@Kian I will just post this Regex, it is not the solution but I think it’s somewhere close to the Solution. Others can maybe enhance this regex or if this regex works on your PDF data and if it will only target the Director names (almost) for most of the PDF input files that you have, we can move forward and then discuss about the Format of the Word that comes after the name, so that you can make the necessary Group and extract it.
Check this Regex :
Anil_G
ashokkarale
Ajay_Mishra
Gautham_Pattabiraman
BHUSHAN_NAGAONKAR1
vrdabberu
ABHIMANYU_THITE1
lrtetala
samantha_shah
shyamala_shyamu
