What is the selection mode?
The select mode statement extracts data from XML, which is a simple method to obtain data. all the tags have a select attribute and select the specific named data in XML.
Note that every xsl file needs to be imported into the xsl namespace, http://www.w3.org/tr/wd-example, for example, after the xmlheader is declared:
1,
This statement selects a condition one by one (select) and uses the condition. For example, there is a list of users in the following database:
5do8
1
. NET, PHP Design
Cjjer
2
DataBase Manage
You only need to output all Name columns. here there are two headers:
1: You need to select the data under each User node, that is, you need to locate the User node, we apply
For-eachThe following
Select.
2: Select the Name node. we apply it.
Value-The following
Select.
Create an xsl file:
Keep as UserList_for-each.xsl. add in the second line of the xml file:
In IE 5 or later browsers, the consequences are visible.
For-each also supports sorting. The order-by statement is separated by semicolons (;) and serves as a list of sorting scales. Add the plus sign () before the list element to sort the content of this tag in ascending order, and add the minus sign (-) to reverse order. As a simplified representation, the sorting scale list is the sequence of sub-tags specified by the select statement. each tag is separated.
2,
Value-of is the value of the current node.
For example Select the value of the Name node.
Xsl: sortSorting
For nodes that match with xsl: for-each or xsl: apply-templates, you can use xsl: sort to sort the content of the selected nodes.
Sort by case
Key words with id are prioritized by uppercase
Key words with id are prioritized by lower case
Sort by letter
Sort key words by letter in ascending order
Sort key words by letter in descending order
Sort by data type
The key words of id are sorted by text type. for example, for a group of id data of 44,305 and, the sorting result is, and 44.
Sort by data type with id as the key word. the result of sorting the above group of data is 101,305
In addition, there is also a way to specify the sort, that is, the order-by applied in the previous student roster example: You can also sort the output students by names.

Xsl: apply-templates uses the defined Template
For example: ......
The preceding three methods have a common application method, that is, the Select statement must be selected. The Select statement syntax is XPath. The Application Specification of XPath will be described in the next section.
