ASP.net: Read HTML and ASP.net Pages to Strings? - asp.net

Question

I am trying to write an aspx page which will crawl through a directory and find all the files contained within. I think I have that part down.
Is it possible to read to a string without first creating .txt files from the html and asp pages I'm reading through? I don't want to create a ton of new files and then end up having to delete them later.
Ultimately, I'm trying to develop a tool to search through an entire directory and find all the image tags which have empty alt attributes or no alt attributes. I wrote some jQuery which can find the tags, and I have also written the part that searches through a directory.

If you have a file on your filesystem, you can simply read it - if you know it is a textual format, you need to use a stream with the correct encoding to do this.
Since you are reading and querying HTML, I suggest using a library that is specifically written for this task - the HTML Agility Pack - you can give it the path to the HTML file and then query it for all img elements. The source download comes with sample projects that will show you how to achieve this and other tasks.

Example:

(this example shows how to work with .txt files, but I believe if you can put any other extension)

Edit: and don't forgot about encoding.

sure, why not save to environment variables, no fuss, no mess. so try something like this:
will take apart an html or asp file and save to an array of variables, i have shown you how to put it back together as well.
let me know how if this is a solution for you
#echo off
setlocal EnableDelayedExpansion EnableExtensions
echo.
set count=0
if exist newfile.html del newfile.html
:: to unassemble
for /f "tokens=*" %%a in (filename.html) do (
echo %%a
set /a count=count + 1
set htmllinenum!count!=%%a
)& set finalcount=!count!
:: to assemble
for /l %%a in (1,1,%finalcount%) do (
echo !htmllinenum%%a!>>newfile.html
)
notepad newfile.tmp
set count=0
if exist newfile.asp del newfile.asp
:: to unassemble
for /f "tokens=*" %%a in (filename.asp) do (
echo %%a
set /a count=count + 1
set asplinenum!count!=%%a
)& set finalcount=!count!
:: to assemble
for /l %%a in (1,1,%finalcount%) do (
echo !asplinenum%%a!>>newfile.asp
)
notepad newfile.asp
