下面我有一个用于跟踪库存的 Adob​​e XML swidtag 示例。我需要使用 bash 解析出相关信息并将其输出到一个新的文本文件。仅供参考，我在 Mac 上使用终端。

例如我想解析以下

swid:entitlement_required_indicator
swid:product_title
swid:product_version
swid:name
swid:numeric
swid:major
swid:minor
swid:build
swid:review

我试过使用

xmllint --xpath '//swid:product_version/swid:name/text()' nameoffile.xml

Creative Suite 5 的示例标签文件 以下示例适用于 Adob​​e Photoshop CS5，序列化为 Creative Suite 5 Master Collection (Suite)

<?xml version="1.0" encoding="utf-8"?>
<swid:software_identification_tag xsi:schemaLocation="http://standards.iso.org/iso/19770/-2/2008/schema.xsd software_identification_tag.xsd" 
     xmlns:swid="http://standards.iso.org/iso/19770/-2/2008/schema.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

也许我误解了你的问题。为什么不

grep '<swid:' inputfile | sed 's/<\/.*//'

或非常接近它的东西（例如适当的转义）工作？
