Hi There,
I'm parsing a XmlDocument that has a inline Schema.
In order to get the types of the variables that exist in "data
sector" I go trough the schema checking the names of the variables and then
using xPath I will the value of that variable.
I'm getting problems if I try to make two "queries" using xPath (in
the example I use the same query):
code snippet
xmlXPathObjectPtr xDataResult;
xmlNodePtr dataNode;
xmlXPathObjectPtr xDataResult1;
xmlNodePtr dataNode1;
char* value;
//Query 1
xDataResult =
xmlXPathEvalExpression(*xPathData,context);
dataNode = xDataResult->nodesetval->nodeTab[0];
value = xmlNodeListGetString(doc,
dataNode->xmlChildrenNode, 1);
printf(">>>>>>> '%s' name:%s value:%s type:%s
(simpleField) <<<<<<<\n",*xPathDoc, dataNode->name,
value,xmlGetProp(node,"type"));
xmlFreeNode(dataNode);
xmlXPathFreeObject(xDataResult);
//Query 2
xDataResult1 =
xmlXPathEvalExpression(*xPathData,context);
dataNode1 = xDataResult->nodesetval->nodeTab[0];
value = xmlNodeListGetString(doc,
dataNode->xmlChildrenNode, 1);
printf(">>>>>>> '%s' name:%s value:%s type:%s
(simpleField) <<<<<<<\n",*xPathDoc, dataNode->name,
value,xmlGetProp(node,"type"));
xmlFreeNode(dataNode);
xmlXPathFreeObject(xDataResult);
do I need to do something between the 2 queries ? If I recreate the
doc and the context this will work, but there must be a better way.
Thank you in advance,
Luís Pinho
