---更新3: 我有脚本将所需数据更新到已完成的xml文件中,但下面的代码正在从写入的文件中删除。为什么是这样?我怎样才能取代它?使用python搜索并替换xml /文本文件中的多行
<?xml version="1.0" encoding="utf-8"?><?xml-stylesheet type='text/xsl' href='ANZMeta.xsl'?>
当前工作代码(上述问题除外)。

问题以下基本代码是用XML代码打交道就像
- <spdom>
<keyword thesaurus="">GDA94</keyword>
<keyword thesaurus="">GRS80</keyword>
<keyword thesaurus="">Transverse Mercator</keyword>
<keyword thesaurus="">Zone 55 (144E - 150E)</keyword>
</spdom>
由于关键字...在<spdom>
内不是唯一的,我们可以按照来自
FileDesc_obj.spatialReference.name
u'GCS_GDA_1994'

我建立了一个项目来产生我们的图书馆从空间文件的XML元数据文件。我已经创建了脚本以从文件中提取所需的空间和属性数据,并创建基于shp和文本文件的文件索引,但现在我想将此信息写入基本元数据xml文件,该文件通过将文件写入anzlic标准由普通/静态元素保存的值...
因此,例如,我想与
<northbc> GeneratedValue_[desc.extent.XMax] /<northbc>
<southbc> GeneratedValue_[desc.extent.XMax] </southbc>
问题,以取代以下XML代码
<northbc>8097970</northbc>
<southbc>8078568</southbc>
的是,明明数/值之间和将不会是相同的。
类似的xml标签,如<title>, <nondig><formname>
etc ...在后面的例子中,两个标签必须一起搜索,因为formname多次出现(不是唯一的)。
我使用Python的正则表达式手册[这里] [1],

谢谢...我不想从头开始编写一个xml文件。我只想根据来自arcpy模块的输入来替换给定属性中的文本块。 – GeorgeC 2012-01-30 03:21:37
因此,当它产生看起来像'<! - Comment - > 8097970 '的输出时,你的正则表达式会处理它吗? –
