How to create DOM object from html page received over XMLHttpRequest?

问题 I'm developing a chromium extension so I have cross-host permissions for XMLHttpRequests for the domains I'm asking permissions for. I have used XMLHttpRequest and got an HTML webpage (txt/html). I want to use XPath (document.evaluate) to extract relevant bits from it. Unfortunatly I'm failing to construct a DOM object from the returned string of the html. var xhr = new XMLHttpRequest(); var name = escape("Sticks N Stones Cap"); xhr.open("GET", "http://items.jellyneo.net/?go=show_items&name="

Parsing XML in a Web Worker

阅读更多关于 Parsing XML in a Web Worker

I have been using a DOMParser object to parse a text string to an XML tree. However it is not available in the context of a Web Worker (and neither is, of course, document.ELEMENT_NODE or the various other constants that would be needed). Is there any other way to do that? Please note that I do not want to manipulate the DOM of the current page. The XML file won't contain HTML elements or anything of the sort. In fact, I do not want to touch the document object at all. I simply want to provide a text string like the following: <car color="blue"><driver/></car> ...and get back a suitable tree

顺便提一下，今天做项目有一点问题，如何让服务程序接口返回的就是json，而不需要使用 jQuery.ajax设置 dataType就能得到json呢？众所周知，服务端的数据以json字符串输出，文档类型是 “ text/html ”，因此返回前台的默认是字符串，如果返回前台的指定为json, 需要设置http响应头 application/json ，这样返回的直接就是json对象了。注意，必须在输出流之前设置响应头 //java jsp servlet中,在struts中有2种输出json的方式，一种是类似serlvet,另一种是进行json配置,在springmvc中可以直接返回json @Override protected void doPost(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException { response.setContentType("application/json;charset=UTF-8"); // request.setCharacterEncoding("UTF-8"); PrintWriter out = request.getWriter(); out.println("{'name':'zhangsan','age

问题 I am trying to create a FF AddOn that brings some XML data from a website. But I can't find a way to parse my RESPONSE. First I used DOMParser but I get this error: ReferenceError: DOMParser is not defined. Someone suggested to use XMLHttpRequest, because the parsing is done automatically but then I get this other error: Error: An exception occurred.

JavaScript DOMParser access innerHTML and other properties

阅读更多关于 JavaScript DOMParser access innerHTML and other properties

I am using the following code to parse a string into DOM: var doc new DOMParser().parseFromString(string, 'text/xml'); Where string is just something like <!DOCTYPE html><html><head></head><body>content</body></html> . typeof doc gives me object . If I do something like doc.querySelector('body') I get a DOM object back. But if I try to access any properties, like you normally can, it gives me undefined : doc.querySelector('body').innerHTML; // undefined The same goes for other properties, e.g. id . The attribute retrieval on the other hand goes fine doc.querySelector('body').getAttribute('id')

问题 This question already has answers here : Cross-Browser Javascript XML Parsing (3 answers) Closed 6 years ago . I need to be able to parse XML using JavaScript. The XML will be in a variable. I would prefer not to use jQuery or other frameworks. I have looked at this, XML > jQuery reading. 回答1: I'm guessing from your last question, asked 20 minutes before this one, that you are trying to parse (read and convert) the XML found through using GeoNames' FindNearestAddress.
