I have a nodeset in the variable my_nodeset
I'd like to remove the last node that was found.
Initially i expected this to work: my_nodeset.last.remove but it does not.
The only way I've found to remove the last item is with something like this:
my_nodeset.delete(my_nodeset.last)
Seems strange to me and i was wondering if there's a "correct" way to do it. Thanks!
It is not strange to me.
my_nodeset.last.remove means:
call Nodeset my_nodeset then go to its last Node member and call remove method (owned by last). You want to ask to a Node method to modify a NodeSet. That's semantically wrong to me.
my_nodeset.delete(my_nodeset.last) is how it should be.

I want to be able to block everything on a page but a picture.
Example: https://imgur.com/gallery/wJIyDIF
##||i.imgur.com/St95Jdv.jpg
imgur.com##.post-pad.left < this overrides the previous line, order doesn't matter.
Ideally I would love something like this:
imgur.com##html
##||i.imgur.com/St95Jdv.jpg
Or this:
imgur.com##html > body
##||i.imgur.com/St95Jdv.jpg
But no idea how to actually make it work
Pretty sure, it is not possible. Every matching element is blocked with its children. Indeed, where would the children even be placed if their parent is hidden?
Your best hope is to block all siblings of the element you wish to keep...
I have a certain XPATH-query which I use to get the height from a certain HTML-element which returns me perfectly the desired value when I execute it in Chrome via the XPath Helper-plugin.
//*/div[#class="BarChart"]/*[name()="svg"]/*[name()="svg"]/*[name()="g"]/*[name()="rect" and #class="bar bar1"]/#height
However, when I use the same query via the Get Element Attribute-keyword in the Robot Framework
Get Element Attribute//*/div[#class="BarChart"]/*[name()="svg"]/*[name()="svg"]/*[name()="g"]/*[name()="rect" and #class="bar bar1"]/#height
... then I got an InvalidSelectorException about this XPATH.
InvalidSelectorException: Message: u'invalid selector: Unable to locate an
element with the xpath expression `//*/div[#class="BarChart"]/*[name()="svg"]/*
[name()="svg"]/*[name()="g"]/*[name()="rect" and #class="bar bar1"]/`
So, the Robot Framework or Selenium removed the #-sign and everything after it. I thought it was an escape -problem and added and removed some slashes before the #height, but unsuccessful. I also tried to encapsulate the result of this query in the string()-command but this was also unsuccessful.
Does somebody has an idea to prevent my XPATH-query from getting broken?
It looks like you can't include the attribute axis in the XPath itself when you're using Robot. You need to retrieve the element by XPath, and then specify the attribute name outside that. It seems like the syntax is something like this:
Get Element Attribute xpath=(//*/div[#class="BarChart"]/*[name()="svg"]/*[name()="svg"]/*[name()="g"]/*[name()="rect" and #class="bar bar1"])#height
or perhaps (I've never used Robot):
Get Element Attribute xpath=(//*/div[#class="BarChart"]/*[name()="svg"]/*[name()="svg"]/*[name()="g"]/*[name()="rect" and #class="bar bar1"])[1]#height
This documentation says
attribute_locator consists of element locator followed by an # sign and attribute name, for example "element_id#class".
so I think what I've posted above is on the right track.
You are correct in your observation that the keyword seems to removes everything after the final #. More correctly, it uses the # to separate the element locator from the attribute name, and does this by splitting the string at that final # character.
No amount of escaping will solve the problem as the code isn't doing any parsing at this point. This is the exact code (as of this writing...) that performs that operation:
def _parse_attribute_locator(self, attribute_locator):
parts = attribute_locator.rpartition('#')
...
The simple solution is to drop that trailing slash, so your xpath will look like this:
//*/div[#class="BarChart"]/... and #class="bar bar1"]#height`
I am trying to quickly find a specific node using XPath but it seems my multiple predicates are not working. The div I need has a specific class, but there are 3 others that have it. I want to select the fourth one so I did the following:
//div[#class='myCLass' and 4]
However the "4" is being ignored. Any help? I am new to XPath.
Thanks.
If a xpath query returns a node set you can always use the [OFFSET] operator to access a certain element of it.
Use the following query to access the fourth element that matches the #class='myClass' predicate:
//div[#class='myCLass'][4]
#WilliamNarmontas answer might be an alternative to the syntax showed above.
Alternatively,
//div[#class='myCLass' and position()=4]
The accepted answer works correctly only if all of the div elements have the same parent. Otherwise use:
(//div[#class='myCLass'])[4]
every time i want to get the Value of my DomAttr i get an TypeError:
My Code:
Wanted = page.getByXPath("//span[contains(.,'Some')]/parent::a/#href");
return this
[DomAttr[name=href value=URLSTRING]]
Now i want to geht the value (=URLSTRING) with Wanted.getNodeName();
but every Time i get the Error
Cannot find function getNodeValue in object [DomAttr[name=href value=
same when i use getValue
please help me
There are some things that make no sense in the code (particularly, because it is not complete). However, I think I can guess what the issue is.
getByXPath is actually returning a List (funny thing you missed the part of the code in which you specify it as a list and replaced it with a Wanted).
Note you should probably also have type warnings in the code too.
Now, you can see that the returned value is in square brackets. That means it is a List (confirming first assumption).
Finally, although you happened to miss that part of the code too, I guess you are directly applying the getValue to the list instead of the DomAttr elements in the list.
How to solve it: If you need more than 1 result iterate over the elements of the list (that Wanted word over there). If you need 1 result then user the getFirstByXPath method.
Were my guesses right?
I have Адреса магазинов on page and want to store text, then click on this link and verify that the page where am I going to contains this text in headers. So I tried to find element by xpath, and selenium.getText get the right result, but selenium.click goes to another link. Where have I made a mistake? Thanks in advance!
String m_1 = selenium.getText("xpath=html/body/div[3]/div[2]/div[1]/h4[1]");
selenium.click("xpath=html/body/div[3]/div[2]/div[1]/h4[1]");
selenium.waitForPageToLoad("30000");
assertTrue(selenium.getText("css=h3").contains(m_1));
page:http://www.svyaznoy.ru/map/
Resume:
using xpath=//descendant::a[#href='/address_shops/'][2] or css=div.deff_one_column a[href='/address_shops/'] get right results
using xpath=//a[#href='/address_shops/'] - Element is not currently visible
xpath=//a[#href='/address_shops/'][2] - Element not found
There is a missing slash at the beginning of the expression. I am kind of surprised this got through at all - the first slash means "begin at root node".
Also, it is better to select the <a> element instead of the <h>. Sometimes it works, sometimes is misclicks, sometimes the click doesn't do anything at all. Try to be as concrete as you can be.
Try this one.
String m1 = selenium.getText("xpath=/html/body/div[3]/div[2]/div/h4/a");
selenium.click("xpath=/html/body/div[3]/div[2]/div/h4/a");
selenium.waitForPageToLoad("30000");
// your variable is named m1, but m_1 was used here
assertTrue(selenium.getText("css=h3").contains(m1));
By the way, there are even better XPath expressions you could use. See the documentation, it really is helpful. Just an example, this would work, too, and is much easier to write and read:
String m1 = selenium.getText("xpath=//a[#href='/address_shops/']");
selenium.click("xpath=//a[#href='/address_shops/']");
Sorry, didn't notice page link. Css for second link can be something like that css=div.deff_one_column a[href='/address_shops/']
