下面是在網上找的一段測試linxml2庫是否裝上的程式碼。

#include <stdio.h> 
#include <libxml/parser.h>
#include <libxml/tree.h>
int main(int argc, char **argv)
{
  xmlDocPtr doc = NULL;
  xmlNodePtr root_node = NULL, node = NULL, node1 = NULL;
  doc = xmlNewDoc(BAD_CAST "1.0");
  root_node = xmlNewNode(NULL, BAD_CAST "root");
  xmlDocSetRootElement(doc, root_node);
  xmlNewChild(root_node, NULL, BAD_CAST "node1",BAD_CAST "content of node1");
  node=xmlNewChild(root_node, NULL, BAD_CAST "node3",BAD_CAST"node has attributes");
  xmlNewProp(node, BAD_CAST "attribute", BAD_CAST "yes");
  node = xmlNewNode(NULL, BAD_CAST "node4");
  node1 = xmlNewText(BAD_CAST"other way to create content");
  xmlAddChild(node, node1);
  xmlAddChild(root_node, node);
  xmlSaveFormatFileEnc(argc > 1 ? argv[1] : "-", doc, "UTF-8", 1);
  xmlFreeDoc(doc);
  xmlCleanupParser();
  xmlMemoryDump();    
  return(0);
}

用下面的命令編譯通過。

g++ xmlCreator.cpp -o xmlCreator -I /usr/include/libxml2/  -L /usr/lib -lxml2

後來我把這段程式碼移到Eclipse下編譯。為工程新增連結庫：右鍵單擊工程-》properities->c/c++ build->setting

1.gcc c linker->libraries->Libraries(-l) 新增”xml2".

2.gcc assembler->general->include path(-I) 新增“/usr/include/libxml2/ “
