The basic point (as pointed out by Kev, above), is that the namespace URI is the important part of the namespace, rather than the namespace prefix, the prefix is an “arbitrary convenience” As for why you need a namespace manager, rather than there being some magic that works it out using the document, I can … Read more
Maybe *[local-name() = ‘A’ and not(descendant::*[local-name() = ‘B’])]? Also, there should be only one root element, so for /A[…] you’re either getting all your XML back or none. Maybe //A[not(B)] or /*/A[not(B)]? I don’t really understand why /A[not(B)] doesn’t work for you. ~/xml% xmllint ab.xml <?xml version=”1.0″?> <root> <A id=”1″> <B/> </A> <A id=”2″> </A> … Read more
Generally I would consider the use of an unprefixed // as a bad smell in an XPath. Try this:- /DocText/WithQuads/Page/Word[text()=’July’ and Quad/P1/@X > 90] Your problem is that you use the //P1[@X < 90] which starts back at the beginning of the document and starts hunting any P1 hence it will always be true. Similarly … Read more
I refactored this from another example. It will attempt to check or there is for sure a unique id and if so use that case to shorten the expression. function createXPathFromElement(elm) { var allNodes = document.getElementsByTagName(‘*’); for (var segs = []; elm && elm.nodeType == 1; elm = elm.parentNode) { if (elm.hasAttribute(‘id’)) { var uniqueIdCount … Read more
Do you want to find elements that contain “match”, or that equal “match”? This will find elements that have text nodes that equal ‘match’ (matches none of the elements because of leading and trailing whitespace in random2): //*[text()=’match’] This will find all elements that have text nodes that equal “match”, after removing leading and trailing … Read more
XPath 1.0 doesn’t handle regex natively, you could try something like //*[starts-with(@id, ‘sometext’) and ends-with(@id, ‘_text’)] (as pointed out by paul t, //*[boolean(number(substring-before(substring-after(@id, “sometext”), “_text”)))] could be used to perform the same check your original regex does, if you need to check for middle digits as well) In XPath 2.0, try //*[matches(@id, ‘sometext\d+_text’)]
You can find a parent element by using .. xpath: input_el = driver.find_element_by_name(‘A’) td_p_input = input_el.find_element_by_xpath(‘..’) What about making a separate xpath for getting selected option, like this: selected_option = driver.find_element_by_xpath(‘//option[@selected=”selected”]’)
To use XPath with LINQ to XML add a using declaration for System.Xml.XPath, this will bring the extension methods of System.Xml.XPath.Extensions into scope. In your example: var value = (string)xml.XPathEvaluate(“/response/data/hash”);
I notice that the only “online” checker in the answers seems a bit clunky. It requires submission to a server, and it doesn’t handle namespaces properly. I thought I could do better, and that such a tool would be quite useful, so I made one. I realize it is slightly self-promoting to mention it here, … Read more
