Hi!
I've an XML file whose contents are as following:



<?xml version="1.0" ?>

<response action="registration">

	<element>

    	<properties name="username">cst11</properties>

    	<properties name="playerhandle">238768881697142018728993387950411141</properties>

    	<properties name="skinId">RCA001</properties>

    	<properties name="errcode" >loginnotAllowed</errcode>

	</element>

</response>

I've to get the values ("cst11","238768881697142018728993387950411141","RCA001" and "loginnotAllowed") using TinyXML. How to do this? Can any body post some sample code for this?

I wrote the following code:

 std::string temp = objGen.WStringToString(res).c_str();



	OutputDebugString(objGen.StringToWString(temp).c_str());



	TiXmlDocument doc;

	doc.Parse(temp.c_str() , 0, TIXML_ENCODING_UTF8);	

	doc.SaveFile("response.xml");

	string errorcode;

	if(doc.LoadFile())

	{

		TiXmlElement *res =  doc.FirstChildElement("response");



		if(res)

		{

       	TiXmlElement * ele = res->FirstChildElement("element");

		   if(ele)

		   {

			  TiXmlElement *prop = ele->NextSiblingElement()->NextSiblingElement()->NextSiblingElement()->NextSiblingElement();

			  errorcode = prop->GetText();

		   }

		}

	}

But not returning the inner XML values(cst11,238768881697142018728993387950411141,RCA001and loginnotAllowed). What to do?

TiXmlNode* parent = ...;



TiXmlNode* child = parent->FirstChild();   // parent == properties

if(child && child->Type() == TiXmlNode::TEXT) {

const char* text = child->Value();	// text is the string version of what you want, convert it if need be

}

Can you please clearly write how to get parent value? Sorry. I haven't done XML Parsing before.

Two obvious things. element doesn't have any sibblings and the xml is malformed by closing a properties-tag with /errcode

doc has a RootElement() call, which will be response, response->FirstChildElement("element"), element can then be looped.



TiXmlElement* props = element->FirstChildElement("properties");

while(props)

{

   // props would be parent in my previous post



props = props->NextSiblingElement();  // ok as long as elements children are all <properties>

}

and your xml has some errors which were pointed out.

This code crashes at the following line at tinyxml.cpp:



for ( node = firstChild; node; node = node->next )

when

TiXmlElement* props = element->FirstChildElement("properties");

is executed. What to do?

Hello!

I haven't used TinyXML before but, I looked at your XML file and:



<?xml version="1.0" ?>

<response action="registration">

        <element>

        <properties name="username">cst11</properties>

        <properties name="playerhandle">238768881697142018728993387950411141</properties>

        <properties name="skinId">RCA001</properties>

        <properties name="errcode" >loginnotAllowed</errcode> // Shouldn't this line terminate with the closing tag </properties> instead of </errcode> ? 

        </element>

</response>

It's just a guess though.

It's just a guess though.

I've the correct one in my test environment. It's a mistake while posting. What else to do to get the inner Text?
