[SOLVED] sed; string with file

Dragon707 · 2014-11-11 15:46:43

Hi,

Is it possible the to replace a string with file contents, for example; i have the following XML file:

<?xml version="1.0" encoding="UTF-8"?>
<modification>
    <id>Testing</id>
    <version>0.0.1</version>
    <vqmver required="true">2.5.0</vqmver>
    <author><![CDATA[Dragon707]]></author>

    <file name="template/a.tpl">
        <operation error="log">
            <search position="before"><![CDATA[
                whooo
            ]]></search>
            <add><![CDATA[
                @include[src/script_whooo.js]
            ]]></add>
        </operation>
    </file>

    <file name="template/b.tpl">
        <operation error="log">
            <search position="before"><![CDATA[
                wheee
            ]]></search>
            <add><![CDATA[
                @include[src/script_wheee.js]
            ]]></add>
        </operation>
    </file>
</modification>

And the file src/script_whooo.js contains:

alert(1);

And the file src/script_wheee.js contains:

alert(2);

What i want is that the string "@include[src/script_whooo.js]" replaces the content with src/script_whooo.js. The expected output is then:

<?xml version="1.0" encoding="UTF-8"?>
<modification>
    <id>Testing</id>
    <version>0.0.1</version>
    <vqmver required="true">2.5.0</vqmver>
    <author><![CDATA[Dragon707]]></author>

    <file name="template/a.tpl">
        <operation error="log">
            <search position="before"><![CDATA[
                whooo
            ]]></search>
            <add><![CDATA[
                alert(1);
            ]]></add>
        </operation>
    </file>

    <file name="template/b.tpl">
        <operation error="log">
            <search position="before"><![CDATA[
                wheee
            ]]></search>
            <add><![CDATA[
                alert(2);
            ]]></add>
        </operation>
    </file>
</modification>

Yes, the read command "r" will read in a named file into the pattern space after the addressed line (which you then delete to replace):

/address/r filename
/address/d

You'll need to escape the special characters in your address.

I don't think you can get the filename from the file into the 'r' command of sed without naming the filenames explicitly.
Try this in bash:

while read; do
[[ "$REPLY" =~ ^(.*)@include\[([^\]]*)\](.*)$ ]] &&
REPLY=${BASH_REMATCH[1]}$(cat "${BASH_REMATCH[2]}")${BASH_REMATCH[3]}
echo "$REPLY"
done < script.xml

It only does one @include[] per line though.

You can name them explicitly, and use the pattern to select which to use.
Pretty sure you can also, if you wrap your sed script in a shell script, pass in the relevant names:

sed '/pattern1/r '"$1"'
       /pattern1/d
       /pattern2/r '"$2"'
       /pattern2/r' inputfile

Can't find a script where I do that at the moment though (except in awk).

EDIT: found one where I do that in the pattern space, so yeah, it should work.

Thanks for your answer, i got it to work however, i still miss the tabs in the output.xml file. Is there a way to keep the tabs in the output.xml?

#!/bin/bash

INPUT="input.xml"
OUTPUT="output.xml"

echo "" > $OUTPUT
while read; do
    [[ "$REPLY" =~ ^(.*)@include\[([^\]]*)\](.*)$ ]] &&
    REPLY=${BASH_REMATCH[1]}$(cat "${BASH_REMATCH[2]}")${BASH_REMATCH[3]}
    echo $REPLY >> $OUTPUT
done < $INPUT

Keep the quotes with the command echo "$REPLY".
If an included file has multiple lines, you can give all lines indentation with sed:

INPUT=input.xml
OUTPUT=output.xml
while read; do
[[ "$REPLY" =~ ^(.*)@include\[([^\]]*)\](.*) ]] &&
REPLY=$(sed "s/^/${BASH_REMATCH[1]}/" "${BASH_REMATCH[2]}")${BASH_REMATCH[3]}
echo "$REPLY"
done < $INPUT > $OUTPUT

Thanks! That did the trick

If I am processing an xml file in a shell script then I tend to use xmlstarlet. Makes things simpler and is ultimately more robust. It's in the standard community packages.
