Dom4j (XPath) parsing XML example

Import java. Io. file;
Import java. util. List;
Import org. dom4j. Document;
Import org. dom4j. extends entexception;
Import org. dom4j. element;
Import org. dom4j. Io. saxreader;

Public class main {
Public static void main (string [] ARGs ){
Saxreader = NULL;
Document Doc = NULL;
Try {
Saxreader = new saxreader ();
Doc = saxreader. Read (new file ("D:/SS. xml "));
List <element> List = Doc. selectnodes ("// result // value ");
System. out. println (list + "list ");
For (Element EntryItem: list ){
System. out. println (EntryItem. getName ());
String table = EntryItem. elementTextTrim ("table ");
String SQL = EntryItem. elementTextTrim ("SQL ");
System. out. println ("table =" + EntryItem. elementTextTrim ("table "));
System. out. println ("SQL =" + EntryItem. elementTextTrim ("SQL "));

}
} Catch (exception e ){
E. printstacktrace ();
}
}
}

The running result is:

[Org. dom4j. tree. defaultelement @ 18f6235 [element: <value attributes: [Org. dom4j. tree. defaultattribute @ 1dfc547 [attribute: name value "value"]/>] list
Value
Table = tbl_notice
SQL = select title, content from tbl_notice order by ID DESC
 

 

The content of the SS. xml file is:

<? XML version = "1.0" encoding = "UTF-8"?>

<Result>
<Value name = "value">
<Table> tbl_notice </table>
<SQL> select title, content from tbl_notice order by id desc </SQL>
<Style> </style>
</Value>
</Result>
