Imagining that some info might be not present, like in the following
example, Michael has no age
Example:
<population>
<person>
<name>John</name>
<age>54</age>
</person>
<person>
<name>Michael</name>
</person>
</population>
I want to write the previous XML to a continuous string:
char* xml =
"<population><person><name>John</name><age>54</age></person><person><name>Michael</name></person></population>"
since i'm reading the XML file from the top i get:
field name: population ; field value:
field name: person ; field value:
field name: name ; field value: John
field name: age ; field value: 54
field name: person ; field value:
field name: name ; field value: Michael
What i need to know is that after the age from John, i need to close the tag
person </person> and open a new one <person>... Since the age might be not
present, the closing tag </person> might come after the </name> tag.
This is why i'm asking if there is a way to know if the tag i'm reading now
is in a different depth in the tree compared to the previous tag.
If this is not possible, you are welcome to suggest other approaches :-)
Thank you
