Replace words on Safari iOS using a Content Blocker












0














In short:



Is it possible to replace words on Safari iOS using a Content Blocker?



In long:



I know how to block:




  • Cookies (with block-cookies)

  • Elements via CSS selectors (with css-display-none)

  • URLs or URLs containing specific text (with url-filter and regex)


But I'm looking to replace words - not hide them.

For the sake of clarity, one example can be: replace all instances of pizza with yum.



My current approach would be to:




  • Parse the user's webpage to JSON

  • Find all instances of pizza and replace them with yum.

  • Save the results as a new HTML or JSON file.


But then what? How would I show the resulting JSON/HTML to the user in the iOS Safari browser?



Is this at all possible, or do we only have access to CSS selectors?




Notes




  • Must I make my own browser?

  • No 'private' APIs (I'm looking to release this).

          Monumento 1, uma das quatro cabeças colossais encontradas em La Venta, com altura aproximada de 3 metros Olmecas é a designação do povo e da civilização que estiveram na origem da antiga cultura pré-colombiana da Mesoamérica e que se desenvolveram nas regiões tropicais do centro-sul do atual México durante o pré-clássico, próximo de onde hoje estão localizados os estados mexicanos de Veracruz e Tabasco, no Istmo de Tehuantepec, numa zona designada área nuclear olmeca. A cultura olmeca floresceu nesta região aproximadamente entre 1500 e 400 a.C., [ 1 ] e crê-se que tenha sido a civilização-mãe de todas as civilizações mesoamericanas que se desenvolveram posteriormente. [ 2 ] No entanto, desconhece-se a sua exacta filiação étnica, ainda que existam numerosas hipóteses colocadas para tentar resolver esta questão. O etnónimo olmeca foi cunhado pelos arqueólogos do século XX, e não devem confundir-se com os muito posteriores olmecas-xicalancas que ocuparam vários locais do México
