使用的xml文件如下
<?xml version="1.0" encoding="UTF-8"?>
<SearchConstraints>
<Begin>glucose</Begin>
<End>Ethanol</End>
<Interface>name</Interface>
<IntermediatesInclude number="0"></IntermediatesInclude>
<IntermediatesExclude> number="0"></IntermediatesExclude>
<Organisms type="all"></Organisms>
<KShort>10</KShort>
</SearchConstraints>
<StoPList>
<StoP>
<Source id="glucose"></Source>
<Target id="Ethanol"></Target>
<RouteList>
</RouteList>
</StoP>
</StoPList>問題所在：沒有加根標籤呀！ XML檔案只能有一個根標籤！
把xml改成下面這樣就ok了，也就是加上一個Document標籤，將先前的兩個根標籤SearchConstraints和StoPList都放到Document標籤的下面，從而整個XML檔案只有一個根標籤。
<?xml version="1.0" encoding="UTF-8"?>
<Document>
<SearchConstraints>
<Begin>glucose</Begin>
<End>Ethanol</End>
<Interface>name</Interface>
<IntermediatesInclude number="0"></IntermediatesInclude>
<IntermediatesExclude> number="0"></IntermediatesExclude>
<Organisms type="all"></Organisms>
<KShort>10</KShort>
</SearchConstraints>
<StoPList>
<StoP>
<Source id="glucose"></Source>
<Target id="Ethanol"></Target>
<RouteList>
</RouteList>
</StoP>
</StoPList>
</Document>以上是XML檔案要有根標籤（錯誤）的程式碼解決分享的詳細內容。更多資訊請關注PHP中文網其他相關文章！
