I would like to extract version number from this string:

<a href="/url/version/tree/1.0.1alpha11" class="css-truncate">

Note that '/url/version/tree/' may change (ex: from /url/version/tree/ to /url/version2/tree1/) and version may change too (ex: from 1.01alpha11 to 2.0stable)

Ideas/suggestions?

sed solution:

Sample file input.txt:

<a href="/url/version/tree/1.0.1alpha11" class="css-truncate">
<a href="/url/version2/tree1/1.0.2alpha11" class="css-truncate">
<a href="/url/version/tree/2.0stable" class="css-truncate">

sed -En 's@.*<href="/[^[:space:]]+/([^/"[:space:]]+).*@1@p' input.txt

The output:

1.0.1alpha11
1.0.2alpha11
2.0stable

I extracted the version by using below awk command. As tested its worked fine.

Inputfile

<a href="/url/version/tree/1.0.1alpha11" class="css-truncate">
<a href="/url/version2/tree1/1.0.2alpha11" class="css-truncate">
<a href="/url/version/tree/2.0stable" class="css-truncate">

command

awk -F '[/]' 'print $NF' Inputfile| awk -F '"' 'print $1'

output

1.0.1alpha11
1.0.2alpha11
2.0stable

Source file: input.txt:

<a href="/url/version2/tree1/2.0stable" class="css-truncate">
<a href="/url/version/tree/1.0.1alpha11" class="css-truncate">
<a href="/url/version2/tree1/1.0.2alpha11" class="css-truncate">

Using awk and sed:

awk 'BEGIN FS = "/" print $5 ' input.txt | sed -E 's/^(.*)"s.*/1/'

Results:

2.0stable
1.0.1alpha11
1.0.2alpha11
