/components/driver_component.js Line: 2621"]

When I tried Mark solution , I am getting following error:

code i have tried :

//*[@id='user-msg']/span[2]/text()[1]"

 str1=driver.findElement(By.xpath("//[@id='user-msg']/span[2]/text()[1]")).getText();

str2 =driver.findElement(By.xpath("//[@id='pass-msg']span[2]/text()[2]")).getText();

assertEquals("The email is blank. Please enter an email!",str1+" "+str2);

Error :

The given selector //*[@id='user-msg']/span[2]/text()[1] is either invalid or does not result in a WebElement. The following error occurred:

     [java] [InvalidSelectorError] The result of the xpath expression "//*[@id='user-msg']/span[2]/text()[1]" is: [object Text]. It should be an element.

Guys, any other solutions or correct me if u have any other idea.

    

[Lutfi Dughman]

here is your problem:

you forgot the '.' before the equal sign

//SPAN[.='The email is blank.Please enter an email!']

Hmm, that’s valid XPath, looks like we may have a bug.

 

I’ll double check later today.

[Mark Collin]

It would seem I’m talking rubbish (obviously too late for me).  I got as far as raising it as:

 

http://code.google.com/p/selenium/issues/detail?id=4158

 

But then stepped back and had another good look at the error message and thought, “I’m being an idiot, did I ever really do this in WebDriver?  Or was it something I’ve done with Selenium RC a long time ago”.

 

And confirmed I’m talking rubbish on IRC:

 

<Ardesco> Hmm am I raising balls?

<Ardesco> http://code.google.com/p/selenium/issues/detail?id=4158

<Ardesco> I'm sure I used to be able to get WebElements this way, but I have a nasty feeling I'm getting my Selenium RC API locator startegies mixed up with WebDriver ones

<Dude-X> i never liked using text() in my xpath

<jarib> Ardesco: AFAIK using findElement() to find text nodes has never worked

<Dude-X> it works sometimes...

<Dude-X> actually hmm

<Dude-X> i always remove it when i find it :P

<Ardesco> I thought I had use it in the past, but now i'm doubting myself

<Ardesco> *used

<Ardesco> and I agree it's something to avoid if possible

<Dude-X> anyway use getText() on the element

<jarib> either improve the markup or just do getText().split("\n") on the span

<barancev> should wdSession.prototype.getWindow return the top window?

<Ardesco> feel free to close it

<Ardesco> and slap a muppet stamp on me

<Ardesco> :)

 

Should have confirmed it on IRC first really, silly me.

Hi lutfijd,

I tried with '.' before equal sign , but no use. throwing error.

Mark,

I tried split , but no use. 

Regards,

Venkat
