i think easy don't have time learn how it.
in html file, have class of paragraph, let´s say:
<p class="footnote"></p> the "p" tag followed numbers, increase 1 in every instance. let's first number "43". want series of numbers start 1, need substract 42 paragraphs.
for example, want go from:
<p class="footnote">43. lorem</p> <p class="footnote">44. ipsum</p>. <p class="footnote">45. dolor</p>. to
<p class="footnote">1. lorem</p> <p class="footnote">2. ipsum</p>. <p class="footnote">3. dolor</p>. ¿how can it?
if you're looking regex that'll handle <p class="footnote">43. lorem</p> answer don't parse html regex.
assuming you've extracted string 43. lorem tag , want number out depends on requirements:
to find number: \d+
to find number @ beginning: ^\d+
to find number followed period: \d+\.
a more complete solution require more details problem including programming language want use.
