(The documentation of function count_XMLemptyElements)

Last Update: 2022/11/30

◆機能・用途(Purpose)

XML空要素の個数をカウントする。
Count the number of XML empty-elements.

◆形式(Format)

#include <xml/info.h>
inline int count_XMLemptyElements
(const int Nelements,const _Bool ∗emptyElementFlag)

◆引数(Arguments)

Nelements	XML要素数。関数count_XMLelements_in_textの戻り値を渡す。 The number of XML elements. Use the return value of function count_XMLelements_in_text.
emptyElementFlag	各XML要素が空要素か否かを示す真偽値(空要素の場合にtrue) を並べた配列。関数identify_XMLemptyElementsの戻り値を渡す。 An array composed of logical values that indicate whether individual XML elements are empty-elements (true for empty-elements). Use the return value of function identify_XMLemptyElements.

◆戻り値(Return value)

XML空要素の個数。
The number of XML empty-elements.

◆使用例(Example)

const char XMLdata[]="<dataset><data1><subdata1a></s ubdata1a><subdata1b></subdata1b><empty1c/></data1><data2>< subdata2a></subdata2a><subdata2b></subdata2b><subdata2c></subdata2c></data2></dataset>"

int Nelements=count_XMLelements_in_text(strlen(XMLdata),XMLdata);

int ∗startTags_st =list_XMLstartTag_startPos(strlen(XMLdata),XMLdata,Nelements);

int ∗startTags_en =list_XMLstartTag_endPos(strlen(XMLdata),XMLdata,Nelements,startTags_st);

_Bool ∗emptyElementFlag=identify_XMLemptyElements (strlen(XMLdata),XMLdata,Nelements,startTags_st,startTags_en);

int NemptyElements=count_XMLemptyElements(Nelements,emptyElementFlag);
