Ok,Its working with following way.I used SPObject *obj = doc->getRoot(); insted of doc->getRoot()->firstChild(); But it give outPut Four line ,The first line repeat 2 times. http://old.nabble.com/file/p32080719/Data.txt Data.txt why its happen ,is there any error in code ?
void write_coordinates(SPObject *obj,FILE *fp) { if(!SP_IS_ITEM(obj)) return ;
Inkscape::XML::Node *newitem= obj->getRepr(); Inkscape::XML::Node *path = sp_repr_lookup_name(newitem, "svg:path", -1);
if ( path != NULL ) { gchar const *svgd = path->attribute("d"); fprintf(fp,"PATH2: %s \n ", svgd ); } }
void visit_all_objects(SPObject *obj,FILE *fp) { if (obj == NULL) return;
write_coordinates(obj, fp); // write object's coordinates to a file here SPObject *child = obj->children; for (; child; child = child->next) { visit_all_objects(child,fp); } } bool sp_file_save_as(Gtk::Window &parentWindow, gpointer /*object*/, gpointer /*data*/) { if (!SP_ACTIVE_DOCUMENT) return false;
SPDocument *doc = inkscape_active_document(); SPObject *obj = doc->getRoot();//->firstChild();
FILE *fp = fopen("D:\Data.txt","w"); visit_all_objects(obj, fp); fclose(fp);
return true; }

I try to implement your code in another following way .
The Input file name :drawing-1.svg http://old.nabble.com/file/p32072659/drawing-1.svg drawing-1.svg
with above code I can get only One line coordinate instead of the two line.Please check the attached output file The OutPut file name :Data1.txt http://old.nabble.com/file/p32072659/Data1.txt Data1.txt
Now how can i get next line coordinate ?
This cannot be done this way. You must define a recursive function (a function that calls itself) like I told you earlier. Please tell me what was wrong with the code I posted. If it gave an error, please post the error.
I guess the previous code could have crashed, so here is another attempt:
void write_coordinates(SPObject *obj) { Inkscape::XML::Node *path = obj->getRepr(); gchar const *svgd = path->attribute("d"); if (svgd) fprintf(fp,"PATH2: %s \n ", svgd ); }
void visit_all_objects(SPObject *obj, FILE *fp) { if (obj == NULL) return;
write_coordinates(obj, fp); // write object's coordinates to a file here SPObject *child = obj->children; for (; child; child = child->next) { visit_all_objects(child); } }
bool sp_file_save_as(Gtk::Window &parentWindow, gpointer /*object*/, gpointer /*data*/) { if (!SP_ACTIVE_DOCUMENT) return false;
SPDocument *doc = inkscape_active_document(); SPObject *obj = doc->getRoot()->firstChild();
FILE *fp = fopen("D:\Data.txt","a"); visit_all_objects(obj, fp); fclose(fp);
return true; }
