'用法:很多人都問我怎麼用,其實數組怎麼用的這個就怎麼用.
sContent = "HTML代碼字段" '//sContent代表Html代碼，原來寫個ors怎麼就不懂是記錄集呢。。。
Dim aImages : aImages = GetImg(sContent) '//定義一個數組,並且用來存放所有分析到的圖片地址
'列出所有圖片的地址:
For i = 0 To UBound(aImages)
  Response.Write("<b>第" & i + 1 & "張圖片地址:</b> " & aImages(i) & "<br />")
Next
'列出第一張圖片地址:
If UBound(aImages)> -1 Then Response.Write("<p><b>第一張圖片地址:</b> " & aImages(0) & "</p>")
'列出最後一張圖片地址:
If UBound(aImages)> -1 Then Response.Write("<p><b>最後一張圖片地址:</b> " & aImages(UBound(aImages)) & "</p>")
