[1] This should work fine:
---
<get context="$implicitElement/@srcfile" expression="resolve-uri(.)"/>
<command name="XXE.edit" parameter="%_"/>
---
because the <get> element returns a value and because the last returned
value is always available in the "%_" variable.
[2] Now let's make the problem more complicated by adding the ID found
in $implicitElement/@Idref.
This *could* have worked:
---
<set variable="theId" expression="$implicitElement/@Idref"/>
<get context="$implicitElement/@srcfile" expression="resolve-uri(.)"/>
<command name="XXE.edit" parameter="%_"/>
<get expression="$theId" />
<command name="selectById" parameter="id %_" />
---
However, it will *not* work because a command cannot switch its context
from a document to another document.
--> Explanations:
The command is executed in the context of doc1.xml. doc1.xml references
doc2.xml#foo. We want to open doc2.xml and then jump to the element
contained in doc2.xml having "foo" as its ID.
---
<!-- we are in doc1.xml -->
<set variable="theId" expression="$implicitElement/@Idref"/>
<!-- theId now contains "foo" -->
<get context="$implicitElement/@srcfile" expression="resolve-uri(.)"/>
<command name="XXE.edit" parameter="%_"/>
<!--XXE has opened doc2.xml in another window
but the macro still works on doc1.xml-->
<get expression="$theId" />
<command name="selectById" parameter="id %_" />
<!-- Fails: doc1.xml contains no element having "foo" as its ID-->
