Assuming I have such an XML file:
<view>
<field table="alice" name="fish"/>
<field id="confirmation" controlType="button" enabled="some-condition">
<title>Confirm...</title>
</field>
<field table="bob" name="cat"/>
<field table="bob" name="dog" hidden="true"/>
</view>
I want to output all its fields, but the output is conditional on the attributes which are present.
Expected result:
field 'alice.fish'
button "Confirm..." (enabled: some-condition)
field 'bob.cat'
field 'bob.dog' (hidden: true)
Current result:
field 'alice.fish' (hidden: )
field '.' (hidden: )
field 'bob.cat' (hidden: )
field 'bob.dog' (hidden: true)
"" (enabled: )
button "confirm" (enabled: some-condition)
"" (enabled: )
"" (enabled: )
via 2 calls to XmlStarlet:
xmlstarlet sel -t -m "//field" -o "field '" -v "@table" -o "." -v "@name" -o "' (hidden: " -v "@hidden" -o ")" -n $1
xmlstarlet sel -t -m "//field" -v "@controlType" -o " \"" -v "@id" -o "\" (enabled: " -v "@enabled" -o ")" -n $1
Is is possible to turn the 3 different types of results inside 1 call to XmlStarlet, so that the fiels stay presented in their original order?
You need to use the --if option (--break indicates end of current control structure).
xmlstarlet sel --text -t -m "//field" \
--if "@controlType='button'" \
-v "@controlType" -o " \"" -v "title" -o "\" (enabled: " -v "@enabled" -o ")" \
--else \
-o "field '" -v "@table" -o "." -v "@name" -o "'" \
--if "@hidden" -o " (hidden: " -v "@hidden" -o ")" --break \
--break \
-n "$1"
