XSL含糊不清的規則混淆

Question

我收到了一個引發我的模糊規則匹配錯誤。這是錯誤：

Recoverable error 
    XTRE0540: Ambiguous rule match for 
    /dmodule/content[1]/description[1]/levelledPara[2]/levelledPara[4]/table[1] 
Matches both "table[parent::levelledPara] | table[parent::proceduralStep]" on line 3047 of 
    file:/c:/users/c79460/AppData/Local/PWC%20PDF%20Generator/test3.xsl 
and "table[not(parent::levelledPara)] | table[not(parent::proceduralStep)]" on line 2962 
    of file:/c:/users/c79460/AppData/Local/PWC%20PDF%20Generator/test3.xsl 

我沒有看到根據引用的兩個規則和它匹配的路徑可能存在任何歧義。在我看來，這個表格有一個levelledPara父級，所以爲什麼我會用not（parent :: levelledPara）的規則匹配來獲得模糊性？我敢肯定，我可能錯過了一些荒謬簡單的東西，希望一些新鮮的觀點能夠抓住它。僅僅是因爲我在使用兩個不同父級標籤（levelledPara和proceduralStep）的match語句中有「or」？

Answer 1

這是因爲levelledPara/table比賽都table[parent::levelledPara]和table[not(parent::proceduralStep)]。你大概的意思是寫：而不是

<xsl:template match="table[not(parent::levelledPara or parent::proceduralStep)]"> 

：

<xsl:template match="table[not(parent::levelledPara)] | table[not(parent::proceduralStep)]"> 

Is it simply because I have an "or" in the match statements using two different parent tags (levelledPara and proceduralStep)?

但你沒有一個or。您有union運營商。而你是工會表，而不是他們的父母。這也可以發揮作用：

<xsl:template match="table[not(parent::levelledPara | parent::proceduralStep)]">
