processing html file

jin · Aug 2, 2001

i posted this on a different forum, but it's probably more appropriate here:

I have a short project...basically, I have a HashMap with several words in it. I also have a input html file with some text in it.

My project is that I have to make a new file...which has the same contents has the input file, BUT if any of the words from the Map shows up in the inputfile, I have to make those words hyperlinks.

For example, if the word "computer" is in the hashmap...and "The computer has 128 megs of RAM" is in the input.html file...i would create a new html file that says "The computer has 128 megs of RAM" -- BUT here 'computer' would be a hyperlink. (Thus, in the end, I would have a new HTML file which would have links to all words in the hashmap.)

I realllllllllllly need help here. I bet to many of you this is a simple problem!

( In the hashmap the key is the word, and the value is the hyperlink code. )

Hello,
I don't know the format of your hash table.
I'll suggest a client-side solution.
You will need 3 files:
input.js - with input html inside.
hashmap.js - with an assosiative array
output.html - with transformation function

input.js
===============
str = "<HTML>\n"
str += "<HEAD>\n"
str += "<TITLE> Input file </TITLE>\n"
str += "</HEAD>\n"
str += "<BODY>\n"
str += "There is a computer.<br>\n"
str += "Search Yahoo.\n"
str += "Search Google.\n"
str += "</BODY>\n"
str += "</HTML>\n"

hashmap.js
==============
hashmap = new Array();
hashmap['Yahoo']='

http://www.yahoo.com/';

hashmap['Google']='

http://www.google.com/';

hashmap['computer']='

http://www.computer.com/';

output.html
==============

<HTML>
<HEAD>
<TITLE> HashMap </TITLE>
<script language="JavaScript" src="hashmap.js"></script>
<script language="JavaScript" src="input.js"></script>
<script language="JavaScript">
function transform(){
for (ind in hashmap) { // ind is index from hashmap
if (str.indexOf(ind)!=-1) { // there is an ind substring in input file
lnk = "<a href='" + hashmap[ind] + "'>" + ind + "</a>";
str = replaceString(ind,lnk,str);
}
}
document.write(str);
}
function replaceString(oldS,newS,fullS) {
// Replaces oldS with newS in the string fullS
begin = fullS.indexOf(oldS); // begin of replacement
end = begin + oldS.length; //end of replacement
fullS = fullS.substring(0,begin) + newS + fullS.substring(end, fullS.length)
return fullS
}
</script>
</HEAD>

<BODY onLoad="transform()">

</BODY>
</HTML>
