For read an xml embedded in app package at runtime you can use for example jquery whitout problem.
Yourxml.xml:
<?xml version="1.0" encoding="utf-8" ?>
<BookList>
<Book>
<Title>title one</Title>
<Publisher>Publisher one</Publisher>
</Book>
<Book>
<Title>Title two</Title>
<Publisher>Publisher two</Publisher>
</Book>
</BookList>
Reading:
$.ajax({
type: "GET",
url: "yourxml.xml",
dataType: "xml",
success: function(xml) {
$(xml).find('Book').each(function(){
var sTitle = $(this).find('Title').text();
var sPublisher = $(this).find('Publisher').text();
});
}
});
