在xml文件中使用xmlread搜索文本 [英] search a text using xmlread in xml file
问题描述
我想在xml文件中搜索文本并检查其值是否正确 使用Matlab.
I would like to search a text in xml file and check that it has the correct value using Matlab.
我尝试过:
myFolder = 'folder1';
OutputFile = fullfile(myFolder ,'info.xml');
xmlNode = xmlread(OutputFile );
我想检查"characteristic","color"选项是否存在,并且它们分别具有值:hybrid和red?
I would like to check that 'characteristic','color' options exists and that they have respectively the values : hybrid and red ?
info.xml内容--------------
info.xml content--------------
<?xml version="1.0" encoding="utf-8"?>
<Custom_project name="" val="True" name="file1" path="file:/C:/Users/Local/Temp/info.xml" version="1.0">
<verif="true" name="values" path="file:/C:/Users/Temp/folder1">
<optList name="values">
<opt name="color">red</option>
<opt name="police">calibri</option>
<opt name="font">blue</option>
</optList>
</verif>
<toto="myvalue" name="option1">
<opt name="myvalue_1">32</option>
<opt name="-total">All</option>
<opt name="characteristic">hybrid</option>
</toto>
推荐答案
如果不需要使用xmlread
,则这是一种可能的解决方案.不会检查同一XML选项的多个定义,因此任何匹配的选项名称-选项值对都算作匹配项.
If using xmlread
is not required, this is one possible solution. Multiple definitions of the same XML options are not checked, so any matching option name - option value pair is counted as a match.
%函数.
function [IsMatch] = xmlmatch(XMLdata, Variable, Value)
IsMatch = ~isempty(regexp(XMLdata, [ '.*<opt\s*name="', Variable, '">', Value, '</option>.*' ]));
return
%打开文件,获取文件ID
% open the file, get file ID
fid = fopen('info.xml');
%读取文件内容(假定为文本文件).
% read the file contents (assume text file).
XMLdata = fscanf(fid, '%s');
%检查XMLdata变量的值:
% check the XMLdata's variables' values:
IsColorRed = xmlmatch(XMLdata, 'color', 'red');
IsColorRed =
1
IsColorBlue = xmlmatch(XMLdata, 'color', 'blue');
IsColorBlue =
0
IsCharacteristicHybrid = xmlmatch(XMLdata, 'characteristic', 'hybrid');
IsCharacteristicHybrid =
1
IsCharacteristicHybr = xmlmatch(XMLdata, 'characteristic', 'hybr');
IsCharacteristicHybr =
0
%关闭文件.
fclose(fid);
