最近几天我一直在努力解决一个代码问题，即让 java 脚本从 SVG 中的表中显示 XML。我确实在这里问过，但没有得到答复，我明白为什么，因为它比我想象的要容易得多。

我已经解决了这个问题，但再次陷入困境，虽然我有一个状态显示了正确的详细信息，但我需要对其余状态执行此操作，我想知道是否需要为每个状态提供 XSLT，或者如果我可以在同一个 xslt 上完成这一切吗？

<script>
function loadXMLDoc(filename)
{
if (window.ActiveXObject)
  {
  xhttp = new ActiveXObject("Msxml2.XMLHTTP");
  }
else 
  {
  xhttp = new XMLHttpRequest();
  }
xhttp.open("GET", filename, false);
try {xhttp.responseType = "msxml-document"} catch(err) {} // Helping IE11
xhttp.send("");
return xhttp.responseXML;
}

function California()
{
xml = loadXMLDoc("vaults.xml");
xsl = loadXMLDoc("map.xsl");
// code for IE
if (window.ActiveXObject || xhttp.responseType == "msxml-document")
  {
  ex = xml.transformNode(xsl);
  document.getElementById("vaulttable").innerHTML = ex;
  }
// code for Chrome, Firefox, Opera, etc.
else if (document.implementation && document.implementation.createDocument)
  {
  xsltProcessor = new XSLTProcessor();
  xsltProcessor.importStylesheet(xsl);
  resultDocument = xsltProcessor.transformToFragment(xml, document);
  document.getElementById("vaulttable").appendChild(resultDocument);
  }
}

这就是主要的 html 页面，目前它有 CA 和 NV，我当前拥有的 XSLT 在下面的 XML 文件中的状态上执行了 select 的 XSL 值 

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="/">
  <html>
  <body>
  <h2>Vault found in state</h2>
  <table border="1">
    <tr bgcolor="#9acd32">
      <th style="text-align:left">vaultname</th>
    </tr>
    <xsl:for-each select="vaults/vault[state='California']">
    <tr>
      <td><xsl:value-of select="vaultname" /></td>
    </tr>
    </xsl:for-each>
  </table>
  </body>
  </html>
</xsl:template>

</xsl:stylesheet>

所以我这里的 XML 是两个州各一个保险库的精简版本，所以如果您单击加利福尼亚州，它会显示洛杉矶保险库，现在我想要它，所以我只需要单个 XSL每个州的文件。目前，如果我从 map.html 页面复制该函数并为每个状态重命名该函数并拥有单独的 XSL 文件，我就可以做到这一点，但必须有一种更简洁的方法来执行此操作

<?xml version="1.0"?>
<vaults xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="vaults.xsd">
  <vault>
    <vaultname>Los Angeles Vault </vaultname>
    <state>California</state>
    <location>Los Angeles (Cathedral)</location>
    <description>The Vault-Tec demonstration vault. It was not part of the experiment, and was the Master's vault under the Cathedral. </description>
    <fate> </fate>
    <appearance>Fallout</appearance>
  </vault>
  <vault>
    <vaultname>Vault 3</vaultname>
    <state>Nevada</state>
    <location>West of Las Vegas</location>
    <description>A control vault designed to open after 20 years, but kept closed longer due to the wishes of the vault inhabitants.</description>
    <fate> unplanned water leak forced the occupants to open in hopes of trading with the outside. Unfortunately, all of the vault's residents were massacred by a group of raiders known as the Fiends shortly after they opened the vault door.</fate>
    <appearance>Fallout New Vegas</appearance>
  </vault>
</vaults>

因此，当一个人点击 CA 时，会显示一个表格，该表格在页面底部的 div 中显示保管库名称，我希望如果他们选择 NV，它将显示 NV 的保管库

最佳答案

您可以将参数传递到 xslt-stylesheet，如下所示:

xsltProcessor.setParameter(null,"state","California");

然后在您的 XSLT 中您可以执行以下操作

<xsl:for-each select="vaults/vault[state=$state]">
