使用XSLT/Xpath打印值

我正在使用XSLT處理XML文檔，但無法使其工作。使用XSLT/Xpath打印值

這是我簡單的XSLT文檔。我使用了w3schools的模板。

<?xml version="1.0" encoding="ISO-8859-1"?> 
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 

<xsl:template match="/"> 
    <html> 
    <body> 
    <h1>VAT No.:</h1> 
    <table border="1"> 
     <tr bgcolor="#9acd32"> 
     <th>Prefix</th> 
     <th>Number</th> 
     </tr> 
     <tr> 
     <td><xsl:value-of select="/document/page/body/dd[1]/dd[1]/dd/table/cell[1]/para[1]/ln[1]/wd[3]" /></td> 
     <td><xsl:value-of select="/document/page/body/dd[1]/dd[1]/dd/table/cell[1]/para[1]/ln[1]/wd[4]" /></td> 
     </tr> 
    </table> 
    </body> 
    </html> 
</xsl:template> 

</xsl:stylesheet>

正如你所看到的，我只是試圖顯示給出的兩個單詞。我只將它留在表格格式中，以便儘可能少地從w3schools中更改原始代碼。

而不必在表中顯示的兩個詞，我得到這個：

What I get

除非有一些愚蠢的我失蹤的XPath是正確的。我甚至使用在線Xpath查看器來確認它。我嘗試過/，*和//的各種展示位置。以及編輯該行。

這是輸入XML的一部分。這是不完整的，因爲有一些敏感信息，但你可以看到佈局。

<?xml version="1.0" encoding="UTF-16"?> 
<?xml-stylesheet href="XSLT Stylesheet.XSL" type="text/xsl"?>

你能展示一個輸入XML的例子嗎？它是否使用任何名稱空間？ –

<document xmlns="http://www.scansoft.com/omnipage/xml/ssdoc-schema3.xsd"

此聲明將所有未加前綴的元素名稱在文件中變成一個命名空間，所以你需要一個前綴的XSLT分配給該名稱空間，然後在你的XPath表達式使用前綴：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
     xmlns:ss="http://www.scansoft.com/omnipage/xml/ssdoc-schema3.xsd"> 

    <!-- ... --> 
    <td><xsl:value-of select="/ss:document/ss:page/ss:body/ss:dd[1]/ss:dd[1]/ss:dd/ss:table/ss:cell[1]/ss:para[1]/ss:ln[1]/ss:wd[3]" /></td>

這是因爲在XPath 1.0表達式前綴的節點名稱始終指的是在一個命名空間是不節點。

與此無關，我會親自避免使用與XML文檔的精確佈局緊密相關的XPath表達式，而不是「第一個ln的第三個wd」 - 您可以改爲使用類似

<xsl:value-of select="//ss:wd[preceding-sibling::ss:wd[2] = 'VAT'] 
          [preceding-sibling::ss:wd[1] = 'No:']" />

專門針對一個wd其前兩個wd s爲「增值稅」和「No」，無論它發生發生。

「此聲明將文檔中所有未加前綴的元素名稱放入一個名稱空間中，因此您需要爲XSLT中的該名稱空間指定一個前綴，然後在XPath表達式中使用前綴」如何更改它以便我不需要這樣做？ – Dan

@你不能在XSLT（1.0）中，你必須編輯輸入XML文件以刪除名稱空間聲明。如果你有權訪問XSLT 2.0，那麼你可以使用'xpath-default-namespace'，但這在1.0中是不可用的（假設你使用了<？xml-stylesheet'我假設你使用瀏覽器來進行轉換，而瀏覽器只支持1.0）。 –

我確實有能力編輯輸入XML文件。這是否像在開始時添加額外的線一樣簡單？ – Dan

使用XSLT/Xpath打印值
