Reading a HTML file through Groovy Script - jenkins

Question

I need to write a Jenkins pipeline script using Groovy where the below HTML is the input.
<table style="width:30%">
<TR>
<TD>Failed A Count</TD>
<TD>2869</TD>
</TR>
<TR>
<TD>Failed B Count</TD>
<TD>9948</TD>
</TR>
<TR>
<TD>Failed C Count</TD>
<TD>3456</TD>
</TR></table>
I am getting it from a RestAPI, and if any of the value is more than 100 I need to trigger an email.
def response = httpRequest 'REST_API_URI'
println("Status: "+response.status)
def responseBody = response.content
String[] TDcollection;
String[] splitData = responseBody.split("\n");
for (String eachSplit : splitData) {
if (eachSplit.contains("Failed")) {
print(eachSplit);
}
}
I have tried this, But not able to pick up the value and validate it.
This might seem very easy, but as I am very
new to Groovy, I am kind of stuck on it. Thanks In Advance.

No-brainer groovy:
String input = '''\
<table style="width:30%">
 <TR>
 <TD>Failed A Count</TD>
 <TD>2869</TD>
 </TR>
 <TR>
 <TD>Failed B Count</TD>
 <TD>9948</TD>
 </TR>
 <TR>
 <TD>Failed B Count</TD>
 <TD>10000</TD>
 </TR>
 <TR>
 <TD>Failed C Count</TD>
 <TD>3456</TD>
 </TR></table>'''
Map<String,Integer> failedValues = [:].withDefault{ 0 }
input.eachMatch( /<TD>Failed (\w+) Count<\/TD>\s*<TD>(\d+)<\/TD>/ ){ _, name, count -> failedValues[ name ] += count.toInteger() }
assert failedValues == [A:2869, B:19948, C:3456]
boolean errorOccured = failedValues.any{ 100 <= it.value }
assert errorOccured
Note also the summing up of counts for the same "name".
