How to Parse Xml Using Shellscript

How to parse XML using shellscript?

You could try xmllint

The xmllint program parses one or more
XML files, specified on the command
line as xmlfile. It prints various
types of output, depending upon the
options selected. It is useful for
detecting errors both in XML code and
in the XML parser itse

It allows you select elements in the XML doc by xpath, using the --pattern option.

On Ubuntu, if it is not already installed, you can run apt-get install libxml2-utils

How to parse an xml and get value using shell script

You can use this xmlstarlet command to extract the values:

xmlstarlet sel -t \
    -v '//module-option[@name = "userName"]/@value' \
    -nl \
    -v '//module-option[@name = "password"]/@value' \
  file.xml

and, assuming your shell is bash, to read those values into shell variables, use a Process Substitution:

{
    IFS= read -r userName
    IFS= read -r password
} < <(
    xmlstarlet sel -t -v '//module-option[@name = "userName"]/@value' -nl -v '//module-option[@name = "password"]/@value' file.xml  
)

echo "$userName"; echo "$password"

How to read XML and write to text file using shell script?

Try following and let me know if this helps you.

awk '
/<\/Data>/{
  a="";
  next
}
/<Data>/{
  a=1;
  next
}
/location/ && a{
  gsub(/\"|>/,"",$NF);
  location=$NF;
  next
}
/Name/ && a{
  name=$2;
  next
}
/ID/ && a{
  print "Name : ",name RS "ID: ",$2 RS "Location: ",location;
  next
}
'    Input_file

As per OP's request sine NO TAGS should be hard coded so adding following solution too now.

EDIT2: I am not a xml expert but tried it here, could you please check once.

awk 'NF==1 && (/ +<[a-zA-Z]+>/ || /^<[a-zA-Z]+>/ || / +<\/[a-zA-Z]+>/){
next
}
{
sub(/^ +/,"")
gsub(/\"|<|>/,"",$0);
sub(/\/.*/,"");
if($0){
  print
}
}
'  Input_file
