Introduction to XML read-write library xmlcpp in asp.net (d): Traversal search

Xmlcpp support Convenient traversal search, the algorithm is efficient and robust. Can traverse search node name, node attribute key, node attribute value, and node literal text. Except that the key search needs to match exactly, the rest of the search only needs to provide a contiguous field of the content being searched.

Method List:

1. Find_has_name
2. Find_has_key
3. Find_has_value
4. Find_has_text

Here's a simple example.

First, you generate an XML file that reads as follows:

The code is as follows

Copy Code

<bookstore> <book isbn= "7-111-19149-2" type= "compulsory course" > <title> Data Structure </title> <author> Min </author> <price>30</price> </book> <book isbn= "7-111-19149-3" type= "compulsory course" > <title> router and Exchange-based Internet </title> <author> Cheng Qinghui </author> <price>27</price> </book> <book isbn= "7-111-19149-4" type= "compulsory course" > <title> Computer hardware Technology base </title> <author> Li Jizan </author> <price>25</price> </book> <book isbn= "7-111-19149-5" type= "compulsory course" > <title> Software Quality assurance and management </title> <author> Zhu Shaomin </author> <price>39</price> </book> <book isbn= "7-111-19149-6" type= "compulsory course" > <title> algorithm design and Analysis </title> <author> Wang </author> <price>23</price> </book> <book isbn= "7-111-19149-1" type= "compulsory course" > <title> Computer operating System </title> <author>7-111-19149-1</author> <price>28</price> </book> </bookstore>

The demo code is as follows:
