This is a bit abstract, not easy to understand, and I have learned a little bit, but it is very remarkable. It brings us a lot of convenience in XML applications, the XML function has also been greatly improved, and I feel like it. Oh, there is something wrong with it. Don't laugh!
Before entering the subject, we will reference an example:
<Table>
<Tr>
<Td> Apples </td>
<Td> Bananas </td>
</Tr>
</Table>
In the above XML, it is a bit similar to the table function in HTML we have seen before. In fact, you can also think it is as simple as that;
<Table>
<Name> African Coffee Table </name>
<Width> 80 </width>
<Long> 120 </length>
</Table>
In this XML, we describe the information of a table. In this way, if we put the two XML into an XML file, we will encounter a naming conflict, so there is Name space.
XML namespace-the solution to the above problems:
I. Use a prefix to solve naming conflicts:
The above two files are changed to the following:
1 -- <H: tr>
<H: td> Apples <H: td> Bananas </H: tr>
</H: table> 2 -- <f: table>
<F: name> African Coffee Table </f: name>
<F: width> 80 </f: width>
<F: length> 120 </f: length>
</F: table> can two different types of information be clearly separated by <H: tr>
<H: td> Apples <H: td> Bananas </H: tr>
</H: table> 2 --- <f: table xmlns: f = "http://www.w3.org/TR/xsl">
