Retrieving values from a page using the ESP8266 01 module - Arduino code

Help because I'm stuck, I want to retrieve a certain value from a page with the ESP8266 01 module with the following code:
.

this code gives "none"

Why don't you use the hardware Serial1 from Leonardo, which also happens to be available on pins 0 and 1? SoftwareSerial seems to be redundant.

See the Arduino SerialEvent example, it takes a while to send a character, with 9600 it's even a very long time, during this time the Arduino does thousands of checks if there is a character in the buffer and tries to print this text, it probably gets clogged up after a while. You have to collect the letters one by one into your buffer, make a line of text out of them (and it's good to send it in such a way that the message ends with a NL/CR character, which gives you information to do something with it now). And of course as khoam mentioned use hardware, then you can also set it to 115200 and it will be much faster.

Why is the same sequence of if statements repeated 2 times in the loop?

The first relates to the "availability" of packages in ESPSerial (i.e. SoftwareSerial), the second in Serial.

Can availability (available?) be in only one case? Do you have to check both?
