Hi Yoda,

Thank you very much.its working fine.But actual my input file is like below.
Code:
<?xml version='1.0' encoding='UTF-8'?>
<row_set>
<row_record>
    <a>testing1</a>
    <b>testing2</b>
    <c>testing3</c>
</row_record>
<row_record>
    <a>testing1</a>
    <b>testing2</b>
    <c>testing3</c>
</row_record></row_set><?xml version='1.0' encoding='UTF-8'?>
<row_set>
<row_record>
    <a>testing1</a>
    <b>testing2</b>
    <c>testing3</c>
</row_record>
<row_record>
    <a>testing1</a>
    <b>testing2</b>
    <c>testing3</c>
</row_record>
</row_set>

So it is replacing entire line when string eligible.

I want to replace exact string with out deleting other string.

how can i achieve this.

Thanks,
Madhu

Hi
Thank you yoda and 116@434.

With your help i have solved my probelm.

here is Solution for my probelm.

Code:
Solution1:
sed -e 's/<\?xml version='"'"'1.0'"'"' encoding='"'"'UTF-8'"'"'?>//' -e 's/<Cond_Tbl_Data_Set>//' -e 's/<\/Cond_Tbl_Data_Set>//'   ${FULL_DATA_PATH} >> ${OUT_FILE}
sed '/^$/d' <${OUT_FILE} >> ${OUT_FILE1}

Solution2:

sed -e "s:<?xml version='1.0' encoding='UTF-8'?>::" -e "s:</*Cond_Tbl_Data_Set>::" -e "/^$/d" ${FULL_DATA_PATH} >> ${OUT_FILE}

Solution 3 with AWK

awk '!/<?xml/&&!/<row_set/&&!/<\/row_set/'  INPUT_FILE.

But solution 3 is removing the entire line with the selected criteria.in my case sol1 & 2 working fine only by removing selected string.

These are not my solutions.

Thanks,
Madhu
