hello
can any tell my a example on how to decode html and view the text in the html on the serial monitor?
thanks
can any tell my a example on how to decode html
html isn't encoded, so no decoding is needed.
and view the text in the html on the serial monitor?
html IS text, so just print it to the serial port.
I suspect that you mean that you want to parse html (not decode) and extract data from between some tags, and display only that text. But, you need to be far more specific.
yes, i will parse it.
know any a example?
i will that text written in the html in the arduino monitor with no and etc.
You need to show an example of the web page you are trying to parse, what data you want from the web page, and what code you have so far.
i will encode things as:
<html>
<h2>example</h2>
<p>test</p>
<p>hello</p>
<button type="button">Click Me!</button>
</html>
if it is posible,
can any tell my how to parse this and view it in the console or in a selfmade program?
but i will that arduino parse it, not my pc or laptop.
can any help my
If the web page is small, you might use client code like below. If the web page is large, you will need to use a streaming capture method such as Textfinder.
//zoomkat 11-04-13
//simple client test
//for use with IDE 1.0.1
//with DNS, DHCP, and Host
//open serial monitor and send an e to test
//for use with W5100 based ethernet shields
//remove SD card if inserted
//data from server captured in readString
#include <SPI.h>
#include <Ethernet.h>
String readString;
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; //physical mac address
char serverName[] = "web.comporium.net"; // zoomkat's test web page server
EthernetClient client;
//////////////////////
void setup(){
if (Ethernet.begin(mac) == 0) {
Serial.println("Failed to configure Ethernet using DHCP");
// no point in carrying on, so do nothing forevermore:
while(true);
}
Serial.begin(9600);
Serial.println("client readstring test 11/04/13"); // so I can keep track of what is loaded
Serial.println("Send an e in serial monitor to test"); // what to do to test
}
void loop(){
// check for serial input
if (Serial.available() > 0) //if something in serial buffer
{
byte inChar; // sets inChar as a byte
inChar = Serial.read(); //gets byte from buffer
if(inChar == 'e') // checks to see byte is an e
{
sendGET(); // call sendGET function below when byte is an e
}
}
}
//////////////////////////
void sendGET() //client function to send/receive GET request data.
{
if (client.connect(serverName, 80)) { //starts client connection, checks for connection
Serial.println("connected");
client.println("GET /~shb/arduino.txt HTTP/1.1"); //download text
client.println("Host: web.comporium.net");
client.println("Connection: close"); //close 1.1 persistent connection
client.println(); //end of get request
}
else {
Serial.println("connection failed"); //error message if no client connect
Serial.println();
}
while(client.connected() && !client.available()) delay(1); //waits for data
while (client.connected() || client.available()) { //connected or data available
char c = client.read(); //gets byte from ethernet buffer
readString += c;
//Serial.print(c); //prints each byte to serial monitor
}
//Serial.println();
Serial.println("Data from server captured in readString:" );
Serial.println();
Serial.print(readString);
Serial.println();
Serial.println();
Serial.println("End of readString");
Serial.println("client disconnecting.");
Serial.println("==================");
Serial.println();
client.stop(); //stop client
readString="";
}
thanks a lot.
but will that work with a enc28j60 that i have connected so: http://www.instructables.com/id/Cheap-and-Easy-Arduino-Wi-Fi-Hack/
and can u make a example for greater pages please?
