How do I target all elements in a document except a particular element name? For example I want to exclude the terminate elements. They can occur throughout the document. <root> <terminate attr="1" /> <other> The brown fox jumps over the fence. <terminate> <b>stuff</b> </terminate> </other> </root> I've tried using the not(..) operator without success likely because I'm using it wrong. And frankly trying to Google 'not' is tough! The following xpath should work /root/*[not(self::terminate)] Also, i think you can do it with this as well /root/*[not(name()='terminate')] If you are using XPath 2

So I am working on something that wasn't well thought out in the build from the backend team. That leaves me with a document full of divs. What I am doing is rolling back from the element I need to click on, get the parent container then find an element within the parent which has class="alert-box warn" , class="alert-box dead" , etc... Essentially, I'm trying to use multiple class selectors on each element. When I try to find just alert-box it doesn't seem to be working right. I'm assuming because it has warn, dead, ``fine, etc... How can I find just alert-box* or equivalent to a wildcard

so i have this matrix data = 1 3 4 3 5 2 5 i need to get new data by subtracting the element like this data2-data1 data3-data2 data4-data3 data5-data4 data6-data5 data7-data4 ... datan-data(n-1) so from that data the output should be im = 2 1 -1 2 -3 3 i still trying to manipulate this code but got an error clc data=[1;3;4;3;5;2;5] cnt=size(data,1) for i=1:cnt; im=(data(i)-(data(i-1))); end im diff does what you want. diff(data) BUT if you want to continue with your approach, I imagine the error you get is related to data(i-1) cannot be defined when i = 1 . Your loop should be 2:cnt . Another

This is a weird problem which I don't understand why it would occur. But, doing the following: Elements Fullcoursespaces = fullCourses.select("span[class=note-red]"); //Get the course times Removes duplicates. So it returns two unique elements, but since the rest of the elements are duplicates of these unique elements, they are removed. When instead, it should fill up the elements list with the duplicates regardless. Is there a reason why this is happening? Edit: As a side note, doing document.querySelectorAll("span[class=note-red]"); on the webpage gives me all the elements regardless if they
