Question

`generateCmponent` does not return anything Then look at the call order `generateCmponent` is called first adding the table After that the body is generated I would suggest that you return your table from the `generateCmponent` function and not append the writer

Thanks Tim hmm I know methods do not return anythig but operate on the writer Somehow I thought it is good idea to do like this without creating all dom in memory rather stream it I really tried to understand kolinx more as i like the DSL approach just could not find good example explaining how to do it

The StreamBuilder already immediatly appends to the stream and does not contain a collection of tags in memory So I guess this already works the way you intend it to work

Well i did what I thought you meant = Generate table into String writer and return String from generateComponent but it resulted in this lt html gt lt body gt amp lt table amp gt amp lt tr amp gt amp lt td amp gt xxx amp lt td amp gt amp lt tr amp gt amp lt tr amp gt amp lt td amp gt qf9e48t9u23849g amp lt td amp gt amp lt tr amp gt amp lt tr amp gt amp lt td amp gt uidddd00 amp lt td amp gt amp lt tr amp gt amp lt table amp gt d lt body gt lt html gt I maen including string into html structure gets escaped Could you please hint me more how to generate part of page and include into layout if you have a minute Thanks a lot

Okay I looked more into it It turns out you don t need to return anything from it as it does not build a DOM tree in memory You can add your HTML elements using a `HtmlBlockTag` as parent The follow code was refactored quite a bit so let s run through the changes I excluded the writer from the parameters where it is not needed anymore `generateCmponent` is now an extension function to `HtmlBlockTag` here <https github com Kotlin kotlinx html wiki Micro templating and DSL customizing> you have a little documentation on how to build functions that append the HTML `HtmlBlockTag` functions as parent to all of the HTML Tags I made the `this` calls explicit so you see immediatly when I m using an extension function ``` import kotlinx html import kotlinx html stream appendHTML import java io StringWriter import java io Writer fun HtmlBlockTag generateCmponent codes List lt String gt this table for code in codes tr td +code fun generateLayout writer Writer componentGenerator HtmlBlockTag gt Unit writer appendHTML html body this componentGenerator fun pageGenerate codes List lt String gt writer Writer generateLayout writer this generateCmponent codes fun main args Array lt String gt val codes = listOf xxx qf9e48t9u23849g uidddd00 val writer = StringWriter pageGenerate codes writer println writer toString ```
