How to scrap content from a remote dynamic url

[Ramdas S]

Hello,

I am looking at ways I can scrap the content of a remote url and make
that available as a javascrpt string to a program running under
another domain.

I am able to easily scap contents of local files. But unable to parse
a URL. Is it that Javascript do not support such code?

I am fairly new to JavaScript and is more familiar with server side
scripting/prohgramming languages.

I am trying to write an application that will read data which can be
made available as dynamically generates XML files of similar schemas.
And then the same data be made available to serveral web sites running
on PHP/ASP/ASP.net across many servers. I know that it is possible to
do the same using server side technologies, but a common set of client
side scripts that are platform independent make sense.

Any advice/help is most appreciated

You can't. It is a cross-domain security issue.

It doesn't support cross-domain scripting such as you are trying to do.

Server side scripting is your best alternative.

Have a page on your server, call it "readTheFiles.php", then have
readTheFiles.php read the remote files, generate the XML files, and then
the "several web sites" can refer to that file. Give it a parameter that
is the URL to the remote file to read.
