[SOLVED] sed used to remove a line from xml file

nano2 · 10-25-2011, 04:13 AM

I have the following xml file where by i want to remove the following line from the file

This is what i have so far:

Code:

file.xml

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
&lt;!DOCTYPE data PUBLIC &quot;   ....... &quot;
&lt;data1&gt;
&lt;data2&gt;
&lt;removeTxt value=&quot;1234567&2442_1==&quot; /&gt;
&lt;typeName=&quot;replace&quot; /&gt;
---
----

I am using sed to remove the following line "<removeTxt value="1234567&2442_1==" />" from the file.xml

Code:

    sed -i '/&lt;/removeTxt value=/<\/&gt;>/d' file.xml

But this doesn't seem to remove the line. Can anyone spot why not ?

Your syntax appears to be off. Also the backslash toward the end needs to be escaped or sed will read as a deliminator. I have escaped below,with a bold /.

syntax

sed -i '/regex/d'

Quote:

sed -i '/<removeTxt value="1234567&2442_1==" //>/d'

Code:

sed '/removeTxt value/d'

This will remove every line that contains 'removeTxt value'. If the results look ok then invoke 'sed' with the -i option to make the changes permanent.

With the below i am getting
sed: -e expression #1, char 28: expected newer version of sed

[code]
sed 'removeTxt value/d' file.xml
[\code]

using GNU sed version 4.1.5

Any ideas ?

Sorry, my bad. It should be

Code:

sed  '/removeTxt value/d' file.xml

I also corrected in in my previous post.

Missing leading slash in the command above:

Code:

sed '/removeTxt value/d' file.xml
