given your sample file myFile:
Code:
<string-array name="stringArray1">
<item>Element1|Element2<item>
<item>@android:color/black<item>
</string-array>
<style name="style1" parent="@android:style/mainStyle"></style>
<style name="style1" parent="@android:style/mainStyle">
<item name="android:textColor">@drawable/black</item>
<item name="android:typeface">sans</item>
<item name="android:textStyle">bold</item>
</style>
<string-array name="stringArray1">
<item>Element1|Element2<item>
<item>@android:color/black<item>
</string-array>
<string-array name="stringArray2"></string-array>

and the code:
Code:
nawk -F'"' '$1 ~ "=$" && NF>1 {f=($(NF-1) in a)?0:1;if(f)a[$(NF-1)]} f' myFile

I get:
Code:
<string-array name="stringArray1">
<item>Element1|Element2<item>
<item>@android:color/black<item>
</string-array>
<style name="style1" parent="@android:style/mainStyle"></style>
<item name="android:textColor">@drawable/black</item>
<item name="android:typeface">sans</item>
<item name="android:textStyle">bold</item>
</style>
<string-array name="stringArray2"></string-array>

looks fine to me. Anything wrong you can identify?

NAME
ppmtopgm - convert a portable pixmap into a portable graymap SYNOPSIS
ppmtopgm [ppmfile] DESCRIPTION
Reads a portable pixmap as input. Produces a portable graymap as output. The output is a "black and white" rendering of the original image, as in a black and white photograph. The quantization formula used is .299 r + .587 g + .114 b. Note that although there is a pgmtoppm program, it is not necessary for simple conversions from pgm to ppm , because any ppm program can read pgm (and pbm ) files automatically. pgmtoppm is for colorizing a pgm file. Also, see ppmtorgb3 for a different way of converting color to gray. And ppmdist generates a grayscale image from a color image, but in a way that makes it easy to differentiate the original colors, not necessarily a way that looks like a black and white photograph. QUOTE
Cold-hearted orb that rules the night Removes the colors from our sight Red is gray, and yellow white But we decide which is right And which is a quantization error. SEE ALSO
