我在使用元素树进行XML解析时遇到问题,我想解析该文件:
if(count($profiles) > 0){
return redirect()->action('NameController@name');
}else{
return view('user');
}
这是我的代码:
<?xml version="1.0" encoding="UTF-8"?>
<Metrics xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://standards.iso.org/iso-iec/19086/-2/ed-1/en">
<Metric description="CloudServiceAvailability" source="example" id="M_AVL_002" scale="RATIO">
<Parameter id="P_001" parameterStatement="2.592 x10^6" unit="second"
note="Parameter represents a 30 day billing cycle in seconds"/>
<Expression id = "E_001" expressionStatement=" 100 x (P_001- M_TQD_001)/P_001" expressionLanguage="ISO80000" unit="percentage"/>
<UnderlyingMetricRef refid="M_TQD_001"/>
</Metric>
<Metric description="TotalQualifiedDowntime" source="example" id="M_TQD_001" scale="RATIO" >
<Expression id="E_001" expressionStatement="Σ(M_QDT_001)" expressionLanguage="ISO80000" unit="second"/>
<UnderlyingMetricRef refid="M_QDT_001"/>
</Metric>
</Metrics>
问题是我的程序永远不会进入循环。我已经阅读了所有相关主题并尝试过:
for metric in root.findall('Metric'):
print("COUCOU1")
paramsTable=[]
rulesTable=[]
expressionsTable=[]
metricTable={}
metricTable['id']=metric.get('id')
metricTable['desc']=metric.get('description')
但没有任何效果,我不知道出了什么问题!
编辑:由于XML文件的结构,该问题与其他问题不同
