Question

File1.xml

   <!DOCTYPE qgis PUBLIC 'http://mrcc.com/qgis.dtd' 'SYSTEM'>
    <qgis projectname="" version="2.6.1-Brighton">
        <title></title>
         <mapcanvas>

        </mapcanvas>
      </qgis>

File2.xml

<?xml version="1.0" ?>
<legend updateDrawingOrder="true">
    <legendlayer checked="Qt::Checked" name="Grid1.shp" open="true" showFeatureCount="0">
        <filegroup hidden="false" open="true">
            <legendlayerfile isInOverview="0" layerid="Grid1_shp20150117231830763" visible="1"/>
        </filegroup>
    </legendlayer>
    <legendlayer checked="Qt::Checked" name="world_countries.shp" open="true" showFeatureCount="0">
        <filegroup hidden="false" open="true">
            <legendlayerfile isInOverview="0" layerid="world_countries_shp20150117231830790" visible="1"/>
        </filegroup>
    </legendlayer>
</legend>

我需要File1.XML到File2.XML的一部分...在脚本下面打印所需的但仅用于元素。如何将此更新保存在File2.XML中？

from xml.etree import ElementTree as et

tree1 = xml.etree.ElementTree.parse('File1.xml')
root1 = tree1.getroot()

tree2 = xml.etree.ElementTree.parse('File2.xml')
root2 = tree2.getroot()

root2.insert(0,root1)
print et.tostring(root2)

目标软件需要以下格式的标签

<!DOCTYPE qgis PUBLIC 'http://mrcc.com/qgis.dtd' 'SYSTEM'>
    <qgis projectname="" version="2.6.1-Brighton">
        <title></title>
<legend updateDrawingOrder="true">
    <legendlayer checked="Qt::Checked" name="Grid1.shp" open="true" showFeatureCount="0">
        <filegroup hidden="false" open="true">
            <legendlayerfile isInOverview="0" layerid="Grid1_shp20150117231830763" visible="1"/>
        </filegroup>
    </legendlayer>
    <legendlayer checked="Qt::Checked" name="world_countries.shp" open="true" showFeatureCount="0">
        <filegroup hidden="false" open="true">
            <legendlayerfile isInOverview="0" layerid="world_countries_shp20150117231830790" visible="1"/>
        </filegroup>
    </legendlayer>
</legend>

但是，您已经构建和/或修改了元素树，可以使用write方法将其保存到磁盘：

tree2.write('File2.xml')

ElementTree从另一个文件插入元素并保存
