Loop through a HTML document

[nathan_roadshow]

Hi all, I'm trying to loop through various html's, e.g:

Through a local xlsx file which looks like below which is loaded in:

Channel	Channel_Links	Market	HD
ABC1	https://www.ontvtonight.com/au/guide/listings/channel/1990/abc1.html	Free TV	FALSE
ABC-HD	https://www.ontvtonight.com/au/guide/listings/channel/2984/abc-hd.html	Free TV	TRUE
ABC-COMEDY-ABC-KIDS	https://www.ontvtonight.com/au/guide/listings/channel/2043/abc-comedy-abc-kids.html	Free TV	FALSE
ABC-ME	https://www.ontvtonight.com/au/guide/listings/channel/2096/abc-me.html	Free TV	FALSE
ABC-NEWS	https://www.ontvtonight.com/au/guide/listings/channel/2149/abc-news.html	Free TV	FALSE
SEVEN	https://www.ontvtonight.com/au/guide/listings/channel/1639/seven.html	Free TV	FALSE
7-HD	https://www.ontvtonight.com/au/guide/listings/channel/2890/7-hd.html	Free TV	TRUE

Due to the webpage, i'm getting 'BAD GATEWAY', and then it will end the execution. I am also going through various HTML's and therefore random ones fail and interrupt the chain each time.

For example I am currently running:

For i = 1 to NoOfRows('AUChannelTable')

Let vURL = Peek('Channel_Links',($(i)-1),'AUChannelTable');
Let vChannel = Peek('Channel',($(i)-1),'AUChannelTable');
Let vChannelID = SubField(SubField(vURL,'channel/',2),'/',1);
Let vMarket = Peek('Market',($(i)-1),'AUChannelTable');
Let vHD = Peek('HD',($(i)-1),'AUChannelTable');

Table:
LOAD
now(1) as QVD_Load_Time
, '$(vChannel)' as Channel
, '$(vChannelID)' as CID
, '$(vMarket)' as Market
, '$(vHD)' as HD_Flag
, "Time"
, "TV Show"
, Date(Today(1))&'%'&'$(vChannelID)'&'%'&[TV Show]&'%'&"Time" as Key
FROM [$(vURL)]
(html, codepage is 28591, embedded labels, table is @1);

Next i

What would be the best way to write a loop to, if fails, repeat the attempt to access the html?

I will therefore be able to iterate through each row and if fail, retry?

Apologies for the difficult question but it has been bugging me!
