Hi!
I’m trying to make a XML file, but the now the problem comes. I can now see that some are using Elements like: <name>John</name> and someone likes to do it this way between quotation marks <name ="John">.
What is the different between this and that way of doing these two coding and what are they called?
Is one way better than the other?

推荐答案

在XML <name =John>中在语法上不正确.应该是这样的

In XML <name ="John"> is not syntactically correct. It should be something like this

<person name="John"></person>

然后person称为element ，而name 称为元素person的attribute .正如问题所述，另一种方法是

Then person is called element and name is called the attribute of the element person. As said in the question the other way of doing this is

<person>
    <name>John</name>
</person>

在这里，name 是元素person的child element .
两者都给出信息.关于何时使用attribute和何时使用child element没有严格的规则.但是，一般而言，当与有关元素有关的信息describes something像形容词有关名词时，都可以使用该属性.另一方面，当相关信息如data时可以使用元素.
另一个区别是，如果将其表示为元素，则可以nest 其他元素，也可以具有attributes.但是，如果将其作为属性给出，则它不能具有子元素和其他属性.
这里给出了解释
http://www.w3schools.com/dtd/dtd_el_vs_attr.asp [ http://msdn.microsoft.com/en-us/library/7f0tkwcx (v = vs.80).aspx [

Here, name is the child element of the element person.
Both, give the information. There are no hard and fast rules regarding when to use as an attribute and when to use as child element. But, as a general the attribute can be used when the information concerned describes something about the element concerned, like an adjective describes about a noun. On the other hand an element can be used when the information concerned is like data.
The other difference is that if it is represented as an element then it can nest other elements and also can have attributes. But, if it is given as an attribute then it cannot have child elements and other attributes.
