如何解析多个特定节点的xml

本文介绍了如何解析多个特定节点的xml的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 嘿，在我的下面的代码中，它只检查1个节点是否存在该节点。同样，我想在同一个xml中检查多个特定节点的相同内容。我怎么做。 reboot.xml < rebootexclusiondata > < memid > 123 < / memid > < siteid > 123 < / siteid > < regid > 12345 < / regid > < 由创建> tanvi < / createdby > < 已更新 > null < / updatedby > < 排除 > true < / exclusion > < dcdtime > 2015-08-25 10:12:13 < / dcdtime > < updcdtime > 2015-08-25 10:12:13 < / updcdtime > < / rebootexclusiondata > xmlparse.cpp： void queryNodes（） { HRESULT hr = S_OK; IXMLDOMDocument * pXMLDom = NULL; IXMLDOMNodeList * pNodes = NULL; IXMLDOMNode * pNode = NULL; IXMLDOMNode * pNode1 = NULL; BSTR bstrQuery1 = NULL; BSTR bstrQuery2 = NULL; BSTR bstrNodeName = NULL; BSTR bstrNodeValue = NULL; VARIANT_BOOL varStatus; VARIANT varFileName; VariantInit（& varFileName）; //< siteid> 123< / siteid> CHK_HR（CreateAndInitDOM（& pXMLDom））; CHK_HR（VariantFromString（Lstocks.xml，varFileName））; CHK_HR（pXMLDom-> load（varFileName，& varStatus））; if（varStatus！= VARIANT_TRUE） { CHK_HR（ReportParseError（pXMLDom，无法从stocks.xml加载DOM。））; } //查询单个节点。 // bstrQuery1 = SysAllocString（L// rebootexclusiondata [2] / *）; bstrQuery1 = SysAllocString（L// rebootexclusiondata // exclusion //）; CHK_ALLOC（bstrQuery1）; CHK_HR（pXMLDom-> selectSingleNode（bstrQuery1，& pNode））; if（pNode） { printf（selectSingleNode的结果：\ n）; CHK_HR（pNode-> get_nodeName（& bstrNodeName））; CHK_HR（pNode-> get_xml（& bstrNodeValue））; SysFreeString（bstrNodeName）; printf（Node，<％S>：\ n，bstrNodeName）; printf（\ t％S \ n％S \ n，bstrNodeValue）; if（0 == wcscmp（bstrNodeValue，L< exclusion> true< / exclusion>）） { printf（\ n exe exit \\\ \ n ）; } 其他 { printf（\ n更进一步！让我们重启系统\ n \\ n）; } SysFreeString（bstrNodeValue）; SAFE_RELEASE（pNode）; } 现在在此代码中检查是否 < siteid> 123< / siteid> 与 < 排除 > true < / exclusion > 或不是解决方案 如果你最好阅读文档，你会发现函数IXMLDOMNode::get_nextSibling 。 就在那里。通常，接口和类提供API，其中包含所有标准任务。这是一个高品质的功能。 ; - ） hey guys in my below code it checks for only 1 node whether that node is present or not. similarly i want to check the same for multiple specific node in same xml. so how do i do it.reboot.xml<rebootexclusiondata><memid>123</memid><siteid>123</siteid><regid>12345</regid><createdby>tanvi</createdby><updatedby>null</updatedby><exclusion>true</exclusion><dcdtime>2015-08-25 10:12:13</dcdtime><updcdtime>2015-08-25 10:12:13</updcdtime></rebootexclusiondata>xmlparse.cpp:void queryNodes(){HRESULT hr = S_OK;IXMLDOMDocument *pXMLDom = NULL;IXMLDOMNodeList *pNodes = NULL;IXMLDOMNode *pNode = NULL;IXMLDOMNode *pNode1 = NULL;BSTR bstrQuery1 = NULL;BSTR bstrQuery2 = NULL;BSTR bstrNodeName = NULL;BSTR bstrNodeValue = NULL;VARIANT_BOOL varStatus;VARIANT varFileName;VariantInit(&varFileName);//<siteid>123</siteid>CHK_HR(CreateAndInitDOM(&pXMLDom));CHK_HR(VariantFromString(L"stocks.xml", varFileName));CHK_HR(pXMLDom->load(varFileName, &varStatus));if (varStatus != VARIANT_TRUE){CHK_HR(ReportParseError(pXMLDom, "Failed to load DOM from stocks.xml."));}// Query a single node.//bstrQuery1 = SysAllocString(L"//rebootexclusiondata[2]/*");bstrQuery1 = SysAllocString(L"//rebootexclusiondata//exclusion//");CHK_ALLOC(bstrQuery1);CHK_HR(pXMLDom->selectSingleNode(bstrQuery1, &pNode));if (pNode){printf("Result from selectSingleNode:\n");CHK_HR(pNode->get_nodeName(&bstrNodeName));CHK_HR(pNode->get_xml(&bstrNodeValue));SysFreeString(bstrNodeName);printf("Node, <%S>:\n", bstrNodeName);printf("\t%S\n%S\n", bstrNodeValue);if (0 == wcscmp(bstrNodeValue, L"<exclusion>true</exclusion>")){printf("\n exe exit \n\n");}else{printf("\n go further! lets reboot the system\n\n");}SysFreeString(bstrNodeValue);SAFE_RELEASE(pNode);}now in this code it checks whether<siteid>123</siteid> is present along with <exclusion>true</exclusion>or not 解决方案 If you had better read the documentation you would had found the function IXMLDOMNode::get_nextSibling.It's all there. Normally interfaces and classes provide an API in which all standard tasks are included. It is a quality feature. ;-) 这篇关于如何解析多个特定节点的xml的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
