阅读更多关于 Parsing XML in R: Incorrect namespaces

XML files are like this: xml_nons.xml <?xml version="1.0" encoding="UTF-8"?> <XML> <Node> <Name>Name 1</Name> <Title>Title 1</Title> <Date>2015</Date> </Node> </XML> And the other: xml_ns.xml <?xml version="1.0" encoding=

Does HTML5 support namespaces?

问题 Are we allowed to extend HTML5 with new tags like <foo:bar> in HTML5? I ask because the Facebook API includes just this kind of thing ** , and our pages are defined as HTML5. More specifically, is it possible to make a HTML5-conformant page that uses fb:fbml? 回答1: Strictly speaking, no. You can have JavaScript code write the FBML which gets around any potential validation issues, but it's bad form. That aside, even if you could, you don't want to make a page that uses FBML. FBML will be

How to ingore namespace prefixes on VTD Xpath lookup

阅读更多关于 How to ingore namespace prefixes on VTD Xpath lookup

I'm building a VTD based XML Parsing engine in order to process files from several input systems. I'm currently trying to get values from tags with namespace prefix: <?xml version="1.0" encoding="UTF-8"?> <cli:clients xmlns declarations > <cli:client> <dat:name>CLIENT NAME</dat:name> <dat:age>1</dat:age> </cli:client> and querying the following Xpaths: //client/age/text() //client/name/text() How can I set VTD AutoPilot to ignore the namespace prefix? NOTE : I cannot change the xpaths as I already have this engine in production implemented with JDK's default xpath engine. UPDATE : See below

Intellisense not working when trying to define an xmlns in VS2012

阅读更多关于 Intellisense not working when trying to define an xmlns in VS2012

In visual studio 2012 I start typing it out and I'm immediately getting xaml errors as I'm typing and no suggestions. The problem is, I don't know what the exact ones I need to add, so I'm a little dependent on the intellisense. Regular intellisense works just fine. Why is this? The problem seems to have been the fact that I was using .NET 4.0 Client

问题 When you have xml nodes with namespaces like: <ns:abc> then getElementsByTagName("abc"); fails, but getElementsByTagName("ns:abc"); works. But the issue is I don't know what is the namespace prefix chosen. Also for me, getElementsByTagNameNS("*", "abc"); and getElementsByTagNameNS("http://abcnamespace.com", "abc"); both return null. If device is of interest, I am using CM7 on Nook. I don't want to use SAX, any other clean way to read the node lists. 回答1: DocumentBuilderFactory
