Dynamic XHTML insertion in NetWebPage

[springguy]

NetTalk 6.42

I have a NetWebPage that I have been using with XHTML to incorporate a series of image Tiles with clickable links.  Works fine.

Now, I want to expand that capability by dynamically looking up the appropriate image tile and XHTML from a database rather than having it hard coded in the XHTML tab. 

I'll be looking up each image tile as a separate item from the database based on some selection coding, but once I have the appropriate record with the xHTML, how do I incorporate the xHTML into the page?  Embed point?

Thanks,

Hi Mike,

right click on the NetWebPage and choose "Source".
then you'll be able to see all the generated code, and the context.

Embedding then becomes a lot easier (simply embed "near" the xHtml generated bits.)

Thanks Bruce,
That was your typical wise advice.  I followed it and created my own routine that builds the packet with the desired xHTML from a database record.  That logic is pretty straight forward. 

But, I looked at the packet info that the template generates for xHTML that was added in the template and I see that you manipulate the xHTML.  For example, you add < in front of any < characters (like <<div id> whereas the xHTML is <div id>.  Also, you add <13,10> at the end of every line.

What I'm wondering is can I call a NT routine that does that modification to a line of xHTML (I could not find one), or do I have to write my own routine to mimic the changes that the template generates?

Hi Mike,

it's not really me, it's a Clarion template command (called QUOTE I think) which does that. Basically
it turns < into <<, { into {{, ' into '' and so on.

the <13,10> I think is just a convenience I add.

Early versions of clarion choked on < because < has a special meaning in a clarion string (so turning them into << is safer).
However later versions of clarion got smart and < will work ok, as long as it's not followed by a number.

If you wanted to replace < with << or whatever then I'd personally just use the StringTheory REPLACE command.
