php-html-safe 0.10.1-3build1 (ppc64el binary) in ubuntu xenial

 This parser strips down all potentially dangerous content within HTML:
  * opening tag without its closing tag
  * closing tag without its opening tag
  * any of these tags: "base", "basefont", "head", "html", "body", "applet",
    "object", "iframe", "frame", "frameset", "script", "layer", "ilayer",
    "embed", "bgsound", "link", "meta", "style", "title", "blink", "xml", etc.
  * any of these attributes: on*, data*, dynsrc
  * javascript:/vbscript:/about: etc. protocols
  * expression/behavior etc. in styles
  * any other active content
 .
 It also tries to convert code to XHTML valid, but htmltidy is far better
 solution for this task.
