[Htmlparser-user] HTML parser project question

[Ray J. <ra...@mc...>]

I am working on a project and am having a bit of trouble figuring out 
how to do what I want with the HTML parser.
Basically what I want to do is parse a HTML file and find all the 
text boxes. I then want to read the ID attribute of each box and load 
a value into the value attribute and reload the html file.

I am working on a program (Program A) that currently communicates 
with a micro controller. Program A communicates over RS 485 or 
ethernet. The communication part is complete and working. I make 
requests to the micro for information and also send updates to it. 
Program A currently displays information it receives from the micro 
in a tabular format. I created the GUI in Swing to display the 
information and allow the user to make changes to the system.

What I am currently trying to accomplish is this. We would like to 
display the information in a web page with a graphic representation 
of the HVAC system being monitored. The client will produce an HTML 
page with said graphic representation and text boxes that are to be 
updated with particular sensor, setpoint and relay values of the 
clients choice.The current values are to be obtained from the micro . 
The ID of the sensor, setpoint of relay to be updated in each text 
box will be stored in the input tags ID attribute. The HTML page will 
be stored locally on the clients computer and Program A will load the 
HTML into a web browser when the client hit a button in Program A 
(which is connected to the micro).

Before loading the HTML into a web browser I need Program A to parse 
the HTML and determine which value to load into which text box. Once 
Program A determines the values to be loaded and where to put them, 
it continually sends requests to the micro for the most updated 
values . Program A then updates the text boxes VALUE attribute with 
the correct value for that text box. I do need to continually update 
the text boxes and display the current value of the sensor, etc.

I am having an issue determining how to parse the HTML page to find 
the <input> tags and get the IDs I need as well as updating the VALUE 
attribute of that <input> tag continually from Program A.

I think that about covers it. If you have any questions , feel free 
to email me.
Thank you in advance,
Ray
