- Compile Tinyxml into a static library under Linux
- An application needs to run on a Linux server. It cannot be guaranteed that each server has the libraries that the application depends on, and it is not practical to be too lazy to install it on every server. Therefore, all the libraries used by the application are compiled into static libraries. Just throw it to the server and run. This is an example of an application calling an xml configuration file that depends on the tinyxml library.

- xml learning (8) xml addition, deletion, modification and query
- In project development, we often add, delete, modify and check a table. We put the data in the brush selection table into the gridview and display it in the form of a list based on the conditions. At the same time, we add various styles to the gridview, such as the generally necessary mouse passing, mouse leaving color change, row selection, etc. color deepening, and assigning values to the list data items. , click the Save button to modify an existing piece of data or add a new piece of data, click the Add button to clear the list data items, and click Delete to delete a piece of data.

- xml learning (7) .net obtains the maximum value of xml node or attribute
- In the previous section, we introduced some XML xpath attributes and functions. Now we will introduce two special uses: 1. Get the maximum value of the same node 2. Get the maximum value of a certain attribute of the same node

- xml learning (6) in c#Xpath example
- In c#, we often search and traverse nodes. This is where we can use XPath syntax. XPath syntax is very simple, but powerful enough. XPath can quickly locate nodes or attributes in Xml. It is also the basic knowledge of using xslt.

- xml learning (5) xml configuration gridview column
- Sometimes we are not sure which columns our gridview should display, or we want to dynamically configure the gridview column display and width. In this case, we can use a database that can store column messages and dynamically bind columns by reading the database. This can be achieved by configuring xml. Of course, you can also read the xml for the first time and then insert the column message into the database. Then next time you will determine whether the database has stored the column data. If it has not been stored, then read the xml.

- xml learning (4) Create xml file
- The basic principle of binocular ranging is shown in the figure above. Binocular ranging mainly uses the direct difference (i.e. parallax) between the lateral coordinates of the target point imaged on the left and right views and the distance Z between the target point and the imaging plane. There is an inverse proportional relationship: Z=fT/d. "@scyscyao: In OpenCV, the dimension of f is a pixel point, and the dimension of T is determined by the actual size of the calibration board checkerboard and the user input value, usually in millimeters (of course it can also be set to in order to improve accuracy) 0.1 millimeters), the dimension of d=xl-xr is also a pixel point. Therefore, the dimension of Z is the same as that of T. "Assume that the coordinates of the target point in the left view are (x, y), in The parallax formed on the left and right views is d.

- xml learning (3) html display xml
- Sometimes we need to display xml in html. For example, if we modify the xml and click save, we need to display the xml source code on the page to let us know that the xml has been modified. The best way is to put the xml in the pre element, but you will find There is no line break, and it is definitely ugly to display all one line, so I made a function that iterates over xmlDOM to format and display xml.

- xml learning (2) xml document tree structure diagram
- XML documents form a tree structure. XML documents must contain a root element. This element is the parent element of all other elements. The elements in an XML document form a document tree. The tree starts at the root and expands to the very bottom of the tree. All elements can have child elements:

- Java object, Json, Xml conversion tool Jackson is used
- It is very common to convert an object into a string in Json format in Java projects. There are many toolkits that can achieve this requirement, such as Gson, JSON-lib, Jackson, etc. This article mainly introduces the use of Jackson. In addition to converting Java objects and Json strings, Jackson can also convert Java objects into Xml format. It is relatively simple to use and is said to be relatively efficient.
