regex

Hi,

I am hoping someone can help me with a regex.

I think it is pretty simple. I could probably cobble something together
using string manipulations, but I thought regex might be a more elegant
solution, but I dont have much experience with reg ex and I need to do this
ASAP.

Any help would be much appreciated.

I need to replace any instances of height="x" & width="x", with height="100"
& width="100", from a string.

Basically, I need to dynamically change the height and width that a youtube
video renders at within a browser.eg.

<object width="425" height="355"><param name="movie"
value="http://www.youtube.com/v/t9_TPM1lKV8&hl=en"></param><param
name="wmode" value="transparent"></param><embed
src="http://www.youtube.com/v/t9_TPM1lKV8&hl=en"
type="application/x-shockwave-flash" wmode="transparent" width="425"
height="355"></embed></object>

regex, to replace the height and width within this string to force a 100px
square. I will never know the size of the video a user wants to display, so
I can't use a standard replace.

I am using ASP & vbscript.

Any help would be much appreciated.

You could use a pattern like the one below (assume your HTML code is in
'sCode' variable):

Set oRegEx = CreateObject("VBScript.RegExp")
oRegEx.IgnoreCase = True
oRegEx.Global = True
oRegEx.Pattern = "(width|height)(.?=.?"")(\d*?)("")"
sCode = oRegEx.Replace(sCode, "$1$2100$4")

Dim rx
Dim html
Const SIZE_VH = "100"

Set rx = New RegExp
rx.Pattern = "(\b(width|height)="")([\d\.]+)("")"
rx.Global = true
rx.Ignorecase = true


html = "<object width=""425"" height=""355""><param name=""movie""" _
& "value=""http://www.youtube.com/v/t9_TPM1lKV8&hl=en"">" _
& "</param><param name=""wmode"" value=""transparent""></param>" _
& "<embed src=""http://www.youtube.com/v/t9_TPM1lKV8&hl=en""" _
& " type=""application/x-shockwave-flash"" wmode=""transparent""" _
& " width=""425"" height=""355""></embed></object>"

MsgBox rx.Replace (html, "$1" & SIZE_VH & "$4")
