Gumbo Parser - Get innerText of an element

Hi!
I am beginner in "Gumbo Parser Library" and I have seen the examples of that but still I have issues with getting the text of the nodes.

How can I do that?!

Thanks.

My HTML code is like this:

1
2
3
4
 
<dl class="dl-horizontal">
	<dt>Email Address</dt>
	<dd>HelloWorld@Gmail.Com</dd>
</dl>


I need to get "HelloWorld@Gmail.Com" text.

I wrote this code:

1
2
3
4
5
6
7
8
9
10
11

#include "gumbo.h"
#include <stdio.h>
#include <string>

using namespace std;

			GumboNode* dt_first_child = static_cast<GumboNode*>(dt_children->data[0]);

			{
				printf("FOUND EMAIL ADDRESS");
			}
		}

		GumboVector* children = &node->v.element.children;

		for (unsigned int i = 0; i < children->length; ++i)
		{
			find_email(static_cast<GumboNode*>(children->data[i]));
		}
	}
}

string read_file(const char* filename)
{
	ifstream in(filename, ios::in | ios::binary);

	if (!in) {
		printf("File '%s' not found.", filename);
		exit(EXIT_FAILURE);
	}

	string contents;
	in.seekg(0, ios::end);
	contents.resize(in.tellg());
	in.seekg(0, ios::beg);
	in.read(&contents[0], contents.size());
	in.close();

	return contents;
}

int main(int argc, const char *argv[])
{
	if (argc != 2)
	{
		printf("Usage: LetsParse <filename>\n");
		exit(EXIT_FAILURE);
	}

	const char* filename = argv[1];
	string contents = read_file(filename);

	GumboOutput* output = gumbo_parse(contents.c_str());

	find_email(output->root);

	gumbo_destroy_output(&kGumboDefaultOptions, output);

	return 0;
}


But I don't know how to get the next element?!

<dd> is a sibling of <dt> not a child. You need to find the <dl> node and then the second child.
