how to add a child to a child in XML

how to add a child to a child in XML
Hi, XML doesn't use the `$` to access child nodes. Instead use either `[name]` to get a list of children of that name or `[[name]]` to get the just the first child of that name encountered in the genealogy. Thus for your example... > root$child1 NULL > root[['child1']] <child1 name1="A" name2="B" name3="C"/> On the other hand, you might

how to add a child to a child in XML
Hi, It's a reasonable question. The answer is that it actually is included, but there are many instances across packages where multiple functions are documented on a single help page. The following brings up such a page... (for XML_3.98-1.9) > library(XML) > ?newXMLNode You can see the same on line... https://www.rdocumentation.org/packages/XML/versions/3.98-1.9/topics/newXMLDoc

how to add a child to a child in XML
Just to clarify and hopefully catch the attention of the maintainer: The newXMLNode function is not mentioned in: https://cran.r-project.org/web/packages/XML/XML.pdf which supposedly describes all functions in the package.

Cant test 404 pages in webrick
I tried running webrick in production mode with -e production option. I changed development database name so as to make sure webrick was running in production mode. Now I wanted to test my new 404.html page so I typed an invalid URL, I still get some routing error instead of my 404.html page. Why is this happening with webrick in production. I haven''t even changed any of the environment

Modify objects in function
Dear R community, I do know, that an R function is constructing a copy of any object passed as argument into a function. I program on a larger S4 project for a package, and I arrived at a point where I have to think a little harder on implementation style (especially to spare users complex object handling). I have a function foo(), taking as input arguments two S4 objects of different class

[LLVMdev] [RFC] Storing default function attributes on the module
Hi Duncan, Been thinking about this a bit and a few comments/questions.

before_create is after_validatation :on => :create , when it should be before_validation :on => :create
In ActiveRecord''s callbacks, methods within a before_create callback are called after the validation, but before the model is created. This was an intentional design decision, but I think it was the wrong one. What do you think? When I think of before_create, I think of before_validation :foo, :on => :create, but, by default, before_create is synonymous with after_validation :foo,
