Question

I have this file (dev1.temp):

 <?xml version="1.0" encoding="UTF-8"?>
<krpano version="1.0.8.15" showerrors="false">

          <include url="include/sa/index.xml" /> <include url="content/sa.xml" />
          <include url="include/global/index.xml" />
          <include url="include/orientation/index.xml" />
          <include url="include/movecamera/index.xml" /> <include url="content/movecamera.xml" />
          <include url="include/fullscreen/index.xml" />
          <include url="include/instructions/index.xml" />
          <include url="include/coordfinder/index.xml" />
          <include url="include/editor_and_options/index.xml" />
</krpano>

The goal is to get all the url’s content and put them in a temp file (devel.temp). The output would be:

include/sa/index.xml
content/sa.xml
include/global/index.xml
include/orientation/index.xml
include/movecamera/index.xml
content/movecamera.xml
include/fullscreen/index.xml
include/instructions/index.xml
include/coordfinder/index.xml
include/editor_and_options/index.xml

To do the trick I have the following script:

# Make a temp file with all the files url's    
grep -o 'url=['"'"'"][^"'"'"']*['"'"'"]' $temp_folder"/devel1.temp" > $temp_folder"/devel2.temp"
# Strip off everything to leave just the url's'    
sed -e 's/^url=["'"'"']//' -e 's/["'"'"']$//' $temp_folder"/devel2.temp" > $temp_folder"/devel.temp"

Yesterday it worked perfectly. Today, devel2.temp and devel.temp output is this:

[01;31m[Kurl="include/sa/index.xml"[m[K
[01;31m[Kurl="content/sa.xml"[m[K
[01;31m[Kurl="include/global/index.xml"[m[K
[01;31m[Kurl="include/orientation/index.xml"[m[K
[01;31m[Kurl="include/movecamera/index.xml"[m[K
[01;31m[Kurl="content/movecamera.xml"[m[K
[01;31m[Kurl="include/fullscreen/index.xml"[m[K
[01;31m[Kurl="include/instructions/index.xml"[m[K
[01;31m[Kurl="include/coordfinder/index.xml"[m[K
[01;31m[Kurl="include/editor_and_options/index.xml"[m[K

Any ideas about what’s going on?

Seems like grep is using ANSI sequences to colour its output even when the output is not the terminal. Change its --color from always to auto.

Rather than using grep to process XML, you should use an XML-aware tool. For example, in xsh, you can write

open file.xml ;
perl { use Term::ANSIColor } ;
for /krpano/include
    echo :s { color('bright_yellow') }
            @url
            { color('reset') } ;
