Re: PULL Parser in PHP

Alek

Good I'll see your work by monday and send ideas/suggestions thinking
about a XSLT implementation. I guess that the XML test docs should be
delivered as strings maybe in CDATA sections of the XML test vocabulary.

Then it will be easy to write a XSLT stylesheet , something like this:

<test name="initial test">
<xmlsource><![CDATA[ <foo></foo> ]]>
<testCode>
<createParser/>
<setFeature name="BLAH" value="blah />
<expect type="START_DOCUMENT" nameNS="" localname="" />
<execute method="next()"/>
<expect type="START_TAG" nameNS="" localName="foo">
<execute method="isEmptyElement()" into="t1" />
<assertVar name="t1" value="true" />
<execute method="next()"/>
<expect type="END_TAG" nameNS="" localName="foo" />
<execute method="next()"/>
<expect type="END_DOCUMENT" nameNS="" localName="" />
</testCode>
</test>

For methods returning values we can use
<execute method="getName()" into="foo">
<assertVar name="foo" value="root">

execute executes a method and if into is defined assigns the return
value of the method to the variable indicated by name in the into
attribute.

into indicates the name of a variable, assertVar tests if a variable
has the desired value if not it throws an exception.

Then a test case is easy to run if no exceptions then test=ok ,
exceptions may come from the parser (example an expect that fails) or
from failed asserVars.

It will be important to keep the test vocabulary as minimalistic as we
can so the XSLT stylesheets are simple and easy to write allowing test
cases in many different languages.

Just some thoughts for you to start
