string replacer in javascript

[ombrenelcielo]

Hi all,
I am doing some research in my spare time to write a small script that checks and modifies logs written in XML..

Logs have this format:

<value="sometexthere">
      <text>this is a place mark %%==here==%%</text>
</value>

What I am trying to achieve is to have a solution to replace a fixed place mark %%==here==%% with what stored in the element value.

I know that's very simple in perl and it's not a problem for me to script it in that language, but I wanted to ask you what could be a smart way to do it in javascript.

I guess I could use something like .replace(/%%==here==%%/, to capture the place holder, but then I would need to grab the value as element to put it in the replace function.
And being XML and not html I of course can't use getelementby... to grab my value=""

Any help appreciated 🙂

Javascript can be used with XML: http://www.w3schools.com/xml/tryit.asp?filename=tryxml_dom_getelement

But since there are no IDs for your elements, you're going to have to use getElementsByTagName and then iterate through them (if there are more than one).

Ok! That's an useful information!

In the end I've opted to write a script in perl to parse the files, much easier.
I'll get my hands on this whenever I will have time 🙂
