Applescript - парсинг XML

Я пытаюсь создать Applescript для извлечения значения из .xfdf

Applescript

set theXMLFile to ((choose file) as string)

tell application "System Events"
    tell XML element "xfdf" of contents of XML file theXMLFile
        set typeText to (value of XML element "p")
        set nameText to (value of XML element "p")
    end tell
end tell

Когда я запускаю скрипт, я получаю эту ошибку: Системные события получили ошибку: Не удалось получить элемент XML "p" элемента XML "xfdf" из содержимого файла XML. Есть ли где-нибудь я могу извлечь эти значения из XML. Значение для извлечения "popup", "p".

set theXMLFile to ((choose file) as string)
tell application "System Events"
    set theXMLFile to XML file theXMLFile
    set loops to XML elements of XML element "annots" of XML element "xfdf" of theXMLFile whose name is "square"
    set coor to {}
    repeat with i from 1 to (count loops)
        --set end of p to value of XML element "square" of XML element "body" of XML element "contents-richtext" of item i of squares
        set end of coor to value of XML attributes of XML element "square" of item i of loops
    end repeat

end tell
squares

Вы прямо спрашиваете xfdf элемент для p, но xfdf не является его родителем. Вам нужно копаться в иерархии, чтобы достичь ее.

set theXMLFile to ((choose file) as string)
tell application "System Events"
    set theXMLFile to XML file theXMLFile
    set squares to XML elements of XML element "annots" of XML element "xfdf" of theXMLFile whose name is "square"
    set p to {}
    set attrs to {}
    repeat with i from 1 to (count squares)
        set end of p to value of XML element "p" of XML element "body" of XML element "contents-richtext" of item i of squares
        set end of attrs to value of XML attributes of XML element "popup" of item i of squares
    end repeat
end tell
p --> {"Text Not Clear", "Incorrect dimension", "Incorrect Text"}
attrs --> {{"yes", "0", "453.5999999989341,944.4600000003926,573.5999999989341,1056.9600000003927"}, {"yes", "0", "550.7999999987057,1011.4200000002352,670.7999999987056,1123.9200000002352"}, {"yes", "0", "431.99999999898483,637.7400000011133,551.9999999989849,750.2400000011135"}}

Другой вариант - использовать дополнение XML Tools Scripting от Late Night Software.

Я написал рекурсивную вспомогательную функцию, которая может решить эту проблему.

Он ищет в xml конкретное имя и возвращает список элементов XML, которые вы можете затем перебрать, чтобы получить ваши значения.

Преимущество этого в том, что вам не нужно заранее знать абсолютные пути к Элементу.

Пример:

set theXMLFile to ((choose file) as string)

tell application "System Events"
    set xmlData to XML file theXMLFile

    set found_elements to my getXMLElementsByName("p", contents of xmlData)

    log ("Found " & (count of found_elements) & " <p> nodes")

    repeat with i from 1 to count of found_elements
        log (tab & quote & (the value of (item i of found_elements) as text) & quote)
    end repeat

    set found_elements to my getXMLElementsByName("popup", contents of xmlData)
    log ("Found " & (count of found_elements) & " <popup> nodes")       
end tell

on getXMLElementsByName(search_name, search_xml_element)

    set found to {}

    using terms from application "System Events"            
        tell search_xml_element
            set c to the count of XML elements
            repeat with i from 1 to c
                if (the name of XML element i is search_name) then
                    set found to found & {XML element i}
                end if

                if (the (count of XML elements of XML element i) > 0) then
                    set children_found to my getXMLElementsByName(search_name, XML element i)
                    if (the (count of children_found) > 0) then
                        set found to found & children_found
                    end if
                end if

            end repeat
        end tell
    end using terms from

    return found
end getXMLElementsByName
