我正在嘗試使用xslt處理一些舊數據文件，並且它們在對象描述語言（ODL）中包含具有XML結構的大文本元素。我正在嘗試使用analyze-string將這些結構轉換爲xml。我可以匹配字符串，並採取適當的行動，但我無法弄清楚如何結構翻譯...使用xslt2將結構化文本轉換爲XML
輸入：
<?xml version="1.0" encoding="UTF-8"?>
<h4:HDF4map version="1.0.1"
xsi:schemaLocation="http://www.hdfgroup.org/HDF4/XML/schema/HDF4map/1.0.1/HDF4map.xsd"
xmlns:h4="http://www.hdfgroup.org/HDF4/XML/schema/HDF4map/1.0.1"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<h4:HDF4FileContents>
<h4:FileAttribute name="StructMetadata" origin="File Attribute: Arrays" combinesMultipleAttributes="true" id="ID_FA2">
<h4:stringValue>
GROUP=SwathStructure
GROUP=SWATH_1
SwathName="L2_Support_atmospheric&surface_product"
GROUP=Dimension
OBJECT=Dimension_1
DimensionName="GeoXTrack"
Size=30
END_OBJECT=Dimension_1
OBJECT=Dimension_2
DimensionName="GeoTrack"
Size=45
END_OBJECT=Dimension_2
END_GROUP=Dimension
GROUP=GeoField
OBJECT=GeoField_1
GeoFieldName="Latitude"
DataType=DFNT_FLOAT64
DimList=("GeoTrack","GeoXTrack")
END_OBJECT=GeoField_1
OBJECT=GeoField_2
GeoFieldName="Longitude"
DataType=DFNT_FLOAT64
DimList=("GeoTrack","GeoXTrack")
END_OBJECT=GeoField_2
OBJECT=GeoField_3
GeoFieldName="Time"
DataType=DFNT_FLOAT64
DimList=("GeoTrack","GeoXTrack")
END_OBJECT=GeoField_3
END_GROUP=GeoField
END_GROUP=SWATH_1
END_GROUP=SwathStructure
</h4:stringValue>
</h4:FileAttribute>
</h4:HDF4FileContents>
</h4:HDF4map>
我想給FileAttribute/stringValue的轉換爲：
<root xmlns:h4="http://www.hdfgroup.org/HDF4/XML/schema/HDF4map/1.0.1">
<group name="SwathStructure">
<group name="SWATH_1">
<SwathName>"L2_Support_atmospheric&surface_product"</SwathName>
<group name="Dimension">
<Dimension_1>
<DimensionName>"GeoXTrack"</DimensionName>
<Size>30</Size>
</Dimension_1>
<Dimension_2>
<DimensionName>"GeoTrack"</DimensionName>
<Size>45</Size>
</Dimension_2>
</group>
<group name="GeoField">
<GeoField_1>
<GeoFieldName>"Latitude"</GeoFieldName>
<DataType>DFNT_FLOAT64</DataType>
<DimList>("GeoTrack","GeoXTrack")</DimList>
</GeoField_1>
<GeoField_2>
<GeoFieldName>"Longitude"</GeoFieldName>
<DataType>DFNT_FLOAT64</DataType>
<DimList>("GeoTrack","GeoXTrack")</DimList>
</GeoField_2>
<GeoField_3>
<GeoFieldName>"Time"</GeoFieldName>
<DataType>DFNT_FLOAT64</DataType>
<DimList>("GeoTrack","GeoXTrack")</DimList>
</GeoField_3>
</group>
</group>
</group>
</root>
這是我到目前爲止有：
