Question

我想搜索所有带有＆＃34; Sample＆＃34;的MarkLogic文档。作为元素＆＃34;标记名＆＃34;的值使用属性＆＃34; attr＆＃34;和价值＆＃34; attr＆＃34;使用Java API

#include <stdio.h>
#include <stdint.h>

#define nMAX 5
#define rMAX 1024




void quickSort(int arr[], int left, int right) {
    int* arr0=arr;
    int left0=left;
    int right0=right;

Answer 1

使用Java API，您可以使用containerQuery()来匹配元素＆＃34;标记名＆＃34;中包含的子结构，然后使用带有and()约束的value() tagname/@attr="attr"的{{3}}和ElementAttribute value()的另一个tagname约束，其值为＆＃34; Sample＆＃34;。

// create the client
DatabaseClient client = 
    DatabaseClientFactory.newClient(host, port, user, password, authType);
// create a manager for searching
QueryManager queryMgr = client.newQueryManager();    
// create a query builder
StructuredQueryBuilder qb = new StructuredQueryBuilder();

// build a search definition
StructuredQueryDefinition query = 
  qb.containerQuery(
    qb.element("tagname"),
    qb.and(
      qb.value(
        qb.elementAttribute(
          qb.element("tagname"),
          qb.attribute("attr")
        ),
        "attr"),
      qb.value(
        qb.element("tagname"),
        "Sample"
      )
    )
  );

// run the search
queryMgr.search(query, resultsHandle);

Answer 2

您要找的是cts:element-attribute-value-query。

您需要将其包装在cts:search中并限制它。根据您的需要，您可能需要＆＃34;和＆＃34;如果您关心元素和属性的值，则使用元素值查询。

如果您要在MarkLogic中进行大量查询，可能需要查看https://docs.marklogic.com/guide/search-dev上的搜索开发人员指南
