我在编辑XML文件时遇到问题。我目前正在尝试使用Nokogiri,但我可以使用任何其他Ruby库来解决这个问题。
我正在尝试在另一个节点集中添加一个Node集。两者都有一些有趣的命名空间。这是代码。我正在尝试在第一个<p:sp>
require 'rubygems'
require 'nokogiri'
parent = <<EOF
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<p:sld xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:mv="urn:schemas-microsoft-com:mac:vml" xmlns:p="http://schemas.openxmlformats.org/presentationml/2006/main" mc:Ignorable="mv" mc:PreserveAttributes="mv:*">
<p:spTree>
<p:sp>
<p:nvSpPr>
<p:cNvPr id="1" name="Title 1"/>
</p:nvSpPr>
</p:sp>
</p:spTree>
</p:sld>
EOF
new_node = <<EOF
<p:sp>
<p:cNvPr id="2" name="Title 2"/>
<a:off x="1524000" y="4572000"/>
</p:sp>
EOF
@doc = Nokogiri::XML(parent)
@doc.xpath('.//p:sp').after(new_node)
在上面的代码运行之后,@doc看起来像下面的XML:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<p:sld xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:mv="urn:schemas-microsoft-com:mac:vml" xmlns:p="http://schemas.openxmlformats.org/presentationml/2006/main" mc:Ignorable="mv" mc:PreserveAttributes="mv:*">
<p:spTree>
<p:sp>
<p:nvSpPr>
<p:cNvPr id="1" name="Title 1"/>
</p:nvSpPr>
</p:sp>
<p:p:sp>
<p:p:cNvPr name="Title 2" id="2"/>
<p:a:off x="1524000" y="4572000"/>
</p:p:sp>
</p:spTree>
</p:sld>
注意它再次命名为p:下的所有内容。两个节点应该是<p:sp>
和<a:off>
而不是<p:p:sp>
和<p:a:off>
我可以从new_node中删除p:但是a:off仍将在p下命名为:它不可能。我知道我一定做错了。我正在寻找的最终结果是:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<p:sld xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:mv="urn:schemas-microsoft-com:mac:vml" xmlns:p="http://schemas.openxmlformats.org/presentationml/2006/main" mc:Ignorable="mv" mc:PreserveAttributes="mv:*">
<p:spTree>
<p:sp>
<p:nvSpPr>
<p:cNvPr id="1" name="Title 1"/>
</p:nvSpPr>
</p:sp>
<p:sp>
<p:cNvPr name="Title 2" id="2"/>
<a:off x="1524000" y="4572000"/>
</p:sp>
</p:spTree>
</p:sld>

看起来像Nokogiri是个问题。 Hpricot来救援! (RIP _why)
#!/usr/bin/ruby
require 'rubygems'
require 'hpricot'
parent = <<EOF
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<p:sld xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:mv="urn:schemas-microsoft-com:mac:vml" xmlns:p="http://schemas.openxmlformats.org/presentationml/2006/main" mc:Ignorable="mv" mc:PreserveAttributes="mv:*">
<p:spTree>
<p:sp>
<p:nvSpPr>
<p:cNvPr id="1" name="Title 1"/>
</p:nvSpPr>
</p:sp>
</p:spTree>
</p:sld>
EOF
new_node = <<EOF
<p:sp>
<p:cNvPr id="2" name="Title 2"/>
<a:off x="1524000" y="4572000"/>
</p:sp>
EOF
doc = Hpricot(parent)
doc.search('//p:sp').after(new_node)
输出是:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<p:sld mc:PreserveAttributes="mv:*" xmlns:p="http://schemas.openxmlformats.org/presentationml/2006/main" mc:Ignorable="mv" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" xmlns:mv="urn:schemas-microsoft-com:mac:vml" xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006">
