Capture opening but not the closing tag

I want to segment a parent block, while capturing nested tags along each segment's text:

(?<tag>.)(?: href="(?<url>.+?)")?>(?<text>.+?)<

it works, but I want the "tag" to be empty in segments that aren't wrapped in a tag, however with the current reg., these capture the preceding segment's closing tag...

Live sample: https://regex101.com/r/UEZAaw/3/

The result set I would like to obtain, note that item 2 and 4 should have null for the tag:

{
   "0":{
      match: "p>The <",
      tag: "p",
      url: null,
      text: "The "
   },
   "1":[
      match: "a href=\"https://www.legislation.gov.uk/ukpga/2010/23/contents\">UK Bribery Act<",
      tag: "a",
      url: "https://www.legislation.gov.uk/ukpga/2010/23/contents",
      text: "UK Bribery Act"
   ],
   "2":[
      match: "/a> (“the Act”) received Royal Assent in April 2010 and came into ... <",
      tag: null
      url: null,
      text: " (“the Act”) received Royal Assent in April 2010 and came into ... "
   ],
   "3":[
      match: "a href=\"http://www.oecd.org/daf/anti-bribery/ConvCombatBribery_ENG.pdf\">OECD anti-bribery Convention<",
      tag: "a",
      url: "http://www.oecd.org/daf/anti-bribery/ConvCombatBribery_ENG.pdf",
      text: "OECD anti-bribery Convention"
   ],
   "4":[
      match: "/a>. The Act outlined four prime offences, including the introduction ... <",
      tag: null,
      url: null,
      text: ". The Act outlined four prime offences, including the introduction ... "
   ],
   "5":[
      match: "b>rest is history<",
      tag: "b",
      url: null,
      text: "rest is history"
   ]
   ...
}

How can I fix this?

I think this works, based on what I see in the MATCH INFORMATION box on regex101:

/(?:(?<tag>(?<!\/).)|(?:\/.))(?: href="(?<url>.+?)")?>(?<text>.+?)</gm
