Вот HTML-код, который я пытаюсь очистить с помощью Xpath: 

<table class="ClassGrid" cellspacing="0" cellpadding="0" border="0" id="_ctl0_phMainContent_dgrdClasses" style="border-collapse:collapse;">

    <tr>
        <td class="ClassGridRow1" colspan="3">

И я пытаюсь вернуть значение ClassGridRow1 , ClassGridRow2 и ClassGridBox3 , если ClassGridRow1 содержит текстовую строку

"Адрес 123"

например. Пока что мне не повезло получить что-либо, кроме содержимого узла контекста. Кто-нибудь может помочь? Самый ценный!

Если у вас есть все функции XPath, вы можете выбрать узел <div class="ClassGridBox1"> и пометить text() с помощью регулярное выражение fn:replace: 

//tbody/tr/td/div[@class="ClassGridBox1"]/[replace(text(),'(^[a-zA-Z.-]+ [0-9]+).*','$1', 's')]

Демо

Или немного расслаблен после некоторой обработки текстового сообщения: 

//tbody/tr/td/div[@class="ClassGridBox1"]/text()
