Windows batch file to find variable string in html file

Question

I am trying to write a Windows batch file that will look at a specific html file that looks something like this: (/)>

            <input name="pattern" value="*.var" type="text" /><img style="width: 16px; height: 16px; vertical-align:middle; cursor:pointer" onclick="this.parentNode.submit()" class="icon-go-next icon-sm" src="/static/474743c8/images/16x16/go-next.png" /></form></div><table class="fileList"><tr><td><img style="width: 16px; height: 16px; " class="icon-text icon-sm" src="/static/474743c8/images/16x16/text.png" /></td><td><a href="./address.var.varapplication-varapplication-varwebservice-05.05.07-SNAPSHOT.var">address.var.varapplication-varapplication-varwebservice-05.05.07-SNAPSHOT.var</a></td><td class="fileSize">133.49 MB</td><td><a href="./address.var.varapplication-varapplication-varwebservice-05.05.07-SNAPSHOT.var/*fingerprint*/"><img style="width: 16px; height: 16px; " class="icon-fingerprint icon-sm" src="/static/474743c8/images/16x16/fingerprint.png" /></a> <a href="./address.var.varapplication-varapplication-varwebservice-05.05.07-SNAPSHOT.var/*view*/">view</a></td></tr><tr><td style="text-align:right;" colspan="3"><div style="margin-top: 1em;"><a href="./*.var/*zip*/target.zip"><img style="width: 16px; height: 16px; " class="icon-package icon-sm" src="/static/474743c8/images/16x16/package.png" />

and use the build version (for example, 05/05/07-SNAPSHOT - next time there will be a different version, but the format will remain the same), as a variable for another batch file. I tried with findstr but did not succeed:

for /F "delims=" %%a in ('findstr /ic "webservice" a.html') do set "line=%%a"
set "line=%line:*webservice=%"
for /F "delims=" %%a in ("%line%") do set string=%%a
for %%b in ("%line%") do @ set "var=%%b"
SET build=%var:~-11,8%      
ECHO. %build%

    html = file.ReadAll();

file.Close();
htmlfile.write('<meta http-equiv="x-ua-compatible" content="IE=9" />' + html);

var anchors = htmlfile.querySelectorAll('table.fileList a');

for (var i = 0; i < anchors.length; i++) {
    if (/webservice-((\d+\.)*\d.+)\.var$/i.test(anchors[i].href)) {
        WSH.Echo('build=' + RegExp.$1);
        WSH.Quit(0);
    }
