【问题标题】：How add attribute to Sphinx index from scheme?如何从方案中将属性添加到 Sphinx 索引？

【问题描述】：

我使用 PHP XMLWriter：

$xmlwriter->startElement('sphinx:schema');

   $xmlwriter->startElement('spinx:attribute');
     $xmlwriter->writeAttribute("name", "path");
     $xmlwriter->writeAttribute("type", "string");
   $xmlwriter->endElement(); // attr

   $xmlwriter->startElement('sphinx:field');
      $xmlwriter->writeAttribute("name", "content");
   $xmlwriter->endElement(); // field

$xmlwriter->endElement(); // schema

$xmlwriter->startElement('sphinx:document');
   $xmlwriter->writeAttribute("id", 1);
   $xmlwriter->writeAttribute("path", "TEST_ATTRIBUTE");
   $xmlwriter->startElement("content");
      $xmlwriter->text("TEST_CONTENT");
   $xmlwriter->endElement(); // field
$xmlwriter->endElement(); // doc
$xmlwriter->endElement(); // docset

所以我得到：

<?xml version="1.0" encoding="UTF-8"?>
<sphinx:docset>
  <sphinx:schema>
    <spinx:attribute name="path" type="string"/>  - why there is '/>' not '>'?
    <sphinx:field name="content"/>
  </sphinx:schema>

  <sphinx:document id="1" path="TEST_ATTRIBUTE">
    <content>TEST_CONTENT</content>
  </sphinx:document>
</sphinx:docset>

所以我尝试： indexer --rotate --all --config /etc/sphinxsearch/sphinx.conf 狮身人面像 2.2.11-id64-release (95ae9a6) 使用配置文件'sphinx.conf'... 索引索引'test1'...

警告：属性计数为 0：切换到无 docinfo

所以我没有在索引中获得属性。

【问题讨论】：

您的 XML 编写器代码是什么样的？
至少应该是->writeAttribute("type", "string");，但也要阅读php.net/manual/en/function.xmlwriter-write-attribute.php上的cmets
感谢 barryhunter！抱歉，我尝试了很多纠正我的问题

【解决方案1】：

好像打错字了……

$xmlwriter->startElement('spinx:attribute');
                      -----^

为什么有'/>'而不是'>'？

https://www.google.com/search?q=XML+closing+tags

每个打开的标签都必须关闭。 XML 对此很迂腐。然而，如果标签为空（无内容），则单个标签可以同时作为如果以 /> 而不是 > 结尾，则打开和关闭标签。 XML - Libxml2http://www.xmlsoft.org/XMLinfo.html

这是正确的代码！！！

$xmlwriter = new xmlWriter();
$xmlwriter->openMemory();
$xmlwriter->setIndent(true);
$xmlwriter->startDocument('1.0','UTF-8');
$xmlwriter->startElement('sphinx:docset');

$xmlwriter->startElement('sphinx:schema');

$xmlwriter->startElement('sphinx:field');
   $xmlwriter->writeAttribute("name", "content");
$xmlwriter->endElement(); // field

$xmlwriter->startElement('sphinx:attr');
  $xmlwriter->writeAttribute("name", "path");
  $xmlwriter->writeAttribute("type", "string");
$xmlwriter->endElement(); // attr

$xmlwriter->endElement(); // schema

$xmlwriter->startElement('sphinx:document');
    $xmlwriter->writeAttribute("id", 1);

  $xmlwriter->startElement("content");
    $xmlwriter->text("TEST_CONTENT2");
  $xmlwriter->endElement(); // field

  $xmlwriter->startElement("path");
    $xmlwriter->text("TEST_ATTRIBUTE2");
 $xmlwriter->endElement(); // field

$xmlwriter->endElement(); // doc

$xmlwriter->endElement(); // docset
print $xmlwriter->outputMemory(true);
