Title: thtmldocument get text nodes
Post by: BubikolRamios on June 13, 2019, 06:40:06 am

Code: Pascal  [Select][+][-]

1. ...
2. <a>foo</a><a>foo1</a>
3. ...
4.  

something like
pseudocode:

Code: Pascal  [Select][+][-]

1. TDomNodeList := thtmldocument.GetTextNodes()

would return element list  foo,foo1

Is there something like that ?

A solution without THtmlDocument: https://forum.lazarus.freepascal.org/index.php/topic,43090.msg301176.html#msg301176

Afaik this is walking the tree and looking for attribute #text in the dom nodes.  Code in compilelatexchm.pp in the "fpcdocs" repository does something like that.

To clarify, I don't need complete text, thtmldocument.TextContent already does that.


Examlple: have a list of elements and modify them inside thtmldocument

Code: Pascal  [Select][+][-]

1.     domNodeList:= thtmldocument.GetElementsByTagName('img');
2.     for i := 0 to domNodeList.Count-1 do
3.     begin
4.        tdomelement(domNodeList[i]).SetAttribute('src',someString);
5.     end;
6.  

so needed something instead of

Code: Pascal  [Select][+][-]

1. thtmldocument.GetElementsByTagName('img');
2.  

To get me text elements. need to modify them one by one, by regex replace in place, inside thtmldocument .
