Hi , I read many the times the documents of Libxml2 and some links : http://julp.developpez.com/c/libxml2/?page=sax#L3.2.1 But, I do not manage to find a solution with my problem because it is the first time that I make the handling of file XML in a program C by using method SAX of the library Iibxml2 . Moreover, the remainder of my work is based on the result found in the solution of this problème. I want to use a solution suggested by you like a function to call it in my program. My work consists in making two things (two functions):
- the first function makes it possible to extract information (which is character strings) which exist between the beacon <intent> and < \ intent> concerning the last identifier <ID> < \ ID> of the last beacon <concept> < \ concept> this function gives us like a result a table or a file containing: “d b a c” In our case here, there will be only one line of the file or only one box of the table containing “d b a c” - The second function makes it possible to extract information (character strings) which exists between the beacon <intent> and < \ intent> of all the identifiers <ID> < \ ID> except the last identifier <ID> < \ ID> and if the beacon <intent> < \ intent> of the first identifier <ID> < \ ID> is not empty then we put information between <intent> < \ intent> in the result If not if the beacon <intent> < \ intent> of the first identifier <ID> < \ ID> is empty as in our case then we do not put information between <intent> < \ intent> in the result. this function gives us like a result a table or a file containing the required character strings. In our case here, there will be lines of the file or many boxes of the table containing: "a" "b" "c" "d" "a c" "b c" "b d" "c d" "a b d" Here my file XML complete named “essai.lat.xml”: Code: XML <Galicia_Document> <Lattice numberObj= " 5 " numberAtt= " 4 " numberCpt= " 11 " > <Name>lattice (test) </Name> <Object>3</Object> <Object>2</Object> <Object>1</Object> <Object>5</Object> <Object>4</Object> <Attribute>d</Attribute> <Attribute>b</Attribute> <Attribute>c</Attribute> <Attribute>a</Attribute> <Concept> <ID> 1 </ID> <Extent> <Object_Ref>3</Object_Ref> <Object_Ref>2</Object_Ref> <Object_Ref>1</Object_Ref> <Object_Ref>5</Object_Ref> <Object_Ref>4</Object_Ref> </Extent> <Intent> </Intent> <UpperCovers> </UpperCovers> </Concept> <Concept> <ID> 2 </ID> <Extent> <Object_Ref>1</Object_Ref> <Object_Ref>5</Object_Ref> </Extent> <Intent> <Attribute_Ref>a</Attribute_Ref> </Intent> <UpperCovers> <Concept_Ref>1</Concept_Ref> </UpperCovers> </Concept> <Concept> <ID> 5 </ID> <Extent> <Object_Ref>2</Object_Ref> <Object_Ref>5</Object_Ref> <Object_Ref>4</Object_Ref> </Extent> <Intent> <Attribute_Ref>b</Attribute_Ref> </Intent> <UpperCovers> <Concept_Ref>1</Concept_Ref> </UpperCovers> </Concept> <Concept> <ID> 4 </ID> <Extent> <Object_Ref>3</Object_Ref> <Object_Ref>1</Object_Ref> <Object_Ref>4</Object_Ref> </Extent> <Intent> <Attribute_Ref>c</Attribute_Ref> </Intent> <UpperCovers> <Concept_Ref>1</Concept_Ref> </UpperCovers> </Concept> <Concept> <ID> 3 </ID> <Extent> <Object_Ref>3</Object_Ref> <Object_Ref>2</Object_Ref> <Object_Ref>5</Object_Ref> </Extent> <Intent> <Attribute_Ref>d</Attribute_Ref> </Intent> <UpperCovers> <Concept_Ref>1</Concept_Ref> </UpperCovers> </Concept> <Concept> <ID> 8 </ID> <Extent> <Object_Ref>1</Object_Ref> </Extent> <Intent> <Attribute_Ref>c</Attribute_Ref> <Attribute_Ref>a</Attribute_Ref> </Intent> <UpperCovers> <Concept_Ref>2</Concept_Ref> <Concept_Ref>4</Concept_Ref> </UpperCovers> </Concept> <Concept> <ID> 9 </ID> <Extent> <Object_Ref>4</Object_Ref> </Extent> <Intent> <Attribute_Ref>b</Attribute_Ref> <Attribute_Ref>c</Attribute_Ref> </Intent> <UpperCovers> <Concept_Ref>5</Concept_Ref> <Concept_Ref>4</Concept_Ref> </UpperCovers> </Concept> <Concept> <ID> 6 </ID> <Extent> <Object_Ref>2</Object_Ref> <Object_Ref>5</Object_Ref> </Extent> <Intent> <Attribute_Ref>d</Attribute_Ref> <Attribute_Ref>b</Attribute_Ref> </Intent> <UpperCovers> <Concept_Ref>5</Concept_Ref> <Concept_Ref>3</Concept_Ref> </UpperCovers> </Concept> <Concept> <ID> 7 </ID> <Extent> <Object_Ref>3</Object_Ref> </Extent> <Intent> <Attribute_Ref>d</Attribute_Ref> <Attribute_Ref>c</Attribute_Ref> </Intent> <UpperCovers> <Concept_Ref>4</Concept_Ref> <Concept_Ref>3</Concept_Ref> </UpperCovers> </Concept> <Concept> <ID> 11 </ID> <Extent> <Object_Ref>5</Object_Ref> </Extent> <Intent> <Attribute_Ref>d</Attribute_Ref> <Attribute_Ref>b</Attribute_Ref> <Attribute_Ref>a</Attribute_Ref> </Intent> <UpperCovers> <Concept_Ref>2</Concept_Ref> <Concept_Ref>6</Concept_Ref> </UpperCovers> </Concept> <Concept> <ID> 10 </ID> <Extent> </Extent> <Intent> <Attribute_Ref>d</Attribute_Ref> <Attribute_Ref>b</Attribute_Ref> <Attribute_Ref>c</Attribute_Ref> <Attribute_Ref>a</Attribute_Ref> </Intent> <UpperCovers> <Concept_Ref>10</Concept_Ref> <Concept_Ref>8</Concept_Ref> <Concept_Ref>9</Concept_Ref> <Concept_Ref>7</Concept_Ref> </UpperCovers> </Concept> </Lattice> </Galicia_Document> I would be very grateful if you help me because I enormously need the solution to my problem. Good work and good day.
