Re: Problems when copying files

It doesn't seem like the spec specifies whether an implementation should
creating any missing parent directories[1] so I don't know what is to be
expected. Maybe something like <p:store mkdirs="true|false" .../> could be
useful?

Since there's no "top-to-bottom" execution order in XProc, you're not
guaranteed that the copy operation from xml/ to xml1/ is completed before
the copy operation from xml1/ to xml2/.

AFAIK there's no multi-threading in calabash yet so the execution order for
a script when running it through calabash is the same every time if you run
it, and usually it executes bottom to top (it seems). So in your script,
all files from xml1/ will be copied to xml2/ *before* the files in xml/ is
copied to xml1/, which means there will be no files copied from xml1/ to
xml2/ at first run.

To make sure that you only load a file *after* the file is stored, you can
force a dependency between two steps by connecting it to a port or option
on the step that has a dependency:
<p:store href="test.xml" name="store1"/>
<p:load>
    <p:with-option name="href" select="'test.xml'">
        <p:pipe step="store1" port="result"/>
    </p:with-option>
</p:load>

Calabash also has the cx:depends-on="step-name" attribute to simplify
things:
<p:store href="test.xml" name="store1"/>
<p:load href="test.xml" cx:depends-on="store1"/>
