HtmlUnit converts dom attribute type="Value" to type="value" (converts the value to lower case)

Hi, I wanted to make you aware of this bug in HtmlUnit 2.6. The following html DOM element: <input name="Test1" type="Text" value="Test1" /> will appear in HtmlUnit as <input name="Test1" type="text" value="Test1" /> Notice that "Text" got changed to "text". As far as I know, this is happening only with the type="..." attributes. Because of this issue, my XPath search is not finding this DOM element. Below is a short java app. that reproduces the bug. I appreciate your contribution and thank you for the great free product! -Ivaylo package yada; import com.gargoylesoftware.htmlunit.BrowserVersion; import com.gargoylesoftware.htmlunit.WebClient; import com.gargoylesoftware.htmlunit.html.HtmlElement; import com.gargoylesoftware.htmlunit.html.HtmlPage; /** * This is a use case showing that HtmlUnit 2.6 converts * the value of node attribute "type" to lower case. * To run the test, save the simple html code below * into a file C:/Temp/test.html and run this main() method. <html> <head><title>Test</title></head> <body> <form name="test" action="."> <input name="Test1" type="Text" value="Test1" /> </form> </body> </html> * */ public class TestDomElemAttrCaseSensitivity { public static void main(String[] arghhhh) throws Exception { WebClient client = new WebClient(BrowserVersion.FIREFOX_3); HtmlPage page = client.getPage("file:///C:/Temp/test.html"); System.out.println(page.asXml()); { // XPATH search for //input[@type='Text'] returns null. final HtmlElement textInputElement = (HtmlElement) page.getFirstByXPath("//input[@type='Text']"); System.out.println(textInputElement); // prints null } { // XPATH search for //input[@type='text'] returns HtmlTextInput[<input name="Test1" type="text" value="Test1">]. final HtmlElement textInputElement = (HtmlElement) page.getFirstByXPath("//input[@type='text']"); System.out.println(textInputElement); // prints HtmlTextInput[<input name="Test1" type="text" value="Test1">] } } } ------------------------------------------------------------------------------ Come build with us!

Hi,
I don't think that this is a bug. If you try to evaluate such an XPath in Firefox, you won't find any result either: HtmlUnit just normalize the value of the value attribute as done in Firefox.

Hi,
I guess you've been testing with Firefox 3.5, whereas I was testing with Firefox 3.1. Following code gives different results in these browsers: <html><body> <input type="Text"> <script> var nb = document.evaluate("count(//input[@type = 'text'])", document, null, XPathResult.ANY_TYPE, null).numberValue; alert("with 'text': " + nb); nb = document.evaluate("count(//input[@type = 'Text'])", document, null, XPathResult.ANY_TYPE, null).numberValue; alert("with 'Text': " + nb); </script> </body></html> This being said, I think that: - JavaScript interpretation should behave like in browsers, meaning that HtmlUnit should respect case of type attribute as browser do. Please open an issue for that if it is important for you. - HtmlUnit's API should allow not to bother whether some of the attributes have been written with lower case and other with upper case: it would just make code less readable particularly as XPath 1 has no function to convert case.
