# HTML Strip Character Filter
**HTML Strip Character Filter ** 会删除文本中**的HTML**元素,并且将**HTML**实体替换成对应的解码值(例如用**&**替换**&**)。
**案例**
|
`POST _analyze`
`{`
`"tokenizer": "keyword",`
`"char_filter": [ "html_strip" ],`
`"text": "<``p``>I'm so <``b``>happy</``b``>!</``p``>"`
`}`
|
keyword分词器只会返回一个词元(**term**)。
上面的案例将会返回如下的词元(**term**):
|
`[ \nI'm so happy!\n ]`
|
同样的案例,如果使用标准分词器(**standar tokenizer**)将会返回的词元(**term**)如下:
|
`[ I'm, so, happy ]`
|
## 配置
**HTML Strip Character Filter** 接收如下参数:
|
参数名称
|
说明
|
| --- | --- |
| `escaped_tags` | 会原始文本中保留的一系列标签 |
配置案例:
|
`PUT my_index`
`{`
`"settings": {`
`"analysis": {`
`"analyzer": {`
`"my_analyzer": {`
`"tokenizer": "keyword",`
`"char_filter": ["my_char_filter"]`
`}`
`},`
`"char_filter": {`
`"my_char_filter": {`
`"type": "html_strip",`
`"escaped_tags": ["b"]`
`}`
`}`
`}`
`}`
`}`
`POST my_index/_analyze`
`{`
`"analyzer": "my_analyzer",`
`"text": "<``p``>I'm so <``b``>happy</``b``>!</``p``>"`
`}`
|
上面案例将返回如下结果:
|
`[ \nI'm so <``b``>happy</``b``>!\n ]`
