Split file by XML tag

由 若如初见. 提交于 2019-12-07 15:14:24
I have a very large xml file (1.25 GB) that I need to split into smaller files to be able to process them. The file contains linguistic data that is headed and footed by the tags: < text id="www.example.com> and < /text> I would like to split the larger file by these tags. So that, for example, < text id="www.example.com> Hello < /text> < text id="www.example.com> This is < /text> < text id="www.example.com> An Example < /text> Would essentially be three different files: with the beginning and end marked by the "text" tags. For example: File 1 < text id="www.example.com> Hello < /text> File 2

How can I add this command to the Image in the code behind? Here is the code that creates my image: var image = new Image { ClassId = item.Path, Aspect = Aspect.AspectFill, Source = item.ThumbNailImage, Rotation = 90, Margin = 10, GestureRecognizers = { _tgr }, //Command here, but how? }; This documentation on Microsoft's website is very helpful in explaining how to set attached properties in

问题 I've been seeing tutorials where people are creating the methods like CanExecute in their code. I'm assuming they are doing this to help the reader understand how it all works. When I look up Command and ICommand it takes me to the ICommand class on MSDN that is used for Windows Store apps. Is there not a Command class for WPF? 回答1: The built-in implementation of ICommand in WPF is RoutedCommand (and its sibling RoutedUICommand ). RoutedCommand works like this: The Execute and CanExecute

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . Being a super user , I executed the following command on linux rm rm which removes itself. Because when process is in execution , its reference count is not zero.Hence it cannot be deleted. So I am bemused, how and why does it happen? I tried the same with chown 0000 chown as well. cp -r Dir1/ Dir2/ In above
