Using tinyXml2, I can parse 

<MSG_TIME>2010-07-01 14:28:20</MSG_TIME>
just fine, but 
<MSG_TIME></MSG_TIME>
and 
<MSG_TIME/>
both throw exceptions in C++ when those are perfectly valid XML (to my knowledge). Does anyone have a fix or suggestion for this? I do not control the source of this XML, and I need to be error tolerant.

  • Does the xsd you're using prevent empty elements -- http://stackoverflow.com/questions/4126646/prevent-empty-elements-in-xml-via-xsd? – hd1 Dec 31 '12 at 21:42
  • Report the bug to the authors of the library (and, if you can, fix it yourself). Meanwhile I would go for a better XML parsing library, like pugixml (my favorite). – Yakov Galka Dec 31 '12 at 21:47

This answer assumes you're trying to load valid XML with an empty element.

XMLElement::GetText() returns nullptr if the element is empty, so you can do a simple check like this:

std::string szData;

// Get the element
XMLElement pElement = xmlDoc.FirstChildElement("MyElement");

// Check whether the element contains data & if so, extract it as text
if (pElement->GetText() != nullptr) szData = poElement->GetText();

This question actually pointed out a bug with the TinyXML2 tutorial I wrote a few months ago, so thanks for posting it! :)
