I have an SVG object like that:
<svg class="class-a color-green marker" .../>
In Playwright I want to get an exact list of classes of this element. I use the following code to locate it:
page.locator(".status-marker").first
The node is located properly, but when I call evaluate("node => node.className") on it, I get an empty dict, like the locator stripped all information about classes at all.
In general, it doesn't matter how I get the handle of this element, I always get an empty dict on evaluate("node => node.className").
Calling page.locator(".status-marker").first.is_visible() returns True, so the object exists.
Also if I run page.locator(".status-marker").first.evaluate("node => node.outerHTML") I'll get the full HTML of that node, that does have the class name included. I could parse that, but it would be pretty clunky solution.
I found out that I could use expect(locator).to_have_class(), but If the node has more than one class I need to put all of them for it to pass, when I care only on one of them (the other classes are dynamically generated, so I can't even know about them during tests).
Edit:
Here's some additional sample:
assert page.locator(".marker").first.evaluate("node => node.className") == {}
expect(page.locator(".marker").first).to_have_class("text-green-1")
The first assert passes - the evaluate("node => node.className") returns an empty dict. The expect() fails with the following error:
AssertionError: Locator expected to have class 'text-green-1'
E Actual value: inline pr-2 text-green-1 marker svelte-fa s-z-WEjw8Gh1FG
I've found a way to reproduce it (it happens to me in font awesome plugin for svelte):
def test_svelte_fa(page):
page.goto("https://cweili.github.io/svelte-fa/")
item = page.locator(".svelte-fa").first
assert item.is_visible()
assert "svelte-fa" in item.evaluate("node => node.className")
In your example, the className of an SVG is an SVGAnimatedString object. Which is not serializable.
If you do JSON.stringify($('.svelte-fa').className) on the browser, you will see that the value is {}.
Values returned by the evaluate function needs to be serializable.

I'm currently teaching myself the Dart language, and my first app doesn't seem to be working right. Here's the code that's causing trouble:
usrLoc = int.parse(query("#txtLoc").text);
When I try to run the app, it opens fine, but when I click the button that triggers this (and three other similar parses), the debugger stops and tells me "Source not found" for int._native_parse(), int._parse(), and int.parse().
Any help would be greatly appreciated.
The text property for the specified element #txtLoc returns an empty string.
The parse method requires that:
The source must be a non-empty sequence of base- radix digits, optionally prefixed with a minus or plus sign ('-' or '+').
You can specify an onError named argument in your call to parse, which takes a callback that handles the invalid input. E.g., if you want the parse call to return the value 42 for all invalid input, you can do this:
usrLoc = int.parse(query("#txtLoc").text, onError: (val) => 42);
If you really expect the element to have some text, you can store the result of query("#txtLoc").text into a separate variable and verify the value. It would also be interesting to check what the real element type is or which tag is marked with id #txtLoc.
If you want to get the content of an input element, you should use the value property instead of text:
query("#txtLoc").value
I have a Map in Dart (originally loaded from JSON) that looks something like this:
somevar = {
'Title': 'Some object',
'items': [{'title': 'Item 1 Title'}, {'title': 'Item 2 Title'}]
}
For some reason somevar['items'] doesn't behave quite like a list.
I get Exception: NoSuchMethodError : method not found: 'iterator' if I attempt to iterate over the list.
I also get a similar error if I try somevar['items'].length
If I manually load this "list" like this: someList = new List(somevar['items']); then it works as expected.
Any idea why this is that case, and what I'm doing wrong? For me the natural expectation would be that a "list" parsed from JSON will behave exactly like the List() object.
Never mind, seems that I had a deeper issue in my code that cause my somevar variable to be null (even though it should have the map.
Anyway, I'm marking this as solved for now so not to waste anyone's time.
Hitting my wall here...
I've got the following data where a Primary Employee may have multiple dependents. I need to create a function that will match the Employee's SSN (ab:SSN) against the Dependent_SSN and determine if one of them is a 'Spouse'. If so, then we'll return the Dependent_SSN of the 'Spouse'.
If not, we'll move on and return the next non-'Spouse' Dependent_SSN.
I'm trying to create a function as I think I'll need this more than once. The code snippet resides inside of an existing template that is doing other looping functionality.
I've tried this but Oxygen returns an error:
<xsl:function name="ab:PQB">
<xsl:param name="EE_SSN">
</xsl:param>
<xsl:for-each select="/ab:Report_Data/ab:Report_Entry[ab:Employee_ID=$EE_SSN]/ab:Report_Data/ab:Report_Entry[ab:Employee_ID=$EE_SSN]ab:dependents/ab:Dependent_SSN">
</xsl:for-each>
The Error returned is :
"Engine name: Saxon-PE 9.3.0.5
Severity: fatal
Description: Unexpected token name "wd:dependents" beyond end of expression"
I know I need to test the higher level SSN against looping through the dependents, but like I said "I'm against my wall" :)
Data is here:
<ab:Report_Entry>
<ab:SSN>888881006</ab:SSN>
<ab:Last_Name>Smith</ab:Last_Name>
<ab:First_Name>Kimberly</ab:First_Name>
<ab:dependents>
<ab:Dependent_SSN>888881009</ab:Dependent_SSN>
<ab:Relation ab:Descriptor="Spouse">
</ab:Relation>
</ab:dependents>
<ab:dependents>
<ab:Dependent_SSN>888881004</ab:Dependent_SSN>
<ab:Relation ab:Descriptor="Child">
</ab:Relation>
</ab:dependents>
<ab:dependents>
<ab:Dependent_SSN>888881003</ab:Dependent_SSN>
<ab:Relation ab:Descriptor="Child">
<ab:ID ab:type="Related_Person_Relationship_ID">Child</ab:ID>
</ab:Relation>
</ab:dependents>
<ab:dependents>
<ab:Dependent_SSN>888881001</ab:Dependent_SSN>
<ab:Dependent_ID>1032D-4</ab:Dependent_ID>
<ab:Relation ab:Descriptor="Child">
<ab:ID ab:type="Related_Person_Relationship_ID">Child</ab:ID>
</ab:Relation>
</ab:dependents>
</ab:Report_Entry>
Thank you to any advice!
You might want to define the type of the input parameter and the type of the function result and then you should write a function body returning a value of that type. Currently your description sounds rather procedural, that is not going to work with XSLT/XPath.
As for the error, I think in the path /ab:Report_Data/ab:Report_Entry[ab:Employee_ID=$EE_SSN]/ab:Report_Data/ab:Report_Entry[ab:Employee_ID=$EE_SSN]ab:dependents/ab:Dependent_SSN you need one more slash /ab:Report_Data/ab:Report_Entry[ab:Employee_ID=$EE_SSN]/ab:Report_Data/ab:Report_Entry[ab:Employee_ID=$EE_SSN]/ab:dependents/ab:Dependent_SSN to have a syntactically correct path. That should avoid the syntax error you get but is not likely to return the result you want.
My understanding is that inside of a coffeescript function, "this" or "#" is equal to "window" (at least in the context of Rails). Why is it then that I can get this code to work:
window.googletag = window.googletag or {}
window.googletag.cmd = window.googletag.cmd or []
window.googletag.cmd.push ->
window.googletag.defineSlot('/1003175/ad-name-here', [336, 280], 'div-gpt-ad-1349373630997-0').addService(window.googletag.pubads())
window.googletag.pubads().enableSingleRequest()
window.googletag.enableServices()
but not this code
#googletag = #googletag or {}
#googletag.cmd = #googletag.cmd or []
#googletag.cmd.push ->
#googletag.defineSlot('/1003175/ad-name-here', [336, 280], 'div-gpt-ad-1349373630997-0').addService(#googletag.pubads())
#googletag.pubads().enableSingleRequest()
#googletag.enableServices()
When I place in my code alert(# == window) I get true.. if they are the same then why would one work but not the other? Is there not a more graceful way to write this code then appending window to every instance of the word googletag?
In coffeescript, the # is equivalent to this, but the value of this is dependent on your current scope within the code. In your example, alert(# == window) returns true because in that context this is the window. But when you use it in another context, for example inside a function definition (#googletag.cmd.push -> ...) then it will get the context of whatever scope that function is called from.
In the end this is not a coffeescript issue but a Javascript issue. I'd recommend reading up a bit more on this, it's a somewhat confusing concept at first.
Here's one article that helped me understand the concept better: http://yehudakatz.com/2011/08/11/understanding-javascript-function-invocation-and-this/
I have a quick question. I am currently writing a Nokogiri/Ruby script and have the following code:
fullId = doc.xpath("/success/data/annotatorResultBean/annotations/annotationBean/concept/fullId")
fullId.each do |e|
e = e.to_s()
g.write(e + "\n")
end
This spits out the following text:
<fullId>D001792</fullId>
<fullId>D001792</fullId>
<fullId>D001792</fullId>
<fullId>D008715</fullId>
I wanted the just the numbers text in between the "< fullid>" saved, without the < fullId>,< /fullId> markup. What am I missing?

I think you want to use the text() accessor (which returns the child text values), rather than to_s() (which serializes the entire node, as you see here).
I'm not sure what the g object you're calling write on is, but the following code should give you an array containing all of the text in the fullId nodes:
doc.xpath(your_xpath).map {|e| e.text}
