'用法:很多人都问我怎么用,其实数组怎么用的这个就怎么用.
sContent = "HTML代码字段" '//sContent代表Html代码，原来写个ors怎么就不懂是记录集呢。。。
Dim aImages : aImages = GetImg(sContent) '//定义一个数组,并且用来存放所有分析到的图片地址
'列出所有图片的地址:
For i = 0 To UBound(aImages)
    Response.Write("<b>第" & i + 1 & "张图片地址:</b> " & aImages(i) & "<br />")
Next
'列出第一张图片地址:
If UBound(aImages)> -1 Then Response.Write("<p><b>第一张图片地址:</b> " & aImages(0) & "</p>")
'列出最后一张图片地址:
If UBound(aImages)> -1 Then Response.Write("<p><b>最后一张图片地址:</b> " & aImages(UBound(aImages)) & "</p>")
