asp取html代码中的所有图片为数组
<%
Function getIMG(sString)
Dim sReallyDo, regEx, iReallyDo
Dim oMatches, cMatch
'//定义一个空数组
iReallyDo = -1
ReDim aReallyDo(iReallyDo)
If IsNull(sString) Then
getIMG = ""
Exit Function
End If
'//格式化HTML代码
'//将每个 <img 换行 方便正则替换
sReallyDo = sString
On Error Resume Next
sReallyDo = Replace(sReallyDo, vbCr, " ")
sReallyDo = Replace(sReallyDo, vbLf, " ")
sReallyDo = Replace(sReallyDo, vbTab, " ")
sReallyDo = Replace(sReallyDo, "<img ", vbCrLf & "<img ", 1, -1, 1)
sReallyDo = Replace(sReallyDo, "/>", " />", 1, -1, 1)
sReallyDo = ReplaceAll(sReallyDo, "= ", "=", True)
sReallyDo = ReplaceAll(sReallyDo, "> ", ">", True)
sReallyDo = Replace(sReallyDo, "><", ">" & vbCrLf & "<")
sReallyDo = Trim(sReallyDo)
On Error GoTo 0
Set regEx = New RegExp
regEx.IgnoreCase = True
regEx.Global = True
'//去除onclick,onload等脚本
regEx.Pattern = "\s[on].+?=([""|\'])(.*?)\1"
sReallyDo = regEx.Replace(sReallyDo, "")
'//将SRC不带引号的图片地址加上引号
regEx.Pattern = "<img.*?\ssrc=([^""\'\s][^""\'\s>]*).*?>"
sReallyDo = regEx.Replace(sReallyDo, "<img src=""$1"" />")
'//正则匹配图片SRC地址
regEx.Pattern = "<img.*?\ssrc=([""\'])([^""\']+?)\1.*?>"
Set oMatches = regEx.Execute(sReallyDo)
'//将图片地址存入数组
For Each cMatch in oMatches
iReallyDo = iReallyDo + 1
ReDim Preserve aReallyDo(iReallyDo)
aReallyDo(iReallyDo) = regEx.Replace(cMatch.Value, "$2")
Next
getIMG = aReallyDo
End Function
response.write getIMG("&<DIV ALIGN=CENTER><IMG SRC=/UPLOADFILES14/200734194029734.JPG BORDER=0></DIV><DIV ALIGN=CENTER><IMG SRC=/UPLOADFILES14/200734194029734.JPG BORDER=0></DIV>&")
%>
我在网上找到的代码,执行不出来是什么原因?
[解决办法]
response.write参数不能为数组，会报错
arr=getIMG("&<DIV ALIGN=CENTER><IMG SRC=/UPLOADFILES14/200734194029734.JPG BORDER=0></DIV><DIV ALIGN=CENTER><IMG SRC=/UPLOADFILES14/200734194029734.JPG BORDER=0></DIV>&")
for i=0 to ubound(arr)
response.write arr(i)&"<br/>"
next
