Example 1-6 |
The right-hand side of the 'let' statement refers to 'named'. Should that be 'name'?
let $name := $product/named
vs.
let $name := $product/name

Second paragraph from bottom |
The end of the sentence should read "h1 element" not "ul element", so the sentence is "The content outside
the curly braces, namely the strings "There are " and " products." appear literally in the results, as
textual content of the h1 element.

2nd paragraph in "Useful Function" box |
The description of the function states that it performs a "value comparison", but the source code shows it as performing a "general comparison".

Table 3-5 |
There is an extra space in the path expression in the third row of the first column of Table 3-5. I think
it should be:
not(doc("catalog.xml")/catalog/product)

Table 4-4 |
In Table 4-4 of page 45
child::product/descendant::name = product//name
However on the end of page 48 it states that there is difference between
doc("catalog.xml")/catalog/descendant::name[1]
and
doc("catalog.xml")/catalog//name[1]
Is here not a conflict?
Note from the Author or Editor:
Adding the [1] changes things. The two examples from Table 4-4 do return the same result. Once you add the [1], though, you are talking about the first item that is returned by the step. In the first case, all the descendants are returned by the step at once, so the first item is the first name descendant anywhere in the document. In the second case, each name element is returned by the step individually, as a child of its parent, so you only get the name children that are first child in each parent.
Technically, to be more of an exact comparison, Table 4-4 should say:
child::product/descendant-or-self::*/name = product//name

line 6-7 |
Page 79, line 6-7: It is erroneous, or at least misleading,
to say that a variable
"should not be referenced in the let clause itself, as in:
let $count := $count + 1
". The above does not refer to the variable $count that is
being declared. According to Section 3.8.1 of the XQuery 1.0
Recommendation, "The scope of a variable bound in a for or let clause
[...] does not include the expression to which the variable is bound."
Thus, the right-hand side of the above let clause either (a) refers to a
previously declared $count variable or (b) it is
erroneous (XPST0008: Variable $count has not been declared).
Note from the Author or Editor:
The end of the first paragraph on page should be changed from "and it should not be referenced in the let clause itself, as in:" to "and it cannot be referenced in the let clause itself, as in:" (should not --> cannot). Also, the first sentence of second paragraph should be changed from "This is not illegal, but it will have unexpected..." to "This is not illegal, but it is actually declaring a new variable with the same name, so it will have unexpected..." |

1st paragraph |
(matches($prod/name, 'F.*') or matches($prod/name, 'G.*'))
should be
(matches($prod/name, '^F') or matches($prod/name, '^G'))
F.* => ^F
G.* => ^G
Note from the Author or Editor:
Yes, and two examples later there is another place where "F.*" should be changed to "^F". |
