Use of libxml2 in Fedora

1. Download and install libxml2. Download the source code package of your own version from the official website. Http://rpmfind.net/linux/rpm2html/search.php? Query = libxml2-devel I download the version for the libxml2-devel-2.6.32-11.10.i586 decompress, compile and run./configure & ndash; prefix/usr/local/xml # Install

1. Download and install

Download libxml2, the official website, and download the source code package of the appropriate version.

Http://rpmfind.net/linux/rpm2html/search.php? Query = libxml2-devel

I downloaded the version for libxml2-devel-2.6.32-11.10.i586

Decompress, compile, and run

./Configure-prefix/usr/local/xml # installation directory

Make

Make install

After the installation is complete, four more folders are generated under/usr/local/xml.

Bin include lib share

Ii. Run demo

Use Eclipse to create a C ++ project.

1. Solve the header file path problem.

The libxml header file is automatically added to the default directory. If Eclipse is not automatically added, You can manually add it, right-click properties, and make the following changes.

The header file path after installation is

$/Include/libxml2/libxml/*. h

The working directory in the source code is

At this time, the project cannot find these files. What we need to do is to modify the directory.

$/Include/libxml/*. h

Of course, there is also a way to modify the code contained in those header files. For example:

#include < libxml/xmlversion.h >

Change

#include < libxml2/libxml/xmlversion.h >

This method is not so silly to process dozens of headers.

2. demo src

Void writeXML (void) {// definition document and node pointer xmlDocPtr doc = xmlNewDoc (BAD_CAST "1.0"); xmlNodePtr root_node = xmlNewNode (NULL, BAD_CAST "root "); // set the root node xmlDocSetRootElement (doc, root_node); // directly create the node xmlNewTextChild (root_node, NULL, BAD_CAST "newNode1", BAD_CAST "newNode1 content") in the root node "); xmlNewTextChild (root_node, NULL, BAD_CAST "newNode2", BAD_CAST "newNode2 content"); xmlNewTextChild (root_node, NULL, BAD_CAST "NewNode3", BAD_CAST "newNode3 content"); // create a node, set its content and attributes, and add the root node xmlNodePtr node = xmlNewNode (NULL, BAD_CAST "node2 "); xmlNodePtr content = xmlNewText (BAD_CAST "node content"); xmlAddChild (root_node, node); xmlAddChild (node, content); xmlNewProp (node, BAD_CAST "attribute ", BAD_CAST "yes"); // create a son and grandson node = xmlNewNode (NULL, BAD_CAST "son"); xmlAddChild (root_node, node); xmlNodePtr grandson = xmlNe WNode (NULL, BAD_CAST "grandson"); xmlAddChild (node, grandson); xmlAddChild (grandson, xmlNewText (BAD_CAST "This is a grandson node ")); // store the xml document int nRel = 0; nRel = xmlSaveFile ("CreatedXml. xml ", doc); if (nRel! =-1) {cout <"an xml document is created and written" <
 
  
3. Set lib
  
Eclipse sets the link path:/usr/local/xml/lib
  
Set the Connection Library xml2
  
Add the following parameters during command Compilation:
  
-L/usr/local/xml/lib/-lxml2
  
Well, the compilation and execution below will be OK.
