Not a one liner but does the job

Code:
#!/bin/bash
i=1;f=0
while read line
do
  if [ "$line" == "<Placemark>" ]; then s=0; fi
  echo "$line" | grep "$1" >/dev/null 2>&1
  if [ $? -eq 0 ] && [ $f -eq 0  ] ;then f=1;fi
  if [ "$line" == "</Placemark>" ]; then s=1; fi
  x[$i]="$line"
  if [ $s -eq 1 ];then
    if [ $f -eq 0 ];then
      for((j=1;j<=i;j++))
      do
        echo ${x[$j]}
      done
    fi
    i=0;unset x;f=0
  fi
  ((i=i+1))
done < infile

Usage : script pattern

regards,
Ahamed
