xmlns and html tags

Copy linkTweet thisAlerts:
Oct 03.2006

Greetings,

I’m currently developing an html application. part of this application involves parsing very large text files and producing formatted tables.

Parsing speed is becomng an issue, so now I’m looking for ways to reduce the amount of text being concatenated.

One of the major functions involve transforming each particular line as such:

Sample Line Before:

[CODE]XXX XXX ##### XX #### #### ##############XXX # XXX[/CODE]

After: (just 1 field shown as a sample)

[CODE]<tr><td oncontextmenu=’Lcon6(this)’><pre><a href=’#’ onclick=’STATDetail(Trim(this.innerText))’>XXX</a></pre></td></tr>[/CODE]

Its apparent that with larger and larger text files this function will get increasingly slow. Is there a way to reduce the output length without losing functionality? (besides changing the name of the functions to 1-2 digit names)
Perhaps xmlns is the answer? I haven’t used it enought to know its abilities in regards to something like this.

I'll rephrase the question. Is it possible to have xmlns attach events to an HTML tag that already exists, vice defining a new one? (attach to <td> instead of <myelement:td>). if so, how would this be accomplished? A simple link to an xmlns guide would suffice (hopefully one with more than 2 sentences....).

@TNOauthorOct 05.2006 — Nevermind, I figured it out. Instead of programmatically adding "onclick='SomeFunction()'" or other events to all 30,000 <td> tags, I used this instead:

[CODE]function addEvent(elm, evType, fn, useCapture) {
if (elm.addEventListener) {
elm.addEventListener(evType, fn, useCapture);
return true;
}
else if (elm.attachEvent) {
var r = elm.attachEvent('on' + evType, fn);
return r;
}
else {
elm['on' + evType] = fn;
}
}[/CODE]

@KorOct 05.2006 — I guess you might have used only the JSON statement. It is crossbrowser
<i>
</i>function addEvent(elm,evType,fn) {
elm['on' + evType] = function(){fn);
}


And I would have used the crossbrowser [B]Trim(this.firstChild.data)[/B] instead of Trim(this.innerText), which is IE only.

Success!
